Re: facing problem on Listing files in List box Control

20-Jan-09 1:21

Do you mean that you run a loop looking for the files, when you find one you add the path to the list, but the list only gets redrawn once your loop is done thus all your hits appear at once? If so, you have 3 options i can think of right now:
1. do the search in a different thread and send/post your hits towards the GUI thread
2. do your search with a timer
3. do your search in idle-time (when your GUI thread has no messages to process)

p.s: You could also try simply forcing your list to be redrawn in your loop with e.g. using RedrawWindow, but that would be an ugly solution.

Thanks for your reply. Yes, I have used it in loop, that's why the problem arise

Another option you can do is within your loop, when you find a file you are most likely doing

m_ListBox->AddString(xxxx)

Immediately after you do the AddString, you can add

m_ListBox->UpdateWindow()

and that will cause the list box to show the new data.

Hope that helps.

Hi,
I want to launch outlook using ShellExecuteEx and I am able to launch it. But I want to pass file (mydoc.doc) as a parameter to it. So that it will open an outlook evelop and attach this file to it.

SHELLEXECUTEINFO shExecInfo;
shExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);

shExecInfo.fMask = NULL;
shExecInfo.hwnd = NULL;
shExecInfo.lpVerb = NULL;
shExecInfo.lpFile = "OutLook";
shExecInfo.lpParameters = "C:\\test\\mydoc.doc";
shExecInfo.lpDirectory = NULL;
shExecInfo.nShow = SW_MAXIMIZE;
shExecInfo.hInstApp = NULL;
ShellExecuteEx(&shExecInfo);

Please let me know what wrong with this code.

Thanks

SNI

Does it work if you simply run outlook with a doc parameter from a console or using RUN in start menu? Maybe you need to specify other parameters to let Outlook know what you want it to do with that doc.

Thanks for reply. But I tried with other parameters but it is failing and giving following msg
"The command line argument is not valid. Verify the switch you are using." Is there any switch needs to be provided while specifying the file name.

Check out here[^], it says, the command line argument for attaching a file is /a <path to file>

Custom cursor with Win32

Hi,

I would like to make it so that when the cursor is over my window it has a custom look. How can I achieve this with win32?

Thanks,

Steve

One way is to handle the WM_SETCURSOR[^] message. A different way would be to specify your own cursor handle when registering a window class.[^].

MSDN has an interesting set of "Using xxxx" series. If interested type in "Using" into the index edit box and you'll see a bunch of articles.

As per google, MTU(Maximum transmission unit) can have maximum value of 1500 bytes but I am sending more then 1500 bytes data over socket from one application to other(on differnet m/c).It is going fine. I have tried up to 3500 bytes.
Please tell that what is the maximum size of MTU and how can I find out?

Thanks in advance.

The MTU effects only packet size. You can use send specifying bigger buffers as the MTU, but -i belive it's TCP's job- TCP will cut your data into ~MTU sized packets, send that over, and the receiver side will put the fragments together to "recreate" your data. Or am i missing the point here?

I am trying to send 3500 byts.On the receiver side,I have not implemented the code to take care of fragmented packets.So both client and server application have not functionality to deal with fragmented packets.
Without this,I am able to send and receive more then 1500bytes but as per MTU,it should not get more then 1500 bytes.
So there is lot of confustion related to MTU? In which case it is linked to TCP/IP send/receive size.
