do u use loop, i.e. while(), for() somewhere? if yes, check them first.

Nope. I don't do absolutely anything with that window besides creating it and updating the theApp.m_lastTilesetRect on move & size. No loops in that either.

HideCaret(hwndEdit) function was just what I was looking for...The problem of the text still being selected still remains. Also if I double click on the edit box select some text and then move around the mouse then the whole thing just gets distorted...Am I doing the right thing by using and edit control to display a text file. Is there another more efficient approach to this matter?
|
|
|
|
|
i may offer some advices but what is u really want?
an edit control on dialog box with read-only (not by style), no selection etc?
includeh10
|
|

|

Yes, that's exactly what I want. I want basically a control on a dialog which looks and behaves like a list box which does not allow selections. So I figure the edit box is the best way to go about this. From the resource editor I chose multiline/vscroll/read-only. Displays the text file just fine except for when it starts up where everthing is highlighted. The only other problem is that if you start dragging the mouse all over the control then the text gets distorted...maybe I should process mouse messages? So basically that's it. The main problem them is the the text being selected. The HideCaret() function was very nice. Thanks for your help.

basic solution needs 1 second.
if u have more than 2 controls on dialog, extra one may be any except CStatic. goto resource edit, from menu tool(?) then select TAB order, change the edit control not as first. that is all.
but the edit is light-gray. for high level solution, u need to override the edit to handle message.

That was a great idead, even though my dialog is filled up by just one huge edit control. But I made one more, put it behind the main one, made it invisible and gave it a TAB Stop of 1. Than I subclassed the edit control so as to not be able to accept WM_LBUTTONDOWN messages and that was all. Now the caret doesn't show and most importantly the text is NEVER highlighted. Maybe this isn't the best way to go about things but if it works...why not...thanks so much for your time.

hi,
the usage of CCriticalSection, several threads try lock(), unlock() the CCriticalSection object.
i want to know whether the lock(), unlock() action be atomic operation.
i think it is not a atomic operation, right?
if so, does anyone know the mechanism inside object able to prevent any interrupt to the object during one thread locking/unlocking the object?
thanks,
jim

|

If it wasn't atomic what would be the point of it? The purpose of CCriticalSection is for thread synchronization, so I would guess that it would be an atomic operation to lock/unlock the object.
I would guess that the mechanisms in order to make that happen are done at the opreating system level, but other than that I have no clue.

Was wondering whether it is possible to view normal function names in a .c file in the Workspace pane.
The function is not a class.
Codewright has this feature.
Thanks.

You have them, under the "Global" folder.

I just opened the *.c file without loading any *.dsp or *.dsw.
Any pointers how to load the global folder?
Thanks.

I have a property sheet. Before I changed anything, the default push button used to be the OK button.
Then I added three pushbutton controls the the property page. Now the first button I added has become the default pushbutton. In the UI, "Default Pushbutton" is not checked, however, running Spy++ confirms that this button is indeed being set to be the default pushbutton.
Why is that? How does MFC select which button it will use as the default? How do I change it back so that the OK button is the default?

Thats strange, because I had the exact opposite experience. I had to override several functions before I could get it to stop being the default button. You can try this tho:
In your CPropertyPage derived class override the OnInitDialog() function. Then include something like this in it:
<br />
BOOL CYourClass::OnInitDialog() {<br />
BOOL nRet = CPropertyPage::OnInitDialog();
SetDefID(IDOK);
return nRet;<br />
}<br />
I think it will work else where in your code too. Like in response to an update UI message would be a good place i think.

Would anyone tell me whether i can use CArray and CTypePtrList toghether? Are they conflicted to each other in Serialize function?
Thanks

What do you mean by using them together?

Do you know of any free tool which I can use to view my memory while I play with it...???
VC++ 6.0 memory window isn't cutting it...
I'm trying to watch char's get added and deleted and the memory view pane in byte hex mode just isn't working.

Hello,
I am using VC++ 7.0 and I am having some trouble. I am trying to build a solution with multiple projects. All but one of the projects is set to produce a .lib (Configuration Type) as opposed to an .exe or .dll etc.
Some of the projects depend on and use functions from others.
The problem I am having is this:
Visual Studio seems to be automatically inserting library files into the (presumably lib) command line arguments that I did not specify. In other words, when I open the project fresh, those libraries do not appear in the command line. But then when I build, they suddenly appear.
The result seems to be that I am inundated with many of the warning LNK4006.
Has anyone had this problem or know what I am doing incorrectly?
Thanks
John

I try to write the LF(#10) char to a file using putc() but it automatically add the CR(#13) before LF. Is there anyway write only the LF char? Thanks.

|

Try open the file in binary mode...
Just an idea.

I recently loaded Visual.net 7.0. I had been running an earlier version on another machine. I am now getting the following error message, the name of the program is CorpStrat.exe
'CorpStrat.exe': Loaded 'C:\CorpStratRes\CS2\Debug\CorpStrat.exe',
Symbols loaded.
'CorpStrat.exe': Loaded 'C:\WINNT\system32\NTDLL.DLL', Cannot find or
open a required DBG file.
'CorpStrat.exe': Loaded 'C:\WINNT\system32\KERNEL32.DLL', Cannot find or
open a required DBG file.
The program '[1812] CorpStrat.exe: Native' has exited with code 1 (0x1).
I am at a loss here. Any suggestions?
