Hello,
Does anyone know how to have the character limit on the editbox of a comboboxex control removed or set very big ?
Thanks
David

Use CComboBox::LimitText().

I guess you need to make your combo box hold text more than its width. You can do this by setting CBS_AUTOHSCROLL style of the combo box. You can do this by setting Auto property of combobox to true.

Sorry to say this but neither works
As a test I wrote the following to see the limits and set the good styles:
HWND hwndcombo = FindWindowEx( this->m_Hwnd, NULL, NULL, NULL );
SetWindowLong( hwndcombo, GWL_STYLE, GetWindowLong( hwndcombo, GWL_STYLE ) | CBS_AUTOHSCROLL );
int n = SendMessage( this->m_EditHwnd, EM_GETLIMITTEXT, 0, 0 );
char data[500];
wsprintf( data, "Limit : %d", n );
mIRCError( data );
SendMessage( hwndcombo, CB_LIMITTEXT, (WPARAM) 0, (LPARAM) 0 );
n = SendMessage( this->m_EditHwnd, EM_GETLIMITTEXT, 0, 0 );
wsprintf( data, "Limit : %d", n );
mIRCError( data );
Edit_LimitText( this->m_EditHwnd, 0 );
n = SendMessage( this->m_EditHwnd, EM_GETLIMITTEXT, 0, 0 );
wsprintf( data, "Limit : %d", n );
mIRCError( data );
The combo child of the comboboxex has its CBS_AUTOHSCROLL style, and the edit has its EM_AUTOHSCROLL style and the output of the above gives :
Limit : 30000
Limit : 30000
Limit : 2147483646
So the initial limit is already 30000 chars so it isn't the culprit.
I still hear the little ding sound when I get to the end of the editbox notifying I can't put more there even if the AutoHScroll style is there and the limit is way beyond the actual control limit.

Why not set this style at design time? Many styles cannot be changed at run time.

Why are you sending a message to the edit control? You should be using CComboBox::LimitText() instead?

The CB_LIMITTEXT message limits only the text the user can enter. It has no effect on any text already in the edit control when the message is sent, nor does it affect the length of the text copied to the edit control when a string in the list box is selected.

Good point, must I say that MSDN help sucks then
ComboBoxEx Control Styles
ComboBoxEx controls support only the following ComboBox styles:
CBS_SIMPLE
CBS_DROPDOWN
CBS_DROPDOWNLIST
WS_CHILD
No where does it say it supports in the CreateWindow() CBS_AUTOHSCROLL
Anyways, fixed, thanks

Hi every body

All right, I give up. There must be a trick to this.
Basically I have this gigantic workspace with projects that spits out little DLLs. Some of the basic DLLs are loaded by another DLL which is finally loaded by the executable file.
What happens when I put a breakpoint is that the Visual Studio spits out warning the breakpoint is disabled.
I already put in all the DLLs under the "additional DLL" under Debug tab in MS VC 6.0, and still no luck.
Any help is appreciated!!

Yes they are.
Thinking a little bit more about it, I dont know if this matters, but these DLLs are being copied to another directory instead of being used straight from their respective Debug directory. So instead being run from "MyProj\Debug\MyProj.dll" there is a post-build step to "copy MyProj\Debug\MyProj.dll c:\output\dlls". Thus the code loads the Dll like LoadLibrary("c:\output\dlls\MyProj.dll")

Hi-
What are the rules of MAPI programming when it comes to allocation and deallocation of memory?
Should I delete everything I allocate and everything they give me?

I need to learn the basics of working with forms. Does anyone know of any C++ source code that can show me the simple stuff?

Have you looked on this site?
http://www.codeproject.com/docview/#Form+Views[^]
Basically you need to create either an SDI or MDI application with CFormView derived view class. To add forms use the dialog resource editor and insert an IDD_FORMVIEW dialog resource. This is a child window derived from the CDialog class which is then displayed in the CFormView. In either the CMainFrame class or the CDocument class you can add a view switching handler to change from one form view to an other.

Hi there,
I want to create a simple cpp file in VC++ 6.0 then compile it using the cl command in the command prompt but I don't know what are the steps that I should do to achieve that.

Can someone please help me out?

I have an app that I want to capture images of webpages from a hidden webbrowser. An example of this is an application at www.rabidsoft.net called CaptureIT. Win32 or .net is fine for the solution if anyone has any information.

Hi all
I have a code that runs a simulation producing numeric outputs of a time series multiple times. I don't know in advance how long is the series or how many times the simulation will run (defined by user at run time). I would like to have the program to write the results out to a file in one column per simulation run instead of a single column where the result of each simulation is separated by some marker.
The code to write the output in one column would be something like this:
<code>ofstream WriteOutput(OutputData.out,ios::app)
for(sim=1; sim<=nsims; sim++)
{
for(t=1; t<=n; t++)
{
y=f(x[t]);
WriteOutput >> y >> endl;
if(t==n) WriteOutput >> "#" >> endl;
}
}</code>
This produces an output like this:
3
4
5
6
#
4
5
6
7
#
Instead, I'd like a code to write an output such as:
3 4
4 5
5 6
6 7
How can I do this?
Thanks!
C.

Yeah that works... I was wondering if there was a direct way to format the output in columns.
Thanks!

If you are not worried about portability issues, you can use SetConsoleCursorPosition

Can you explain? Portability? How do you use SetConsoleCursurPosition? I'm writing to a file not sending out to console.
Thanks

Oops, ignore my post then

the endl that you are outputting after every number is what causes the newline to be output. Just control when you output an endl.

Hi,
So far, I did it by setting the initial dir to be C:\ and then sending a virtual click to "Up One Level" button. Do we have any better ways to do that? I think it should have some special string so that CFileDialog could understand and start the dialog with "My Computer" as its initial directory. Unfortunately, I've not found it yet! Please help me.
Thanks in advance.
