• How to detect if the page is a reload or not?

  I have a form in the cfm page if the user submits the form, I don't want to go to another page. I want to reload the page and I'll capture all values and send the data in this way. However, I need to hide the form once the user submits the form. So, how I detect if the page is a reload (after is submitted) or it's the first time it is been charged?

  You can manage only two ways.  One, add a hidden field to the form that passes a value, then check if the value exists in the URL/FORM variables (if it exists, the page is reloaded by sending the form - if it does exist, it's the first load of the page).

  Perhaps a better approach would be to manage the form via an AJAX request is sent, and then hide the form if the AJAX request is successful.  This all is possible using JavaScript.  The advantage is that the user leaves the page never actually or it recharges.

• How to install the Com port in Windows 7

  I would like to use the COM port in the Toshiba laptop, but I can't find it in the Device Manager. It is important to communicate with another device via a serial port.

  Given that the PC operating system is windows 7, I have not dealt with the problem.

  Where can I get the files to install COM port?

  Or is there any facility for her?

  If someone knows solutions to the problem, let me know.

  If there is no COM port or other device showing in Device Manager you will need to activate the serial port/COM in the BIOS of the laptop, assuming that the laptop has a COM port.

• How to change the IRQ and address of some of the COM ports

  Original title: jcertain

  No, I loaded 7 a window in one of our systems.  I want to change the IRQ and address some of the COM ports and were not too.  In the pasted, you can enter the Device Manager and click on the device, then go to the "resources" tab.  There, you can find a box that allows users to disable "USE AUTOMATIC ADJUSTMENT", which would allow you to change the IRQ and address.  But for some reason any box is not highlighted so you can not.

• change the com port assigned to the fax and scan

  I used fax and scanning for once.  I had to move my external modem to a different port.

  I don't know how to change the windows fax and scan com port manually.

  the wizard does NOT start, I guess because the fax is installed and worked until I had to change the number of COM port...  I need to change the number of pot with hundreds of research, it seems that no one knows how to change manually the Compote in windows fax and scan, unless they use the wizard.

  my assistant does not start. I guess I'm 'old school' I don't need an Assistant, I need to manually change the fax uses com port.

  :-), it's frustrating because help said only: click "fax" in the lower left corner, and they all assume the installation wizard starts and everything will be fine. :-(

  the wizard does not start. :-(

  I am desperate to get my fax work and need to know how to set the correct port number in a system that is installed and running, such as the wizard never starts.

  for anyone who goes out at the end of questions and ideas, I have a fax application stand alone who is working with the new port setting. It's just not a good app for my needs

  Please?

  Thank you

  Post proposed by the moderator of the appropriate forum category

  Hi John,.

  You can follow the steps below to change the COM port for a modem:

  1. search the Device Manager.

  2 look for the Modem device, right-click on it, and then click Properties.

  • If the change settings button is present, you must click on it to make changes to the appliance. If the user account control dialog box appears, confirm that the displayed action corresponds to what you want, and then click continue.
  • If the change settings button is not present, the modem does not support the ability to change the modem settings. Refer to the documentation provided by the vendor of your modem.

  3. on the Advanced tab, click Advanced port settings.

  • If this option is not displayed, the modem does not support the ability to change the assigned COM port. Refer to the documentation provided by the vendor of your modem.

  If the same persists, we suggest that you post your query in Microsoft TechNet so that their support team will provide you in-depth assistance.

  Kind regards.

• break in series on the com port does not work

  Hello everyone:

  I have the following problem:

  I am writing a command via the ' 'entry visa' vi on my pc com port. in some cases the com port do not return anything. This means that my "visa read" vi would timeout. the problem is that, later, I need to send more orders but must break the line in order to be able to do. I inserted the "breach of visa" vi but didn't have the reaction I was expecting. the line does not break. I tried to increase the duration of the break, but that does not work either.

  Any ideas?

  By using LabVIEW 2013

  A break will not break the connection, it will just a 1 to the Tx line for a period longer than 11 baud (?) or specified length.

  A hardware check that the breakdown is send: connect a scope or a DMM TX and GND, a 500ms break must be clearly visible even on a "slow" DMM (k resistance 10 and two LED antiparrallel or RS232 minitester practice would do the same job )

• Get the error message about the COM port at startup

  Original title: COM port occupied at startup

  We get busy COM port when the system has been started and given are incoming on port.

  The COM port is connected to a PLC which retransmit if he didn't get a response.

  In this case our application cannot connect to the port.

  Is it possible that we can avoid this or is there a way to release a COM port?
