Compile your application in VB.NET. Use Visual Studio 6 IDE to debug the dll source code, using the compiled NET exe as the calling application.

We have one VB.net windows based application.It's installed on about 10 client machines.
Every time when we make any changes then we have to reinstall the application on each machine.
Can we add functionality in our application that if there is any modifcation in application then apllication installed on client machine check for update/changes and download the copy from server and installed it automatically.
I have seen this feature in most of the windows prodct but don't know how to add it.

I need to capture all the content of a non visible or partially visible window.
BitBlt works fine on the visible part of the window. Does anyone know how to capture the full content of the window when it is not visible and to display it at a smaller size on a new window.
Image capture is the fundamental problem. Thanks for your help.

Since the non-visible part of the form is never drawn, there's nothing to capture. In other words, you cannot capture what you cannot see. This will change in "Avalon", which is the new graphics package coming in Windows "Longhorn".

OK, i have written an App using SQL Server and Crystal Reports. I attempted a deployment on the program but it wasnt pretty. The crystal report does not load. Even bigger, there is no SQL connection between my program and another computer because i wrote my program to connect to My SQL on my machine. Where do i start? How do i configure my App so it attaches the database and connects automatically to client SQL? Any information at all will be helpful and appreiciated.

hello
I'm new to VB.Net and even to VB..
I'm building a multiform application which contains two forms - the main form (form1) and a sub form that can be called by pressing a button at form1.
my problem is that I have a textbox in form2 where the user is supposed to enter text. in addition to a button that I added to submit the text added by the user I want to enable the enter key to do the same submit action like the button submit.
the problem is: the KeyPress() event works only at form1 but not at form2 (again- called by pressing a button at form1)
help... please...

Instead of using KeyPressed, try your code in the KeyDown event.

hello Dave
thanks for the quick reply but I already tried all the related events including the KeyDown event.
that's why I believe there is something needed to be done like setting focus or caption or something like that because all these events work fine when I use it with the main form (form1)

I am not sure I understand your problem well enough, but maybe the following will help.
All forms have the properties "AcceptButton" and "CancelButton". Set these properties to each corresponding button on your form.

Rudy is correct. You can use the AcceptButton property to get ENTER to click the submit button. But it too won't work if the form doesn't have the focus.

hello Dave and Hello Rudy
It really didn't work.. as I said it works only when I use it with form1 but not when I use it with form2 (which appears as I press a button in form1)
maybe it would help you if add that while form2 is active on the top level form1 still also active but at the background

From your descriptions, what you're saying isn't possible. There's something in your code and how your code is written that doesn't match your description of the problem. Without seeing your code for BOTH forms, we really can't tell you what's going on.
Only one form/control can have the focus at any one time. So when you say that both forms are "active", we don't know what you talking about.

You should be able to create an event or use a delegate.
For example, if Form1 creates Form2 then add an event in Form2 and subscribe Form1 to that event.
Ex:
in Form2:
Event Form2Event(text as string)
when enter key pressed in Form2 :
RaiseEvent Form2Event(text)
in Form1:
AddHandler myForm2.Form2Event, Addressof SubmitPressed(text)

Why are you telling me this? Tell the OP! That way, he get's a message that says someone replied to one of his posts.
Besides, what he's describing shouldn't be happening. There's something else he's not telling us...

I am populating a datagrid using threads.
Sometimes, the datagrid display gets distorted with double scrollbars appearing. and if click on the grid esp. the scrollbars, you get anyone of following 2 exceptions.
Try Catch blocks exist everywhere but the exception cant be trapped.
On clicking on Break(on the exception msgbox), the location of exception occurence is the begininng of the form class.
Two exceptions:
1. System.Runtime.InteropServices.SEHException' occurred in
system.windows.forms.dll
Additional information: External component has thrown an exception.
2.An unhandled exception of type 'System.NullReferenceException' occurred in
Unknown Module.
Additional information: Object reference not set to an instance of an object.
Need help urgently.

You can only manipulate controls from the primary thread. The .NET framework provides the Control.Invoke method to ease this. Check this MSDN article[^] to further details.

Dear guys
i have one problem in .net frame work designing
i have designed the winform in one mechine,and i implemented in another mechine ,but when i will
get the same design in another mechine the design will be changed like it gets big fonts and unsize to screen.how can i keep the designing settings in all mechines same and how can i write and get the registry for app settings

It sounds like you have a screen resolution problem or in the advanced settings of the screen properties the font is set larger. Its not your program its WINDOWS.

2. From discord, find harmony.

I have checked with resolution ,but thats not a problem,if resolution problem only the font is get bigger or smaller but my case the total control gets bigger or smaller in forms,in design time i have designed control is very compact in form but in another mechine it will not convenient fit
