I can change the button image. My problem is button should not call any event. But it is calling button clicked event even it is disabled.

are you sure that the m_btnVerify is the same that you want to disable and also check that the conditions are met for disabling. You must be enabling the button later some where in your code. Otherwise do you mean that the button does not appear to be disabled. if yes that may be because of the bitmap that is displayed on it.
Somethings seem HARD to do, until we know how to do them.

Since its a bitmap button, you should provide the bitmap to be displayed when the button is disabled. If its not provided, the main button bitmap will be displayed. I suggest you to check your call to CBitmapButton::LoadBitmaps() function.

Use the HtmlHelp function instead of ShellExecute, it takes care of that.

const char* help_file_path = "help.chm";
HWND hwnd = AfxGetMainWnd()->GetSafeHwnd();
const char* topic = NULL;
HtmlHelp(hwnd, help_file_path, HH_DISPLAY_TOPIC, (DWORD) topic);
You have to include htmlhelp.h and link with htmlhelp.lib, you'll find them inside the directory of your html workshop, for example "c:\Program Files\HTML Help Workshop"

Hi ,
Basically I work on Lotus Notes, and I am a newbie on Visual C++. As of now, I need to access Lotus Notes Dbs and using Notes C++ API toolkit for Lotus Notes. I have set the environment including PATH , Include and LIB variables. I tried compiling my program （MFC/Dialog）. However, its giving me the following compilation errors :
error C2065: 'LNNotesSession' : undeclared identifier
Moreover I have set like this:
#include <lncppapi.h>
龍

Did you include "LNCPPAPI.H" header?
I found it from here - http://www.taupo.co.uk/examples.html[^]. BTW, Google is your best friend.
Regards,
Jijo.

Hi all, I've written a c++ program that will grab images from camera and will analyze them. it's a kind of some image processing software. but here i want my network users see the result too. one solution is c++ socket programming, I mean i can write a program in c++ that will connect to my image processing server and will get images on the network.
My question is, is it possible for the users to see the results on the internet explorer and not with an additional c++ software? May be a flash module or something that will read stream from server.
Any suggestion?

Hi,
You have to subclass the tab control in CPropertySheet. Use CPropertySheet::GetTabControl API to get the tab control in property sheet. Then override the CTabCtrl::DrawItem.
Please refer here[^] and here also[^]for more information.
Hope this will help you.
Regards,
Paresh.

I'm using a CFtpConnection to transfer files from my application to a vendor's device. Sometimes, for no apparent reason, the PutFile() pauses (the vendor's device status shows a file transfer in process, but the PutFile() never returns).
Now here's the rub. If I'm in the debugger, and I break the execution, the transfers all work like a champ, and never fail. If I let the code free-run, the freeze occurs.
The "PutFile()" function is called from a separate thread than the CFtpConnection is created in so that I can detect this "hung" condition. The master thread even includes code to try and re-connect to the vendor's device - but the retry only works IF I BREAK execution in the debugger.
The "reconnected" PutFiles always work - always.
If I break the thread prior to creating the CFTPConnection, and then step through the creation, the putfiles always work.
Apparently I'm not initializing something properly in my create FTP connection (or my system in general).
I don't have to deal with WSAStartup and WSACleanup, do I?
Logic looks like this:
{
xferBlock.file_list=createListofFilesToSend( some_location );
xferBlock.pConnect=MakeFTPConnection( sIPAdress, sUser, sPassword, nError );
pThread=AfxBeginThread( AsyncPutFile, this, THREAD_PRIORITY_NORMAL,0, CREATE_SUSPENDED);
pThread->m_bAutoDelete=false;
pThread->ResumeThread();
// loop until done or timed out
do{
UpdateProgressFromxferBlockInfo();
}while( !isTimedOut() && !isDoneAccordingToxferBlock() );
// if timed out...kill progress....
if( isTimedOut() )
KillTheThread( pThread );
}
AsyncPutFile() basically loops through the file_list and does a pConnect->PutFile() on each member.
Not shown are the retry logic, which fails. But if I find out why it's pausing, maybe the retry logic won't fail?
Any ideas?

I have an MFC ActiveX ControlWizard generated project!
Need to create thread in the project.
I know in a MFC project use ::CreateThread will cause memory leaks! Instead should use ::AfxBeginThread.
But how about _beginthread ?
|
|
|
|
|
If you're planning to use MFC from the thread AfxBeginThread should be used.

Do you mean I MUST NOT use _beginthread in a MFC AppWizard(dll) or MFC Activex ControlWizard project, Do I misunstand your meaning?
And there is also an existing MFC OCX project, using too much _beginthread.
Does it occur memory leaks? And MUST I substitute _beginthread to ::AfxBeginThread?

Only if the thread being created uses MFC classes.

I can't seem to figure out why I am not able to hide/show a group box of Edit controls, I can do it for the edit boxes, but what I wanna do is hide/show the whole group box including its border and text name????? Any ideas?
|
|
|
|

Make sure the group box has a unique identifier. You can then use one of the various methods to determine the group box control and show/hide it.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

use
m_gp;//group box variable.
m_gp.ShowWindow(FALSE);//hide
m_gp.ShowWindow(TRUE);//show
same for other variable.
