Can you please tell me what's wrong with this code:
CMyRichEditView *pView;
CRichEditCtrl& pCtrl = pView->GetRichEditCtrl();
pCtrl.ReplaceSel("\r\r\ntest");
I get a debug assertion in the third line.
thanks

I've never used a RichEditCtrl before, so I might be wrong, but it looks like you're declaring a pointer and never constructing it, so pCtrl is probably NULL or invalid somehow. Something like that

Yes, it seems to be NULL, by why? 
|
|
|
|
|
If you have a Assertion is because your code didn get the RichEditCtrl.
In others words pCtrl is NULL.
Do you really have the view of the richedit?
Best Regards!!!

That's a good question.
I thought this is the correct way to get the CRichEditCtrl of a CRichEditView.
|
|
|
|
|
How you get the view of the richEdit?
You made something like this?
CRichEditCtrlView* pView = (CRichEditCtrlView*)GetDlgItem(IDC_RICHCTRL);
I saw taht you get the view from a derived class or from your own class of RichEditView I think that the problem start there....

NO, the other way round 
I want to get the control from my SDI-application, which has a CRichEditView class
|
|
|
|
|
Have a look at the Wordpad example and all your problems will be solved.
Question: What does pView point to????????
Exactly so how can you call GetRichEditControl?
|
|
|
|
|
I think this is the problem.
pView points into nothing 
I changed the code to
CMyRichEditFTPView *pView = (CBMyRichEditDoc*)GetView();
CRichEditCtrl& pCtrl = pView->GetRichEditCtrl();
pCtrl.ReplaceSel("\r\r\nTest");
But the compiler says that GetView() ist an undefined expression (or something like that, I have the german visual c++), although it is defined in the MSDN as follows:
CRichEditDoc::GetView
I'm totally confused now
|
|
|
|
|
You are a little confussed.
The getView is for get a view pointer from the RichEditDoc.
Please read how you can get a good view from a RichEdit Using the GetDlgItem function. I put an answer before.
After that you can get a pointer to the CRichEditCtrlCtrl
Regards!!!

In what class is this code?
|
|
|
|
|
It is in the MainFrame class of my SDI appliction, and all I want to do is to insert a line into the CRichEditView
|
|
|
|
|
does anybody know why it doesnt work?
CString str;
str = "c:\\test.bmp";
SystemParametersInfo(SPI_SETDESKWALLPAPER,0,str,SPIF_UPDATEINIFILE);
but the following works:
SystemParametersInfo(SPI_SETDESKWALLPAPER,0,"c:\\test.bmp",SPIF_UPDATEINIFILE);
pleaze help!!!!
|
|
|
|
|
|
I get this error:
error C2664: 'SystemParametersInfoA' : cannot convert parameter 3 from 'class CString' to 'void *'
|
|
|
|
|
1) Next time you post a question make clear that you have compiler error
2) The error message is self-describing. 3rd parameter to SystemParametersInfo is void *. You can't directly pass CString object as void *. You need to cast like this:
SystemParametersInfo(
SPI_SETDESKWALLPAPER,
0,
(void *)(const char*)strWallpaperFile,
TRUE);

Hi,
almost every one of my programs uses an ini-file.
I have written a class that scans the file at program start and stores all variables in a global dynamically allocated struct.
Because this takes some memory when the program gets larger, I was wondering if scanning the file for a particular entry when it is actually needed wouldn't be the better alternative.
What is the 'proper' way to use ini-files and why?

Hi,
I don't want to start a flame war here, but since I'm not using MFC and most of my programs don't have a big GUI, I find it too much a bother to write an options dialog, etc. everytime.
-Sebastian

While the discussion on reading ini at startup versus on-demand would be interesting, I think you should ask yourself if it's worth the trouble. How much memory are you using for this global struct?

Hi,
its not very much for a smaller program, but I was wondering if I should really store every minor option like background colors, switches for controls or windows the whole time the program is running.
Thanks for your time.

Assume that it's biggest program you're ever going to write. Multiply the struct size by 4. How much memory are you going to allocate?

OK, you're right, it won't use up all my RAM. But is it really good programming practice to have all these unused variables lying around all the time?
-Sebastian

Good programming practice is to spend your development time on issues that really matter. I don't believe that loading ini settings at startup can hurt you or your performance. If it works for you, leave it, unless you have nothing else to do (in this case, it's better idea to go for some beer).

It's simply a matter of what is prudent within the context of the program's architecture. I think almost all of my programs do it that way (loading the ini data into a struct or object).
There is no "proper" way to do it really beyond obeying the laws of C++ physics.
