There is no ActiveX control.
yea I am calling AfxEnableControlContainer() in InitInstance();
|
|
|
|
|
Any custom controls ? If yes, check that the class name is correct.

There is no custom control.
Actually this project is running in other computer (WIN2000,XP).
But not mine.So there is no bugs in coding.

Did you use of CRichEditCtrl Class on your program?
|
|
|
|
|
No...CRichEditCtrl is used...
I have just create a new dialog based project named "VMCGScannerAppSuite".
Then just build and run the project...No control is used this project...
I am little bit worried about this type of problem. Some previous projects have the same problem which was okay some day before and some of them running well.

Hi.
I have created a MDI with CFormview. I also have created a form in which I want to call from the menu. How do I call this form?
|

Hi.
Sorry if I didn't state the problem clearly. I have a similar problem.
I created MDI derived from CFormview. Now, I want to have a new view which I have managed to create by Insert -> Resource -> Dialog -> IDD_FORMVIEW. I have changed the ID to IDD_GRAPH.
MDI created 2 menus called IDR_MAINFRAME and IDR_CVTYPE. I have modified IDR_CVTYPE to create another menu entry called 'View'. Under 'View', there is a submenu called 'Graph'. When the user click 'Graph', I want a child window to open with the new view (IDD_GRAPH). The problem is what should I code for the new view (IDD_GRAPH) to open when 'Graph' is clicked?

Hi,
have you read the links I gave you??? I have there posted how to create/open/manage the new views.
I have a CScrollView to have the project, and when the user makes double click in one element. It then comes the new CFormView in another window to allow the entry of advanced parameters for this concrete element. I have 4 templates (1 CScroll, and 3 different CFormViews) but up to 48 new windows are possible (one per each possible element).
Take a look on the code of function "CreateOrActivateFrame ()". This is what I use to open or set focus to an already opened "secondary" view.
Greetings.

Would you mind shortening this code ? specific to your "exact" probelm.

Do you really expect anyone to wade through all of this code? Post only the relevant portion, which is usually less than a dozen lines.

A Class To Read from Text File(.txt) and Write to New Table in Design Visual C++

Sounds like a good header for an article on iostreams. It's obviously not a question, so what is it ?

Ok.
1) How to read data in text file and
2) Write data to new table(this table is create or design in Visual C++ form)
I want coding to read and write in Visual C++
|
|
|
|
|
To Read Data, use CFile or CStdioFile class.
For more information try msdn library.
Importing it into your own designed table completely depends on the way you have designed the table.

To read data, use ifstream whenever possible.
Depends what you mean by table, in a database ? Then it depends on how you're getting DB access.

What does the following code do?????????
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

if _DEBUG has been defined elsewhre, it defeines DEBUG_NEW and undefines THIS_FILE, then sets it to the current file namae. It's not C++, it's nasty C preprocessor stuff. Avoid if you can.
