I have been trying to start multiple instances of iexplore and other
apps then get the handle so i can reposition it and other actions.
It works great in Windows 7 using myProcess.Id to find the process and retrieve the MainWindowHandle. It also works in Windows 8.1 if there is
only 1 instance of the application running.
The Problem: When i get more than one instance of the app open in W8.1 I can not find the handle. I can get the process id but can't get the handle even by looping through all processes and looking for the handle.
Help

Can you post a SMALL examle that reproduces this problem?

string ProcToStart = "iexplore";
int saveProcId;
Process myProcess = new Process();
myProcess.StartInfo.FileName = TargetFile;
myProcess.StartInfo.Arguments = TargetArguments;
myProcess.StartInfo.UseShellExecute = true;
myProcess.Start();
saveProcId = myProcess.Id;
1-the simple approach, just trying to access myProcess.MainWindowHandle gets 0 even after a 10 min sleep
2--here is one method looping through all processes
I also tried this wraped in: while (proc.MainWindowHandle == IntPtr.Zero) (ran forever & didnt find a hit)....
foreach (Process proc in Process.GetProcesses())
{
if (proc.Id == saveProcId)
{
Console.WriteLine(" PID: " + proc.Id + " Handle: " + proc.MainWindowHandle);
}
}
3--Here is another attempt using ....GetProcessById
try
{
ChosenProc = Process.GetProcessById(ProcId);
Console.WriteLine("Your Process Info: " );
Console.WriteLine(" Id: " + ChosenProc.Id
+ " Handle: " + ChosenProc.Handle
+ " MainWinHndl: " + ChosenProc.MainWindowHandle
+ " Name: " + ChosenProc.ProcessName);
return true;
}
catch
{
ChosenProc = null;
Console.WriteLine("Incorrect entry.");
return false;
}

InvalidOperationException? Try using the full path to the application;
Process myProcess = new Process();
myProcess.StartInfo.FileName = @"C:\Program Files\Internet Explorer\iexplore.exe";
myProcess.StartInfo.Arguments = @"http://www.codeproject.com";
myProcess.Start();
Console.WriteLine(myProcess.Id);
Console.ReadLine();

Thanks...
I just tried it both ways (fully qualified and just the iexplore) followed by:
Console.WriteLine("IE Instance started... PID= " + myProc.Id + myProc.MainWindowHandle);
I get an unhandled exception on the myProcess.MainWindowHandle no matter how much of a sleep or if i loop looking for the process id. Again, it works find if there is only 1 instance of the target app (iexplor in this case) open.

I run an indoor sports facility.
Our receptionist uses some media player for background music in our foyer.
What I need is a way to mute that media player, to play my own .wav file to remind players to be ready 10 minutes before events start, (triggered by system time) then resume the background media player.
If that makes sense?
My application is in C# and uses AXVLC.
Im also considering making it a Service instead, so the receptionist doesnt close it.

Uhm what is your question, does it make sense, yes. There aeems to be plenty of support for this process on Google.
I would not make it a service, what happens if you want to interrupt the announcement or make an adhoc announcement. You actually need a PA system and should probably look around for a package before attempting to build your own (this assumes you are into running the sports centre and are not a developer).

I've been a hobbyist developer for much longer than I've been working at the centre. But theyve just made me a manager, so now looking at making some cool new toys. We've got a PA system, but I want to make things as automated as possible as Im getting busy doing other things.

That's not what a service is for; and yes, the user can close services. Using services also introduces a new problem - they usually run under a system-account, and should not be messing with the users' desk.
Simplest solution; get a list of MP3's to play. Play them yourself (from code), then it becomes quite easy to interrupt the song at a predefined time and to play "something else".

Maybe a service isnt what I need. Was just a thought.
Thanks for the suggestion, I might try that out.
Also found another answer here. Only problem with that is it claims win7 and later which means finally upgrade from vista.

how to edit in crystal report
|
|
|
|
|
Reports are effectively read-only views of your data and should not be used for editing the data
=========================================================
I'm an optoholic - my glass is always half full of vodka.
=========================================================

|
|
|
|
Edit what exactly? The criteria?
Can you edit your question please, it isn't clear.
|
|
|
|
|
|
IIRC you can add comments to a report, not the same as editing which is not possible.
I might be completely wrong as I have not used that pile of crap for over a decade. One of the worst apps even inflicted on the development community.

What do you mean exactly ?
Usually you work from a template and assign data to it, either by passing parameters so the report generates itself or by passing a datasource.
So do you want to change the template or the generated report itself.
In case of the former, to do it properly you'll need the crystal reports editor application (VS is limited).
In case of the latter, please define better what you want to achieve, because that's not entirely the purpose of Crystal Reports.

i have developed a small win apps which is suppose to capture skype conversation. my main concern is that i have define the
WndProc() here is the code a bit
protected override void WndProc(ref Message m)
{
Boolean handled = false;
if (m.Msg == NativeCalls.APIAttach && (uint) m.LParam == NativeCalls.SKYPECONTROLAPI_ATTACH_SUCCESS)
{
NativeCalls.HWND_BROADCAST = m.WParam;
handled = true;
m.Result = new IntPtr(1);
}
if (m.Msg == NativeCalls.WM_COPYDATA && m.WParam == NativeCalls.HWND_BROADCAST)
{
COPYDATASTRUCT data = (COPYDATASTRUCT)Marshal.PtrToStructure(m.LParam, typeof(COPYDATASTRUCT));
StatusTextBox.Items.Add(data.lpData + Environment.NewLine);
IsCallInProgress(data.lpData);
handled = true;
m.Result = new IntPtr(1);
}
m.Result = IntPtr.Zero;
if (handled) DefWndProc(ref m); else base.WndProc(ref m);
}
but controls is not coming in this
if (m.Msg == NativeCalls.WM_COPYDATA && m.WParam == NativeCalls.HWND_BROADCAST) block that is main problem.
here i attach the link of my win application and that is https://onedrive.live.com/#cid=C4A6F16F34D7540A&id=C4A6F16F34D7540A!126 just download the skypecalltest and run it.
before run my apps just login to skype and then run my apps where you put a phone no and click on call button then you can see the controls is not coming repeatedly to the second if block.
so what i need to change in my code as a result control will come to second if block repeatedly .
in the same link there is another same kind of apps which is based on wpf and that is working where wndproc is calling repeatedly. if possible check that code too and guide me what i am missing or making mistake. thanks

Like this[^] one? 
Did the application connect to skype? Does the demo from that website work?

i develop my win apps following that application whose link you refer but that application is wpf based apps and working fine but my one is not working properly. if possible please download my apps from this link and run at your end to capture the problem. here is link from https://onedrive.live.com/#cid=C4A6F16F34D7540A&id=C4A6F16F34D7540A!126 just download the skypecalltest and run it and definitely notice that WndProc() function is calling repeatedly for getting message from Skype.

A Windows Forms application? Try running it as an admin
Tridip Bhattacharjee wrote: if possible please download my apps
I'm not going to download a complete project, especially not one that hooks into my Skype. You might want to add in some code that logs *each* WM_BROADCAST and each WM_COPYDATA going trough the WndProc; see if they get called.

you asked me to log WM_BROADCAST and each WM_COPYDATA that is the main problem because when i run my apps then controls only come to this if block only once
if (m.Msg == NativeCalls.WM_COPYDATA && m.WParam == NativeCalls.HWND_BROADCAST)
so i think if try to log WM_BROADCAST and WM_COPYDATA then only once it will be logged. any better idea?

Does it stop painting the form after that message is received?
if (handled) DefWndProc(ref m); else base.WndProc(ref m);
Why is the DefWndProc there?

i am not trying to paint my form. i am trying to receive message from skype window. if i write only
base.WndProc(ref m); then also same thing happen.

I know; Windows tries that - it's the fastest way of checking whether the handler is still processing messages.
Did you try to run it as an admin? I can imagine UAC blocking the broadcast
