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!

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:
http://www.codeproject.com/buttonctrl/[^]
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..

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

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.

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
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

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

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?
|

(1) VC contains part of the Platform SDK which is necessary to develop Windows applications (without that part you couldn't do it in VC)
(2) You need a newer Platform SDK if you want to access features available in new Windows versions
(3) If you are using a different compiler, you need the paltform SDK, too.

The MFC app is "dialog based", "main window" is a CPropertySheet with 2 pages.
logic process in CWinApp::InitInstance() looks like
//-------------------------------
Hide "main window"
if(error)
{
show "main window";
display error on main dialog;
}
exit the app;
//-----------------------------
i have to hide main window first for some reasons - hard to explain why in a few sentences.
according to process above, if no error, i should see nothing.
but actually i always see the dialog in a flash.
it means main window (property sheet) has not been hidden properly and thoroughly.
do you know how to hide the dialog without seeing a flash?
thx

When you create dialog you specify its style, and one of the styles is if the window is shown or hidden. Remove shown flag. Use this if you create dialog through CDialog::Create()
If you created dialog in Resource editor then doubleclickit to change its properties, and turn off Visible property.
