Hi,
I'm sure there is a easy method for this, but I cannot see for looking !
Q. Is there any method to force the Nonclient area of a window to be redrawn/recalculated ?
The only methods I can see, affect the client area of a windows.
At the moment I am increasing the size of the windows then reseting it back to the original size.
My other solution was to recreate the window.
Both of thse solutions work, but they are obviously work-arounds, and I would like a more "professional"
solution.
Thanks,
Gary Ranson.

Call RedrawWindow with RDW_FRAME.

Now I am developing a tool to simulate user input (keyboard and mouse input) to other applications on windows. The problem seems to be the program doest not work like I expected when I use SendMessage or PostMessage to send keyboard and mouse input to other applications. For example, the user input steps are: mouseclick an editbox in an application’s window, type a string , and then mouseclick another editbox in the window , type another string ; First I send a mouse message to the first edit box to get focus, and send keyboard messages to type the string in the first edit box, then send a mouse message to the second edit box to get focus, and send keyboard messages to type the string in the second edit box. But the result is not what I expected. What’s the matter at all? And if I post a mouse message to click a button, then open a model dialog, but I send any message to the controls in the dialog box , nothing happed. I expect my program can work like some testing tools, such as QARun, Robot etc., to control applications and simulate user input. How should I do? Can you give me some suggestion? Thank you very much!
waiting for your help ^_^

look at keybd_event() and its brother mouse_event()

Thanks for your help! I have just solved my problem by using mouse_event() and keybd_event(),instead of using SendMessage(). The program works as i expected.

Our test team are developing a tool like QARun & Robot. You may ask me why we develop our own tool and do not use the professional tools. My manager thinks these tools can not help us to run testing well. He wants the new tool can get every GUI object's information easily on windows, and can accomplish the keyword-driven framwork well. Now the problem we meet is: we can not control the be-tested software well by using a series of keybd_event() and mouse_event(). I need the tool can simulate user inputs just like we do manually. Can you give me some advice?
thanks,
xia

Can two applications (running on two or same machine) broadcast data on the same multicast group? If yes, how is the message integrity preserved - i mean like messages getting intertwined ( part of msg1 .. part of msg2 .. rest of msg1 etc...)

Yes.

Not. Multicast is UDP, which by the very definition is unreliable.

That won't happen. You can get a complete message, a partial message (f.ex. if you exceed MTU) or no message from recvfrom(). Messages never get "blended" like this.

Thanks for the answer. I am not worried about partial messages or lost messages or partially lost messages. "Blending" was the only thing I was bothered about.
Thank you very much

Guys, I've problem reading binary files using the following code. It works text/wri. Can you guys spot an error in this? Specifically, the pBuf in the code loads 0 or null after a certain number of loops even though the file huge.
void MyClass::Read(CString sFilename)
{
BYTE *pBuf = new BYTE[4096];
CFile pFile (sFilename, CFile::modeRead); //tried
//CFile::typeBinary too
int iReadSize = 0;
while(true){
iReadSize = pFile.Read(pBuf, 4096);
if(iReadSize == 0)
break;
else{
//my processing goes here
}
}
pFile.Close();
}
Any ideas?
Thanks.

So, Papa, how do I make sure the end of file has been reached? Still from the number of bytes returned from reading, right? But, my problem is that my buffer reads and loads "" into it..more likely, it loads nothing in the buffer.
void MyClass::Read(CString sFilename)
{
BYTE *pBuf = new BYTE[4096];
CFile pFile (sFilename, CFile::modeRead); //tried
//CFile::typeBinary too
int iReadSize = 0;
while(true){
iReadSize = pFile.Read(pBuf, 4096);
if(iReadSize == 0)
break;
else{
//my processing goes here
}
}
pFile.Close();
}
Thanks,
JJ

it does read, and fill the right values, but the prob is if u try to output it using a messagebox for instance it wont show cos the chars ur trying to print aint printable !
U can see an ascii table for more info

What sort of file are you reading. If it is an exe, dll etc. then it is highly likely you'll find lot's of 0's in the file. Or are you saying that iReadSize coming back with 0 before the end of the file?

Hi,
You're right. The number of bytes returned from reading is ZERO before end of file has been reached.
When I check the pBuf, it has loaded "" into it..more likely, it loads nothing in the buffer. That's why it returns ZERO bytes. But this works for text/wri files though.
void MyClass::Read(CString sFilename)
{
BYTE *pBuf = new BYTE[4096];
CFile pFile (sFilename, CFile::modeRead); //tried
//CFile::typeBinary too
int iReadSize = 0;
while(true){
iReadSize = pFile.Read(pBuf, 4096);
if(iReadSize == 0)
break;
else{
//my processing goes here
}
}
pFile.Close();
}
Your thoughts on this will be very appreciated.

Is this happening if you specify: CFile::typeBinary, because it shouldn't. Have you wrapped the Read in a try/catch block to see if an exception is being raised. This is what the VC++ docs suggest you do.

Hmmm, I'll try the try/catch thing and keep you posted. Yes, I did specify typeBinary. I'll check the MSDN website where I hog 24/7 for info. You're the only one who understood the problem right, you know.
Thanks for the input...catch you soon.

I believe your process code is setting pBuf = 0 at some point. That's why you get the ASSERT.

Hi Todd,
That's not the case though. The number of bytes returned from Read(pbuf, 4095) is zero after couple of loops. Just this is only a problem for txt/wri files.
Thanks if you can help.

I know that this is probably a very obvious solution but I'm just not getting anywhere with it. I tried setting the m_pszHelpFilePath to point to my chm file but I then get a blah.chm is not a windows help file or file is corupted error message. If I double click on the .chm file, it opens without any problems.
Does anyone know what I'm doing wrong?

The online help in MFC uses WinHelp format (.hlp) files. Using the HTML help (.chm) requires more coding - you need to replace cals to WinHelp API with calls to HTMLHelp API.
You can find an example here[^].

I downloaded the sample at the link you gave, and its missing
#include "htmlhelp.h"
No such file exists. I thought maybe its a windows file, but I dont have one on my machine. Any ideas?
Thanks,
