Ok I know how one function can write multiple lines with \r\n but I want multiple functions writing to one edit box with no previous data being overwritten. for example I have a dialogbox with two buttons and an edit box.
When the first button is clicked:
CString S1 = "William Jefferson";
CString S2 = "Bill Clinton";
m_Multilines.Format( "%s\r\n%s", S1, S2);
UpdateData(FALSE);
And when the second button is clicked I want to display another string underneath this one but I can never do it without erasing the previous data, can someone please help me to implement this correctly?

UpdateData(TRUE);
m_Multilines += "\r\nAnother line";
UpdateData(FALSE);

I'm looking forward to it
Anyway, here's another version:
CString strx;
GetDlgItemText(IDC_EDIT1, strx):
strx += "\r\nAnother purist bites the dust";
SetDlgItemText(IDC_EDIT1, strx);

How can i create fancy dialogs as that we can see in MSN messenger. In MSN messenger various dialogs consist of property tabs/sheets. But these are not of the style of standard win32 type tabs. Instead their structure is like fancy picture. How can i achieve this ????????

Do you meant the tabs for the Options?
According to SPY++, these are a standard windows control. It is possible that they have used some custom draw techinques. Have a look here http://www.codeproject.com/tabctrl/ for more info.

No, i didn't mean the "options dialog tabs" you mentioned !!!
The correct example is that of "send file or photo" dialog.

Okay, I see the ones you mean know.
This is a pretty simple trick. According to SPY++, these are button controls and not tabs. I'm guessing it's just an ownerdraw bitmap button with maybe use of the RGN GDI stuff to shape the button. I'm sure there must be an article on CodeProject which shows how to do this.
Clicking the buttons must just hide one set of controls and show the others.

Hi an need to spy on a text window that is displaying strings. Everytime this window displays new text i need to retrieve the new text and save it to a database in my app. I suppose i need to set up a hook to accomplish this?
I can get a handle to the window and when using Spy+ and when the window is displaying text the only message i can see is WM_PAINT..
How can i get the text beeing displayed in the window? Dont want all text in the window, just the latest string that was displayed.

This text window is in your process or in some other process?

It's in a different process, a different application that i don't have the source to...
So im not sure it's possible to do what i want, but maybe i can do it with a hook?
|
|
|
|
|
OK - hook will do.

Thanks!
I'm not very familiar with hooks tho... do you have some sample code for this?
I do have a sample of a mousehook so i know where to start, but I'm not sure how to set it up so i get the text i want.. what message to spy on...
What type of hook do i need to set with SetwindowsHookEx?
|

If you plan to monitor changes in edit box, it's probably best to hook its parent and wait for EN_CHANGE notifications, which are sent through WM_COMMAND.
The hook you need is WH_CALLWNDPROC. Search MSDN for SetWindowsHookEx - there should be some examples.

How to get the applicatin path of the programm? in MFC and win32
Gaurika Wijerane
|
|
|
|
|
GetCurrentDirectory
or
GetModuleFileName
|
|
|
|
|
CString GetExePath()
{
TCHAR moduleFileName[MAX_PATH+1];
if (0 != GetModuleFileName(NULL, moduleFileName, sizeof(moduleFileName)))
{
PathRemoveFileSpec(moduleFileName);
}
return moduleFileName;
}
passing NULL to GetModuleFileName() retrieves the current module's file name, so call this from the exe rather than a dll linked to the exe. Or pass the exe's HINSTANCE to the call.

In MFC the easiest way is to use __argv[0]

I'm amumu, and you?

If I had to guess, I would say that it is because you have declared a class A template parameter in your object class, and class B in the Func1 function. This code compiles fine in VC++ 6.0.
Also, I do not think that there are many people on this forum with experience in g++.
|
|
|
|

If I comment the foo(), that's no problem.
I am confused about it, may be it is the bug of g++?

Hi,
I know that if there are several threads share a common array, i need criticalSection to protect to prevent all threads trying to WRITE to this array at the same time.
However, I just wonder if criticalSection is required to prevent all threads trying to just READ the info from this array at the same time.
Thanks!
|
|
|
|
|
It is not required, there is not a problem if everyone is just reading. However if you have some threads reading and other writing then you must protect yourself as well 
Best regards,
Alexandru Savescu

Yes, because if you don't then you run the risk of reading while someone is writing and thus the data might be suspect.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?
