  • How do to "BOLD" in the first line of text on a number of sections of text at a time

    CS5 using (but we have CS5

    .5 available) we will create a business directory. Each page has columns of type

    business listings with the company name on top, under this address under this phone, etc.  Each ad is separated

    by a single line. There are thousands of ads, and we need to "BOLD" in the top line of each. How can do us

    without making them individually?

    Each line a paragraph, or each list a paragraph with soft returns (forced line breaks)?

    It's very simple and basic in both cases an operation. It is especially easy if each ad has the same number of lines, so we will focus first with this case.

    Each line should be a separate paragraph. If you have 4 lines, as your example, you might want to mention their name, street, city, and phone. You can and should, all the styles that will be similar in appearance on the same basic model and change only the atrributes that are different, so, for example, if all lines use the same font, many use the same size and weight and only the top line is different and only by being "BOLD" and or larger size start by defining the street, then city and phone based Street and you don't need to define something more than the next Style, I'll get to in a second.

    For topics, set name based as well on the street, but change the font characters. Now all the features of the basic fonts can be changed in one place, the definition of the style Stree.

    Since you have the same number of lines in each list, you can set up a loop "next style". For name, style next street is, the street is the city, for the city it is the phone and is name for the phone. You will also need to toe after the add space in the name, or space on the phone to book spaces registration and you probably also consider to assign everything except phone keep with the next line to prevent a list from breaking across a page or column break. If currently you have blank lines as separators (empty paragraphs), get rid of them. There are change queries find already registered in ID that will do that.

    Once the text is in place and the styles are defined, you can select all, then right click on the style name in the paragraph Styles Panel and choose apply following Style and name. Reformatted your entire list. IT IS CRITICAL in this method that the structure of each list is identical, and if there are no empty lines between the lists.

    If each line is a paragraph, but there is line different counts, you will probably reach with just two styles, one for the headings oand one for everything else, but the beat of following style will not work. If there is something unique that appears in all the headings you can use find/replace to make search and reformat in shape, but I suspect that this will not be the case on in the real world, there will be a manual work involved.

    Where a lisitn is a single paragraph, line break forced (which is better suited to the case of an uneven lines by registration number) you can define a character style nested to be applied by means of a line break forced to make the first line "BOLD", red or any other thing you want.

    At this point, you are probbly, noting that a bit before planningn is a good idea when you do a directory so that your ads have some sort of coherent structure that allows for automation. I have no idea whre that your text is coming from or how it is done in the code. If it can be established as a .csv or a tab-delimited text file, you can use data merge to fill a file based on a model of merge (i.e., how to build directories for my clients who need). You can set styles in the model to each field or paragraph that contains several fields, and merge data will remove empty lines if all row fields are null and there is no punctuation or whitespace on the line.

    A multiple records per page fusion will give you individual blocks of text for each record, and you can, if you wish, thread them using the script text point of Rorohiko.com.

  • Extract the first line containing "critical" or "E-Stop" of the last avalanche of line

    Hi all

    I'm watching some test systems by analyzing their audit files.

    In this case, the platform generates several line 100 files in a specific folder. The code below is to find the last file and extract the contents of the last line of the last file.

    Unfortunately, when an error occurs, the main software generates not only one entry, but an avalanche of lines [not a specific quantity of them, depending on how much the alarms are resolved] and I'm now ideas of how I could identify and the contents of the first line containing "Criticism" or "E-Stop" to exit from this avalanche [line avalanche started 22.27].

    As an example, the above program is extract the yellow line, while I need information from the blue line.

    Any idea on how I can do this?

    See you soon,.

    You can add this snippet to the top of your existing code.  I changed the indicator table to a table so I could highlight the line.

  • First character left in file by reading the first line in text file

    When you use the function of reading text from a file file, I noticed that the 1st character is left in the file. I read the line correctly.

    When adding a 2nd line this character is in the file.

    Part vi code is attached.

    Any ideas?

    Thank you.

    Elik

    Can you attach a file of real data and tell us what you mean by "first character". The number of characters per line do you have?

    Can you tell us what you see in the modified file and what you expect to see.

    Everything seems good.

    1. Read you the first line and so the file pointer is just after the first line
    2. You set the size of the file at the end (seems unnecessary, because it does nothing). The file pointer is always right after the first line.
    3. You write the first line you read concatenated with a second line. It will be written on the current file pointer, i.e. after the existing line
    4. The first line is in the file twice, as planned.

    Setting the file size to the 'end' on an existing file does not have something useful. If you want to set the position of the file instead?

    Try to set the file position from and new data will be written at the beginning of the file.

  • Scan of a file only works on the first line

    Hello

    I'm new to Labview (see 8.6) and I'm running on this problem.

    I use the Scan of a file to get a certain amount of information for the installation of test.txt.  The data of the file looks like this:

    AAA 1

    BBB 2

    REC 3

    I noticed that the Scan of the file works for only the first line.  Trying to get data that are not in the first line results in an error 85.

    Any ideas? Thank you

    It's all in what the scan of the file reads, and what is the next cgaracter in the file.

    Your first analysis of the file reads up to but NOT including the first newline in the file.

    The second read readings where the first reading was arrested and is expected to see 'B' as the next character, but sees the new line instead, and if the analysis fails. You must specify second reading formatted to await the return line.

    You can do this by making the FIRST character of the format string space, that will tell it to expect a number any of charaters 'white space '.

    Yo can indeed put a space at the beginning of the format string in your first analysis of the file and it will match with zero white space characters before you see the AAA. By doing this he also tolerate to see the spaces and tabs before your AAA or BBB identifiers.

  • HP all-in-one C310 printer prints the first line of text from the top of the page

    My printer worked fine for 2 years, then suddenly this week... the first printing line is missing! The first line of any text is printed only on the top of the book and at the bottom of the sheet, there is a gap between the last line of the text and the bottom of the paper. I.e. the printed text is not aligned to the Center vertically on the paper. I tried to shift from the printer and also restart the PC, but is always the same. She's also from any source print - Word or IE for example. I checked all the options of the printer and the settings of applications - everything seems OK and everything said A4 paper for example. What could be the cause of this please? I'm in Windows 8.

    No problem.  I'm happy to try to help.  I sent the steps to your Forums box.  Follow carefully and let me know how it goes.

    Good luck!

  • Mr President, how can I enter two rows at the same time with different default values that only the first line to use see?

    Mr President.

    My worm jdev is 12.2.1

    How to enter two rows at the same time with different default values that only the first line to use see?

    Suppose I have a table with four fields as below

    "DEBIT" VARCHAR2(7) , 
      "DRNAME" VARCHAR2(50),
      "CREDIT" VARCHAR2(7) , 
      "CRNAME" VARCHAR2(50),
    

    Now I want that when I click on a button (create an insert) to create the first line with the default values below

    firstrow.png

    So if I click on the button and then validate the second row with different values is also inserted on commit.

    The value of the second row are like the picture below

    tworows.png

    But the second row should be invisible. It could be achieved by adding vc in the vo.

    The difficult part in my question is therefore, to add the second row with the new default values.

    Because I already added default values in the first row.

    Now how to add second time default values.

  • How to get the cursor to the first line after the addition of 3 rows in the OPS. Help, please.

    Hi Experts,

    I have a requirement to get the cursor should point to the first line instead of pointing to the third row. To the help of code below, my cursor points to the third row. Please put some light on it to reach the requirement

    XXCLKTestVOImpl vo = getXXCLKTestVO1();

    for (int i = 0; i < 3; i ++) {}

    Line = vo.createRow ();

    vo.insertRow (row);

    row.setNewRowState (Row.STATUS_INITIALIZED);

    }

    Thank you

    Gurnur Singh

    Problem is solved. Since then, I've been on 12.2.4 Ebs version and was auto insert false setting in AddtablerowBean. To reach the requirement, you will need to refer to the same number of lines to add the addtablerowbean property that you use in loop for. here I use 3 looping so you must use the number 3 lines to add the addtablerowbean property to get there. So whenever you add three rows then cursor in the first row of three lines you will add. Thank you all.

    Thank you

  • How to select and default hightlight the first line in a programmatic Table(ADF Table created based on a SortableModel) ADF.

    Hi all


    We use JDeveloper Studio Edition Version 12.1.3.0.0 and deployed on GlassFish Server Open Source Edition 3.1.2.2 (build 5) and connect to the SQLServer database.


    We created a table ADF programming related to a SortableModel created programmatically to a bean.


    We need to select and highlight the first row in the table just after making it to retrieve data based on the first line.


    We tried the based on the following thread: How to call the bean support just after JSFF / page fragment loads? and a few other posts online, but it does not work very well.


    W has created a hidden text in the bottom of the JSF model as follows:


    < af:table varStatus = "rowStat" Summary = "table" value = "#{pageFlowScope.crudBean.dynamicTable.collectionModel} '"

    Rows = "#{pageFlowScope.crudBean.dynamicTable.collectionModel.RowCount} '"

    contentDelivery = 'immediate' var = 'row' rendered = 'true '.

    Binding = "#{backingBeanScope.crudBackingBean.tasksTable} '"

    selectionListener = "#{backingBeanScope.crudBackingBean.customListener} '"

    "rowSelection ="single"id ="t1"partialTriggers =": pt_gr2 "columnStretching =" column: clmn0 ">

    < af:forEach items = "#{pageFlowScope.crudBean.dynamicTable.columnNames}" var = 'name' varStatus 'vs' = > "

    < af:column sortable = "true" sortProperty rowHeader = "#{name}" = "no style" headerText = "#{pageFlowScope.crudBean.dynamicTable.columnLabel [name]}" "

    inlineStyle = "width: 100px;"  ID = "clmn$ {vs.index}" >

    < af:activeOutputText value = "#{row [name]}" id = "aot1" / >

    < / af:column >

    < / af:forEach >

    < / af:table >

    ....


    < af:outputText id = "hiddenOutputTextId" visible = "false" value = "#{backingBeanScope.crudBackingBean.afterPageLoad} '"

    Binding="#{backingBeanScope.crudBackingBean.hiddenOutputText}"/ >

    And we have added the code to the bean to support below:

    public String getAfterPageLoad() {}

    If (!.) {AdfFacesContext.getCurrentInstance () .isPostback ()}

    selectFirstRowInTasksTable();

    }

    Return afterPageLoad;

    }

    public void selectFirstRowInTasksTable() {}

    try {}

    RKS RowKeySet = new RowKeySetImpl();

    RowKeySet rksEmpty = new RowKeySetImpl();

    Model CollectionModel = tasksTable.getValue ((CollectionModel));

    ROWCOUNT int = model.getRowCount ();

    If (rowcount > 0) {}

    model.setRowIndex (0);

    Key of the object = model.getRowKey ();

    RKS. Add (Key);

    tasksTable.setSelectedRowKeys (rks);

    SelectionEvent selectEvent =

    new SelectionEvent (tasksTable.getSelectedRowKeys (), rks, tasksTable);

    selectEvent.queue ();

    customListener (selectEvent); / / to retrieve data

    AdfFacesContext.getCurrentInstance () .addPartialTarget (tasksTable);

    }

    } catch (Exception e) {}

    }

    }

    I think that () selectEvent.queue; should work even without calling the customerListener, but it is not working in all cases.

    What is the problem in my code?



    Have you tried to bind property of 'selectedRowKeys' to selection configuration / bean there?

    Something like:

    public RowKeySet getSelectedRKS() {
        if (rks == null) {
            // make first record as selected
            // create RowKeySet and assign it to rks variable(where rks is variable defined in bean with some scope higher than request scope)
        }
        return rks;
    }

  • First line indent except the first line of a paragraph

    Hello

    I would create a paragraph style with a first line indent, with the exception of the first line, which I have no dash.

    Attached an example of how I want it to look.

    Best regards

    Vincent

    You need a second style to the first paragraph. Based on the other model and the withdrawal of first line value of 0.

  • Delete in af:table always remove the first line when using ExecuteWithParams

    Hello world

    I got a page with master form and af:table two details related to the master. When I'm trying to remove a line in an af:table of detail, it always removes the first line, any line, I selected before. The table has a single = rowSelection and the line is properly visually selected. I remove the line using a "delete hyperlink" on each line, but I first have to select the line. Delete called a bond (or a method at the bean by removing the current line of the iterator, I tried both, none of them work)

    Links page has an ExecuteWithParams defining the correct ID to edit on the master of iterator and an InvokeExecuteWithParams the renderModel value. If I put the refresh condition zero and I hard-code an ID in the binding variable in the model, I am able to delete the selected line.

    In addition, I don't know if this information is useful, but if I set the iterator to PPR ChangeEventPolicy, when I select a line, there always select the first line.

    Any ideas what I could do wrong? Is this a bug?

    I use JDev 11.1.1.7

    Thank you

    Guillaume

    You can try creating a method in ApplicationModule for filter master records instead of executeWithParams?

  • Discover with function as datasource returns only the first line.

    Hello

    I created the following function to get the status of all the rules for the instances of SQL Server.

    The data type of the function output has been configured as 'List of SQLInstanceRuleStatuss', where SQLInstanceRuleStatuss is the custom type, I created in the same module.

    When I tested the function, it returns all instances of SQL Server with two other columns.

    But when I try to create a view with the Rows property that is configured to use the feature, it returns only the first line:

    sqlRules = new ArrayList();

    queryStatement = server. QueryService.createStatement ("(DBSS_Instance)");

    queryResult = server. QueryService.executeStatement (queryStatement);

    for (it in queryResult.topologyObjects)

    {

    sqlRule is functionHelper.createDataObject ("westjet_mark_dev:SQLInstanceRuleStatus", "none", "test");.

    sqlRule.instance = it;

    sqlRule.ruleName = 'test rule name';

    sqlRule.status = false;

    sqlRules.add (sqlRule);

    }

    Return sqlRules;

    Did I miss something?

    Thank you

    Mark

    Mark,

    I think I forgot something

    sqlRule=functionHelper.createDataObject("westjet_mark_dev:SQLInstanceRuleStatus","none","test");

    you create the test id

    change your line of

    sqlRule=functionHelper.createDataObject("westjet_mark_dev:SQLInstanceRuleStatus","none",null);

    This should allow the creation of a single object in your loop for
