additionally, there's another simple way to do it...

Convert the string to a global atom: GlobalAddAtom
ATOM GlobalAddAtom( LPCTSTR lpString );

this converts the string to a handle -- which you can transmit via Post/Send Message to any other process. Use GlobalGetAtomName() on the other end to convert it back.

It's a simple way to send small strings (255 chars or less).

Minimum pane size in a CSplitterWnd

Hello all,

I am using a CSplitterWnd. I would like to prevent the user from dragging
the splitter any closer than a certain distance from the edge of the window.
I found that CSplitterWnd::SetRowInfo() and CSplitterWnd::SetColInfo() allow
you to set a "minimum" size. However, it's not the case that the user can't
drag the splitter past this minimum. It's just that if he does so drag the
splitter, the window size will become 0.

Is there a way to do what I wish and pysically disallow the splitter to move
past a certain point?

Thanks,
Jitendra

I'm wrote a simple code to creates a empty Dialog. But I've an exception with him. Why?

    DLGTEMPLATE dlg;
dlg.x = 0;
dlg.y = 0;
dlg.cx = 200;
dlg.cy = 200;
dlg.style = WS_BORDER|WS_CHILD|WS_VISIBLE;
dlg.dwExtendedStyle = 0;
dlg.cdit = 0;

Dialog.InitModalIndirect(&dlg);
DoModal();

From MSDN: "To create a modal dialog box indirectly, first allocate a global block of memory and fill it with the dialog box template. Then call the empty CDialog constructor to construct the dialog-box object. Next, call InitModalIndirect to store your handle to the in-memory dialog-box template."

Here is the most IMPORTANT part:
"first allocate a global block of memory"

It does not matter which version of InitModalIndirect you call, the DLGTEMPLATE must be in a globaly allocated memory block. That means using GlobalAlloc(...).

If this is not the cause of exception, then the MSDN remarks section may be wrong.

The only question that remains is: who is responsible for freeing the memeory?

Search the MSDN for the sample code:
"DLGTEMPL: Creating Dialog Templates Dynamically"

Good Luck!

How to have bitmaps in lib

I'm creating a library with som custom controls. How can I have a bitmap drawn on a custom button?

When the button control is in a .lib - where to put the image?

What about resource conflicts?

Thanks for any comment

Put them in a DLL or ActiveX library, both types of libraries have there own resources. Their resources can not conflict with your resources, unless the DLL treats externaly supplied resource IDs the same as internaly supplied IDs.

For buttons:

For libraries visit the COM or Libraries section of codeproject.

To make it simple, I made this small utility that converts a binary file into an array of unsigned chars for the compiler to read. This enables me to #include the binary chunk directly into the source.

Wooh, does this smell like good old times..

SQLBulkOperations returns SQL_NEED_DATA with Oracle

Hi,

I'm using SQLBulkOperations(m_hstmt,SQL_ADD) in one of my methods when trying to bulk copy a table from one db to another.
It was tested and worked fine for copying from Oracle to mdb, but when trying to copy from mdb to oracle or oracle to oracle I get SQL_NEED_DATA.
I checked over and over and the code seems fine to me (buffers were created and assigned). The SQLBulkOperation call looks like these:

ODBC_CALL(::SQLSetStmtAttr(m_hstmt, SQL_ATTR_ROW_ARRAY_SIZE, (void*)wRow, 0));
if(!Check(nRetCode)){
}
ODBC_CALL(::SQLBulkOperations(m_hstmt,SQL_ADD));

Can anyone help ?
Thanks

Color for the Tree Control Item

Hello Friends,
I am using CFormView on which I have a combo box and a Tree Control. When any item is being inserted depending upon some boolean variable the color for the item should be either red or black.

For example;

bool valid = false;

if(valid)
treecontrol item text color = red;
else
treecontrol item text color = black;

I am not using CTreeView, but I have CFormView on which they are two controls.
I am not able to set the color for the individual items.
Please help regarding the above matter.
Thanks in Advance.

Thats because there are no options to set individual display properties, both for the Tree Control and the List Control.
If you need such control, have a look at using Custom Drawing. Take a look at this[^] and this[^] to start.

Problem with IHTMLDocument2

I am trying to implement a web page filter. I define the invoke method and pass the IE events to my application thanks to the Advise method. It works well but I can only obtain the content of the current page when the DOCUMENTCOMPLETE event is triggered. I would like to have it when the BEFORENAVIGATE2 event is triggered to prevent some pages from displaying. It would also fit to tell IE to wait until a page is completely download before displaying it. I am trying to get the HTML content of a web page before IE starts displaying it. I don't know how to do it.

Thanks for your help.

EDIT CONTROL looses the connection

EDIT CONTROL looses the connection
Hi,

I am currently working on a program in VISUAL C ++ 6.0 (MFC) in which I would like to include an ADO DATA CONTROL 6.0 and a MS MASKED EDIT CONTROL.
The EDIT CONTROL is connected with the DATA CONTROL after program start-up.
All desired fields are indicated with the EDIT CONTROL.
Should the RECORDS SOURCE of the DATA Controls be changed or be limited during the runtime , the EDIT CONTROL looses the connection to the DATA CONTROL.
I have already tried everything REFRESH ()..., BindDefaultProperty or BindProperty, unfortunately, without success.
I could not find a Solution to this problem or topic even in the Internet.
I would be thankful for a hint or for your assistance.

thanks

How to make a ClistCtrl has a gridline look?

I'm sure it involve LVS_EX_GRIDLINES attribute.
but ClistCtrl::SetExtendedStyle(LVS_EX_GRIDLINES | LVS_REPORT);
didn't work! Smile | :)

Re: How to make a ClistCtrl has a gridline look?

mirex1-Dec-04 5:10

mirex

1-Dec-04 5:10

maybe LVS_REPORT has to be set through

ClistCtrl::SetStyle( LVS_REPORT );

and then try setting

ClistCtrl::SetExtendedStyle( GetExtendedStyle() | LVS_EX_GRIDLINES );

i think that LVS_EX_... means Extended style, and can be set only through SetExtendedStyle()

CAB project in Visual Studio .NET (Simple Q)

anderslundsgard30-Nov-04 21:46

30-Nov-04 21:46

If you ever dealt with CAB-project this might be an easy question.

I’ve created a CAB-project and added an .ocx (ActiveX). When adding the CAB to my webpage the ActiveX will be registered and works good.

The problem is that my .ocx now uses a .dll that I also want to be registered so it can be used properly.
When I’m adding the .dll to the CAB-project that already contains my .ocx it doesn’t become registered when users loads my CAB. (The .ocx is still registered accurately.)

How do I make One CAB-file and force all it’s containing files (dll’s and ocx’s) to be registered?

When I make a new CAB-project and only adds the .dll it is registered as it should be.

In the Open File common dialog, is it possible to modify the "places" bar (the list where Desktop, My Files, Network environment etc. are displayed)

Our software offers standard locations for certain file types, which I'd like to put there.

This might be a stupid quistion for experienced developers, but is confusing me to much;

What is SDK? why it exists (any special reason)? why it is needed?

After some search on SDK, I have come to know that it is a s/w application /tool that allows to do low level API programming, here is the confusion i.e. when all APIs can be called in VC then why one should go for an SDK?
