Hi,
How can i change the caption of the columns headers using the MS DataGrid 6 ?
Is there any way to find out which record is selected using the mouse click event ?
Best Regards,

There is one thing I can't figure out with VC 6.0 & ADO. How can I change the 'Background Fetch Size' (DBPROP_ASYNCFETCHSIZE) property of the recordset running asynchron? It's the number of records retrieved between two fetchprogress events. It's default is 15.
It's easy to do it in VB, but in VC++ before opening the recordset, I don't have any dynamic properties available, after executing the SQL the property is read only. I suppose if it's possible in VB it must be possible in VC++ 6.00 as well. I've hard times finding any docs about it even in SDK. As far as I know this OLEDB property is supported by the Cursor Service, which is initilaized when changing cursor to adUseClient.
Any idea?

I have a class on a library on the file Libr.h/.cpp
I build a doc/view app.
I link the header in Doc.h using #include "Libr.h",
and the code is pasted in Doc.cpp using #include "Libr.cpp".
View knows that the library exist because in View.h I have #include "Doc.h".
So I have some code that use the library in Doc.pp and View.cpp.
But the problem is:
Doc.cpp OK
View.cpp: Link error LNK2019 (functions not finded when link: but no problems when compile)
So I tried to past #include "Libr.cpp" in View.cpp, and then:
Doc.cpp: Link error LNK2019
View.cpp OK
Damn!
And this appens only with some functions of the library, and strange thing is that this functions are very very similar to other functions that haven't got any problem!!
Can anybody help me??
(sorry for the long message)
Have a nice code day

#include "Libr.cpp" is wrong.
Include Libr.h in your Doc.h & include Doc.h in your Doc.cpp

is actually not wrong but poor way of programming.

you need to add the lib file to the link tab in the project settings.

Hi,
I had the same link error.
I feel the problem is inclusion of your header files(#include "Libr.h") in side the Doc.h.
Try to include the header files inside the .cpp files, not inside the .h files.
If you want exactly inside the .h file, then include inside of #define.
otherwise system will produce runtime error because of multiple inclution.
in your case you included "#include "Libr.h" inside your doc.h and doc.h is included inside view.h and etc.. try to avoid this and "#include "Libr.h" should be inside your doc.cpp
Dont include .cpp file. .h file will take care everythings of .cpp
best of luck,,

Sorry, but I prefere the simple use of #include.
I have good news:
In libr.h/.cpp there was a lot of inline functions,
well... I modify the files cutting that word and now everything is running.
But I want to use inline: I need it!!
So, do you know if it is possible that the linker doesn't like the keyword inline or if the use of 'inline' could give this error??

linking the library to your project is also a simple way of doing.

btw, is the doc-view app a MFC project?

Yes

Add the .cpp file to the project and #include the .h file whereever you need.
It should compile and link properly.

Iam a beginer in testing and i need help in writing unit test cases. I have a Software specification document, use cases , my problem is how can i write unit test cases?

what software do you write your tests with ?
to get started, you have to consider for each part tested (in general, functions one by one) the purpose of it. then you initializes the context of which the function is called, the you know exactly what it is supposed to do, so, what would be either the result and the context left.
you must test this...
TOXCCT >>> GEII power
[toxcct][VisualCalc 2.20][VisualCalc 3.0]

Before start writing the test cases, you should know your software well. You should proficient and Should have step by step knowledge of your project. what are the previous step, next step, input and output etc.
try to go through some existing test cases of your project. I think this will helps you..
best of luck.

I would like to do a Dependency/sequential build on the files in .NET.
For example, I have 2 files x.c and y.c.
Compiling and Linking of x.c needs y.z( the output of y.c).
But since .NET builds in alphabetical order, I cannot aceheve this.
I have seen similar behaviour in VC++ 6.0 as well.
Is there a way to do this?

I use MSVC6 - Select "Project->Dependencies...". I'm sure VS.NET has a similar option.

I have a dialog with about 5 CEdit fields,
CEdit1, CEdit2,..... CEdit5.
Currently, when I clicked the TAB key,
the cursor will jump from CEdit1 to
CEdit3 instead of CEdit2.
Can someone tell how to fix it?
Thanks,
Kevin

open dialog in resouce editor for which you want to change tab order. Then in the menu you will see format, there is taborder option in it, click it and you will be able to change tab order by clicking controls in the order we you them to be selected when pressing tab.

I've seen in many source codes, some statements written in #if 0 block something like:
#if 0
printf("Blah Blah");
#endif
Please tell me what is the meaning of #if 0 in the code above.

it simply means the code in side the block is ignore for compilation and will not appear in the final build.
it is similar to saying
#if !defined(SOME_BUILD_FLAG) or<br />
#if FALSE<br />
<br />
#endif
since the dev wanted the code to be explicitly removed from compilation he used
#if 0<br />
#endif
directive

Then what is the purpose of the code inside that block ?
For example, if the code is written in #ifdef DEBUG block, it is skipped in the release builds but its purpose is clear and that is: it will be compiled in debug builds. So what is the purpose of writing code in #if 0 when i'll never be present in the executable.
