I am trying to create 512 CEdit boxes with a "3D" look to them. I know I need to use CreateEx with the style WS_EX_CLIENTEDGE. My Code is below (I have this code in OnInitDialog):
CEdit *EditArray[512];
for(i=0;i<512;i++)
{
EditArray[i] = new CEdit;
EditArray[i]->CreateEx(WS_EX_CLIENTEDGE, _T(controlname), _T(""), WS_CHILD | WS_VISIBLE, CRect(topleft,bottomright), this, i+1500);
}
This code compiles and runs without a hitch...except that the textboxes are never visible. If I switch to a simple CEdit::Create it works and all the textboxes display. Please note that I have code in addition to the above which displays the textboxes in different locations (topleft & bottomright are changed for each textbox). Does anyone have any suggestions as to why I am unable to view these textboxes?

If you want CreateEx() called more than once, you should consider wrapping it with curly braces.

Right...as I said, this isn't my exact code...curly brackets have been added...back to main question...

The controlname is CString.
controlname.Format("EDIT%u", i);
So...
EDIT0
EDIT1
EDIT2
...
EDIT511

If your car doesn't work, do you send another car of the same type to the garage?
I mean, it's hard to help you if you don't provide accurate information and post something else than the code that doesn't work.

Hint: Have a look at what CreateEx() returns and if it happens to be FALSE you might want to check out what GetLastError() returns.... 
You have to use a registered window class and the names you create on the fly are not registered window classes.
Your call should look like this:
CreateEx( WS_EX_CLIENTEDGE, _T("EDIT"), _T("").....

How would I be able to use a registered window class for each of these CEdit boxes? Where/How do I register "EDIT0", "EDIT1", etc...
|
|
|
|

You really need a different CLASS for each control?
I'm curious - what are you trying to do?

I'm simply trying to make 512 Edit Controls programatically. In addition to this I would like them to be "3D" which requires the CreateEx. Other than that I'm open to any solution.

|

Ah...found my problem. If I simply use "EDIT" as the class name it works. I guess for some reason I thought I needed a new class for each Edit Control. Thank you Mark for giving me the right clues!
|
|
|
|
|
Give them different names... different IDs.... but different classes? 
Glad you got it!
Cheers,

Don't confuse a window class (EDIT) with an MFC class (CEdit).

I thought I told you that, or at least I tried with the code snippet... 
Glad it works now, but a dialog with 512 edit boxes? 
I guess I would close that window and never open it again....

You may have intended to say it, but that does not mean it got read. Go back and re-read your post. Notice anything missing, like:
"...display. Please note that I have code in addition to the above which displays the textboxes in different locations (topleft & bottomright are changed for each textbox). Does anyone have any suggestions as to why I am unable to view these textboxes?"

If David's most accurate reply doesn't help because you've posted code that's not the same as you're trying to build, then I'm curious about what's hidden behind the "controlname" identifier.
Is it really "Edit" for edit boxes, as CEdit::Create() would use, or is it a window class you've registered yourself? 
On the other hand, since you're already walking through the array of CEdit pointers and presumably calling SetWindowPos(), you could also call ModifyStyleEx() in order to add the WS_EX_CLIENTEDGE style to your controls.

I am having problem opening a file after I change the version number. I would like to add an extra variable to class... changed int Version = 6; and said if(Version >5) ar>>newVariable;
void CLineClass::Serialize(CArchive& ar)
{
if(ar.IsStoring()){
int Version= 5;
ar<<Version;
ar<<m_ChannelName<<m_IsAltered<<m_MaxNumberOfBoards<<m_LineAddress<<m_LineColor<<m_ShortChannelName<<
m_LookUpTableFilename<<m_Units<<m_DecimalPlaces<<m_Description<<m_PrivateNotes;
}
else{
int Version;
ar>>Version;
ar>>m_ChannelName>>m_IsAltered>>m_MaxNumberOfBoards>>m_LineAddress>>m_LineColor>>m_ShortChannelName>>
m_LookUpTableFilename;
if(Version>2)
ar>>m_Units;
else
m_Units=0;
if(Version>3)
ar>>m_DecimalPlaces;
if(Version>4)
ar>>m_Description>>m_PrivateNotes;
}
m_COperationArray.Serialize(ar);
m_LookUpTableArray.Serialize(ar);
}

What you've posted can be considered as "dummy code".
Dummy code only works for explaining a concept, but you've already proven the concept with "version 5".
I suggest you post the real code instead.
What you've posted doesn't even compile due to spelling errors and mismatching braces.
This is to prevent an endless loop where the rest of us find errors in the code you've posted and you go "my real code doesn't look like that". And if no error is found in the dummy code you won't know what's wrong with the real code.

I've taken the liberty to format the code above to make it more readable since you didn't use the <pre></pre> tags, which you ought to when you're posting code in the forums.
You have to verify that the serialization of all classes for the member variables works properly by using the debugger.
Step through the code in CLineClass::Serialize and see at which line it asserts.
You said you wanted to increase the version number and add a variable to be serialized. Have you tried following the pattern in the code above?
I'm unable to find any error in the code you've posted so far, but you also said that version 5 worked.
Make sure you're not trying to read a file with a higher version number than the code supports by verifying that the version number in the file is less or equal to the version number of the code.

Sorry, didn't notice the buttons....
I got it working with the same code, not exactly why it didn't work the first couple of times I tried it.
Thanks for your help

I am using a CListCtrl with 'LVS_ICON'.
In VS2003 the different icons in the ListCtrl could be selected that caused the default behaviour (Blue Selection-Box). In the newer version of the Visual Studio the Selection-Box does not appear and the icons disappear when selected.
Has anyone an idea what the problem might be?
