Hello,

I have a intranet web page and a windows form application also.
I need to change a text box value on the windows form application, by getting a value from web page, and with a button on the page. How Can I do this? I need your help as soon as possible..
Thank you very much in advance

For Example;

Web Page = 12345 (written on a column) -> send to form (with pressıng a button)
Windows Form = 12345 -> Textbox value (first it's empty then we fill this via getting value from web page)
===============================

I decide to do web page (server side) writes the value to a somewhere inthe registry and client app should read from there.
I did this with the following script but it doesnt work when I deploy the code to the server.
Can you help me I need to finish it today:(

<script language="javascript" type="text/javascript">
function ReadRegistry() {
var WshShell;
var Key;
try {
WshShell = new ActiveXObject("WScript.Shell");
WshShell.RegWrite("HKEY_CURRENT_USER\\Software\\Clients\\id", 12345);
Key = WshShell.RegRead("HKEY_CURRENT_USER\\Software\\Clients\\id");
alert(Key);
} catch (e) {
Key = '';
}
}
ReadRegistry();
</script>
====================================

I think that the name of the Question should be changed.

4 solutions

Solution 1

Your best bet would be to use an intermediary file, like a text or xml file. When the user enters something in the textbox in the web page and clicks the button, the web page can update the text file. The winforms application can have a timer which periodically checks the text file to see if it has been updated, and if so, it can update it's own controls.

Hope this helps

timer isn't a good practice..you use FileWatcher.. as the file get modified... you read the file

Solution 2

That seems good idea, but I want to do it in real time, some people told me that,
findwindow(), childwindow() and setwindowtext() function I need to do this.
But I could not manage to figure that out. Maybe what they told is better way to solve.
Thanks

I think also that this is the way to do it correctly, you can even grab components (textField) inside your target window and set its text value, just look at windows API which make you able to handle graphic components (Windows).

Hi ,

I think also that this is the way to do it correctly, you can even grab components (textField) inside your target window and set its text value, just look at windows API which make you able to handle graphic components (Windows).

this example would help you to begin :

Retrieving Conversations from MSN Messenger[^]

look at msdn to see how to use this function and which DLL you should load :

EnumChildWindow msdn ref[^]

Here is an article about how to invoke dll functions on C# :
Calling API functions using C#[^]

changing registry key :

Read, write and delete from registry with C#[^]

best regards.

This is c++, I do understand nothing from this language actually.
Do you have any other example. I did many search, but I didnt find any.

Thanks a lot again

You will use the same windows native functions (API), but you will call them from a c# program. I've updated my answer according to your need, look if it is more helpfull for you.

Hello agaian elgaabeb,

Thank you very much for your help, but it comes to me so confusing and I talked to my manager and he accepted to using client's registry key to change value.

How can I create and write to client's registry key?

Thanks.
