I had that problem myself and I'm not sure what best to do. Maybe there is a trick we both don't know.
If you don't have a user control, but a control derived from Panel, you can drop controls onto it at design time and they will be added. Also I think if you have a Panel on your user control, you can drop controls onto the Panel. So maybe you can just fill your user control with a Panel and go from there.

Hello everyone,
I'm currently involved in developping a WinForm application. I use VB.NET as a language and use the 2.0 .NET framework
One of my forms only contains a WebBrowser component. That form is launched by another form which passes him an URL for the WebBrowser to naviguate towards.
The webpage aimed by the URL has an applet (or so I think it is) allowing to see a digitalised document (such as a hand written letter or a printed form).
When the form is closed, the exectution of the instruction line :
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
...
MyBase.Dispose(disposing)
...
End Sub
lasts for several minutes. Within that period of time, the entire software is frozen and will only be available to the user when the instruction is passed.
I asked to my peers how to hanlde that behavior and they adviced me to come up with a solution based on asynchronous execution (I am no expert in that domain of IT programming).
So my question is: assuming that it is the correct way, which part of my code am I supposed to wrap with a thread ? Is it the form containing the WebBrowser with the heavy finalysing ? Or maybe just the finalisation itself (I must say that I already tried that and it changed nothing)
Thanks in advance for you help and accept my apologizes for my writting but english isn't my native language.

Hi,
I was wondering if its possible to make a File Dialog (Open/Save as) become the child window of a parent form and be fully "contained and bounded" in it. I can`t find any straight-forward way to do this, like Controls.Add or anything since they inherit from Component class.
I also tried calling the Win32 SetParent function but it has no effect.
Any suggestions please ?
Thanks in advance.

hi
yes is possible but: are you expert in API calls, i. e. WndProc, Farprocs, Hookprocs, HookFunctions ans so on. if not, is better you call the standard file dialog in the .net framework.
regards

Hi Joe,
Yes i`m familiar with Win32 API .Can u tell me how using HookProcs and WndProcs will help ?
|
|
|
|
|
hooks are not easy to use. look in the msdn help, set the filter to platform SDK an search for OPENFILENAME.
good luck

//Mixer mix = new Mixer(MixerType.Recording);
mix.Recording.Lines.GetMixerFirstLineByComponentType(MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Mute = true;
}
else
{
if (mix.Recording.Lines.GetMixerFirstLineByComponentType(MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Mute)
{
mix.Recording.Lines.GetMixerFirstLineByComponentType(MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Mute = false;

Hello all,
Is there a progress bar for .NET that has an unsigned 64-bit maximum value? The number of items I'm processing can easily exceed 32-bits, but the Windows Forms progress bar only accepts a standard int.
Thanks,
Dybs
|
|
|
|
|
Why don't you set the maximum to 100 and set the integer percentage value when it has changed? Setting the value a billion times will slow down your application anyway, and users won't see a difference.
|
|
|
|
|
Good point. We had created a form that has a progress window and a display of the number of items being processed, and we had just been using the ProgressBar.Maximum property for that value. But yes, your suggestion would be a better design choice.
Thanks,
Dybs

Does anyone know a good way to make a control draw and work outside the bounds of a form in vb.net? I am trying to make a control that works like a combobox in that it drops down, but I need the part that drops down to be a datagridview. If the datagridview dropdown is taller than the form has room for, I need it to go past the edge of the form, just like a combobox dropdown.
|
|
|
|
|
You can put the datagridview to a separate form without borders and position the form under the "combobox". When form looses focus, you close the form so the "combo" closes.
Hope this helps,
Mika

Thats the only thing I could think to do as well. It seems there has got to be a different, cleaner way to do it, because combobox/menu dropdowns can do it. I guess for all I know thats how combobox and menu dropdowns work too.
Anyway, this is probably what I'll end up doing. Thank you for your help.
|
|
|
|
|
You're welcome.
It's not neccessarily a bad way at all. I don't know today's implementation for example in Vista which is based on WPF but if I remember correctly, originally in Windows combobox was constructed using:
- textbox (editable or noneditable)
- button on the right side of the text box
- listbox placed in a separate window

Hi All,
I have done a windows application which is running very fine. and I made a windows service which is also running fine.
Now my windows service is on system A.
Now my windows application is on system B.
From system A through windows service I have to invoke the windows application on system B which the form consisoting in it.
Right Now Iam able to invoke the process(windows application)which is on system B from windows service which is on on system A.
But the form/pop-up is not opening in system B. but Iam able to see the windows app process in Task manager of system B.
Now how to show form/pop-up of winodws app in system B where it is invoked by system A.
Thanks
Kinldy help me...

You can't do this. Starting an interactive process remotely is not allowed by Security, and for VERY good reasons.

It's amazing how some people just don't think of the security ramifications when asking these kind of questions.

Dave comment is important, but you may want to play with the interact with Desktop option of your service.
-- modified
- not sure if it will work in a remote scenario, but it is worth trying it out.
|
|
|
|
|
It still won't launch an app on a remote machine so the user can see it.
|
|
|
|
|
i just dont know yet how you did it.but in case you were running/invoking the windows application from onStart()method of the windows service,use the MMConsole,navigate to services,look for the name of your windows service->properties,logon tab,check the checkbox--allow service to interact with Desktop.ope it works
was wondering if you culd help with your code for this application(both winform and winservice)

hrmm, this is a little open-ended. What type of animation are you referring to? Does the animation relate to events in the application? Need more info to advise.
