You basically want to download paintlib ( www.paintlib.de ) to read the tiff, then select the image into a DC and use MoveTo and LineTo to draw your lines.

Hi all,
Im trying to incorperate a chat sort of thing into my program. It has a list control on the side listing the people who are connected to the room, a edit box where people enter their text and a list box which displays the text that people enter.
Okay, now I want to be able to do all that stuff, cept I got no idea how.
If you think you can help, or have a sample application that does that, please respond to this message or email me at pajen007@bigfoot.com
Thanks

Your query,
Creates many questions,
There are many different means of creating a chat app,
1. IRC
2. Web Based
3. Messaging,
4. Peer to Peer !
All of them have benefits and problems,
I found Friendly Talk useful resource.
Many people don't like it as it contains proprietry information to tenebril !
But Hey I got it working in less than an hour !

Hi Wolfram!
A friend had a book once, I think titled "Advanced Multimedia Programming". I guess it has some demo apps w/source for that thing.
Unfortunately I don't recall the website of the author today! 
But let me search in my old papers maybe I come up with something! 
Cheers

Hi,
Have any of you ever succesfully used the build-in profiler in VC6?
I have tried on several machines without luck.
After my App have finished, VC tell's me that it can't find a file in the outputdir called "test.pbo" (if my project is called test)...
Any ideas?
TIA,
- Anders

Heres a hard coded sample of assigning "Hello" to this variant bstr value. How would I assign a char* or char[] to bstr?
char *cTemp="Hello";
char cTemp2[32]="Hello";
VARIANT v;
v.vt = VT_BSTR;
v.bstrVal = SysAllocString(OLESTR("Hello"));//work ok
// how would I assign these?
v.bstrVal = cTemp;
v.bstrVal = cTemp2;
|
|
|
|
|
There might be smarter/better ways to do it, but the following code works
char *t = "just testing";
CComBSTR bs;
bs.Append(t);
VARIANT v;
v.vt = VT_BSTR;
v.bstrVal = bs;

You don't assign a char* to a BSTR, because a BSTR is not a C string. If you want to create a BSTR from a char array, use an ANSI<->Unicode conversion function, for example T2OLE:
#include <atlconv.h><br />
<br />
V.bstrVal = SysAllocString ( T2COLE(cTemp) );

Thanks I found the follwoing seems to work...
var.bstrVal = (_bstr_t)cTemp;
|
|
|
|
|
No, that code is incorrect. It will not work reliably. You're putting into var.bstrVal the contents of a temporary variable, which gets destructed once that assignment statement completes.

I am trying to update a .dbf database. I opened the database and the
CRecordset derived object with settings so the database could be
updated. CanUpdate() returns true. Yet when I try to call Update(),
I get a message that says the database is read only! How can this
happen, and how do I fix it?

Hi!
I'm trying to write a DLL, which contains calls to COM methods.
Most calls works OK, and everything seemed fine in the beginning,
but now I've encountered that a COM method call genererates an
access error (STATUS_ACCESS_ERROR).
What I'm actually trying to do, is to use the Microsoft Platform
SDK with Borland C++, which is seemingly hopeless. Therefore, I'm
wrapping my methods up in a DLL written in Visual C++ with the
wanted PSDK calls (actually the WIA SDK for Windows ME), and then
using this DLL in the Borland program I'm creating.
I haven't really encountered any access errors writing DLLs before,
so I thought everything was going to be fine. But I suspect that
some sort of initialization should be done in the DllMain-function
related to memory handling?
By the way, if I try the same COM-call in a "real" application,
everything works fine, only the call in a DLL makes the access
error.
I would be extremely grateful for any help or suggestions when
it comes to what could be wrong. I could include code samples,
but don't think they are needed. Some general guidelines to DLLs
could be enough to get me on track!
Regards,
Lars Ove Claesson

Anyone looked at Microsoft Money and said, "I know exactly how they did this. "?
I have a contact manager project ahead of me, Feb/Mar... and was thinking of the look/functionality of MS Money. There are a lot of things that seem different from the normal Doc/View architecture. Any thoughts?
Thanks!
Scott!
PS. Please don't flame if this is a stupid question, I am new to non wizard generated gui plumbing, but am willing to read and practice to gain necessary knowledge.

Can you post a screenshot , I've never seen it !

However I remember reading circa Internet Explore Release 4.7, that the GUI of MSMoney had been changed to a MSHTML driven App using the IE components,
But Like I said I've never seen MSMOney !

How do I get current projects name and path using Visual Studio macros?

To get the 'active' projects' name try..
Application.ActiveProject.Name
To get the full name (I assume the path is in here..)
Application.ActiveProject.FullName
