How do I start programming a Visual Basic Add-In? I tried the following:
#import "C:\\Program Files\\Microsoft Visual Basic\\VB98\\VB6EXT.OLB"
The compiler failed when it tried to define the 'CommandBarsPtr' type.
Any ideas?
Thanks in advance

I'm wondering if it's at all possible to determine the hard drive location of a program from within that program. Any help would be greatly appreciated!

Greetings,
I am trying to get the length of the avi source file, and to play it in the time line at that length,
but for some reason I am always getting a "0" returned for the media length. Any suggestions on how
to retreive these?
I am under Windows 2000, and I am using directx 8.0 sdk with visual C++ 6.0.
The code I am having trouble with is marked below as "// PROBLEM AREA!!!!"
// ------------------------------------------------------------------
// Code from Directx 8.0 sdk help file.
// <article:> (Constructing a Timeline)

void main( void )
{
// Start by making an empty timeline.
IAMTimeline *pTL = NULL;
CoInitialize(NULL);
CoCreateInstance(CLSID_AMTimeline, NULL, CLSCTX_INPROC_SERVER,
IID_IAMTimeline, (void**)&pTL);
// GROUP: Add a video group to the timeline.
IAMTimelineGroup *pGroup = NULL;
IAMTimelineObj *pGroupObj = NULL;
pTL->CreateEmptyNode(&pGroupObj, TIMELINE_MAJOR_TYPE_GROUP);
pGroupObj->QueryInterface(IID_IAMTimelineGroup, (void **)&pGroup);
// Set the group media type.
AM_MEDIA_TYPE mtGroup;
ZeroMemory(&mtGroup, sizeof(AM_MEDIA_TYPE));
mtGroup.majortype = MEDIATYPE_Video;

Hello,
How can one remove the scrollbars from a CFormView based app? I've spent way too many hours trying to figure this one out.
I've tried ModifyStyle(WS_HSCROLL | WS_VSCROLL, 0);
I've tried cs.style = ~WS_HSCROLL | ~WS_VSCROLL;
This should be simple, and its driving me crazy!!!
Thanks!
Frank

In your OnInitialUpdate() function, add this code:
SetScrollSizes(MM_TEXT,CSize(0,0));

I had an ActiveX control in my C++ project but deleted it. It still shows up in the Class Wizard control list though. How do I remove all references to a control from a project?
|

Kevin
exit Visual Studio, delete the projects *.clw file then start Visual Studio again. The Class Wizard file (*.clw) will be regenerated and all references to the ActiveX control should be gone.

Answer to your question is:

By the way, do you know how to change the MSysObjects attributes to read only thru VC?
I will be able to read tables info if I could do that. By default, MSysObjects cannot be read. I can change the setting thru Access 2000 but I want to do it thru VC!

I have noticed an anoying bug in my context menu. Here it is:
I have a SDI App, with the base view class of CTreeView. I have split the frame in two views - Left is Tree, right is the ListView.
When i insert the following code in to the OnContextMenu function
CMenu menu;
menu.LoadMenu(IDR_MAIN);
CMenu pContext = menu.GetSubMenu(0);
pContext->TrackPopupMenu(this->m_hWnd, TPM_LEFTBUTTON|TPM_LEFTALIGN|TPM_RIGHTBUTTON,
point.x, point.y, AfxGetMainWnd());
(I'm not sure if the parameters are in the same order - if they are not - ignore it, in the code they are correct)
The first time I right click it shows the popup menu which contains 2 functions, and also adds some elements from the help menu?! The second time i rclick it shows it as it should be. But if I display the context menu associated with the caption (Restore/Minimize/Close etc.) it makes the same stupid mistake.
What am I doing wrong?!
Any help appreciated,
Deian
