I have many HDIB hDib,
and want to see when variable with such a name chages,
with no relate to place in programm -
I do not know where to place breakpoint.
Memory leak happens,
due to some library - frees incorrectly HDIB,
which is alloctes flexibly by new [length] -
to solve this problem.
thanks

I have one dll file without any information about that file. I want to know all functions in that dll file. How can I do to list all functions?
|
|
|
|
|
dumpbin /export your.dll
lists all exports by that dll.
dumpbin is included in VC++ compiler packages.

You can also use the Depends (depends.exe) tool that comes with Visual Studio.

hi,
i have a dialog app. when i hit the start button i want to perform some steps and indicate each step with a little picture (one for failed, one for pass).
what should i use for this?
icons are always drawn big. i only need them to be 8x8. but if i use bitmap the background is not transparent.
how do i get what i want? or should i use something totally different?
code examples would be cool.
greets.

You can use a 16x16 Icon, draw your 'indicators' in the middle and leave a 4 pixel transparent border on each side.
For this you simply darw your icons, load them and draw.
If you get a stretched version of your icon (I aksed this question yestarday  Use LoadImage to indicate the desired size for your icon.
You can also use a bitmap with a mask-bitmap to mask out the transparent color, but I think Icons would be the easiest way for you.

I want to create a new document/view making its frame hidden till some lengthy operation is done and then show its frame, so I passed a FALSE value to CDocTemplate::OpenDocumentFile ‘s second parameter BOOL bMakeVisible in void CMainFrame::OnFileNew() message handler:
CMyDoc* pDoc = (CMyDoc*)theApp.m_pCPDocTemplate->OpenDocumentFile(NULL, FALSE);
How do I have to make this document’s frame and view visible again?
Thanks

Hello guys!
Does anybody know of some good CDROM burning libraries that I could use for a project of mine?
I want to add some CDROM burning capabilities to my programs...
Thank you in advance!

Hi!
The Nero api is pretty good but I recommand using something more general... Nero SDK only works if there is a nero burning program installed on a computer and everyone doesnt use nero...(but it is easier to use)
You can use the imapi.h header file which you can get by downloading the latest Platform SDK ( it includes cd-writing ) ... ( your program will work on computers with windows XP or with some other windows edition with a service pack )
Well... I am a beginner ...

Hi All,
We need to debug DB2-C Stored procedures sitting on Z/Os
(IBM). Those are embedded SQL C programs. We are using
Db2 Connect 7.2 to connect to the database. Now I want to
debug those C programs in VC++ editor.
If somebody has solution pl write to me.
Rgds

You'll probably need to set up remote debugging[^] with Visual C++ on the server.
You'll need to attach the debugger to the process that will run the C code - this is probably the DB2 executable, although I don't know which one this is - I'm not familiar with DB2.

Hi All
im getting this error when i execute the following piece of code
Run-Time Check Failure #2 - Stack around the variable name 'pbuff' was corrupted.
does ne1 know whats wrong with my code, im pulling my hair out here 
thanks
si
CString vChr;
TCHAR pbuff[32];
CString Out;
int num=0;
int nOffset=0;
int nRead;
//read in the 1st 32 bytes
do
{
for (int f=0; f<=32; f++)
pbuff[f]=NULL;
sName="";
nOffset+=32;
nRead = SimMem.Read(pbuff,32);
int nLen=0;
int a = (int)pbuff[11]+128;
TCHAR ch = (char)a;
for (f=0; f<10; f++){

}
}

You are running a loop from 0 to 32. Thats 33 times, but you only alocated space for 32 chars.
You need to alocate enough space (and dont forget the trailing zero for a string!).
Hope this helps
Who is 'General Failure'? And why is he reading my harddisk?!?

You missed the <= 32 so it stops at 31, although it would be better writte as < 32

Get into the habit of using sizeof() eg.
<br />
CString vChr;<br />
TCHAR pbuff[32];<br />
CString Out;<br />
<br />
int num=0;<br />
int nOffset=0;<br />
int nRead;<br />
<br />
do<br />
{<br />
for (int f=0; f<sizeof(pbuff); f++)<br />
pbuff[f]=NULL;<br />
<br />
sName="";<br />
nOffset+=sizeof(pbuff); <br />
nRead = SimMem.Read(pbuff,sizeof(pbuff));<br />
<br />
int nLen=0;<br />
<br />
<br />
int a = (int)pbuff[11]+128;<br />
TCHAR ch = (char)a;<br />
<br />
for (f=0; f<10; f++){<br />
sName += pbuff[f];<br />
}<br />
It will stop you hitting annoying bugs like this...

hi,
i am facing strange problem with IDM_PRINT.
i am using the brochure machine sample of microsoft and my own custom print template.it is working fine with the IDM_PRINTPREVIEW and i am able to see the desired result.when i try to use IDM_PRINT to print it directly,it justs does nothing.neither it invokes the print dialog nor prints .if i pass the printtemplate path as null the print dilaog comes up and prints.this seems to be very strange .would you please suggest me how you dealt with this problem.
thanks a lot

I am seeing the same issue described above.
Did you ever come to a resolution / workaround ?
Thanks,

Hi All, I'm using malloc, realloc and free to maintain variable length memory blocks, which I intend to use for a container template class. What I would like to know is how to initialise parts of the block by calling the constructor of my object of type T? I use malloc if the block is null and realloc if it isn't so initialisation is quite important (otherwise realloc will get called on a duff address == crash  ). Trouble is I can't use calloc to initialise the block bytes to 0 cos it'll only initialise the container the first time round (realloc is used thereafter), and secondly I have objects of x bytes that have _vfptr's which should not be NULL. So is there anyway I can initialise a new object when I allocate enough space for it? I can't use placement new because I need the allocation to grow or shrink. Aside from creating an object on the stack and memcpying it, I was hoping to be able to allocate the space and then call the objects constructor using that allocated space for its containment, anybody got any ideas? Thanks all for reading this far.
Alan.

AFAIK malloc is a 'C' function.
The operator new in C++ also calls that constructor. If you go with the C++ way of doing things - if you're using templates you have to be using C++, you can allocate a contiguous block of memory, then use placement new to construct the objects. Thats how the STL allocators work.
Don't forget mixing new and malloc is just asking for trouble...
If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts you aim;
Yours is the Earth and everything that's in it.

I would have a think about what you are trying to do, and see if there's an easier way of doing it. I know that may sound obvious, but using malloc and realloc to maintain a dynamic chunk of memory and then mapping C++ objects into it is going to be difficult (if possible), and asking for trouble. Realloc is not always some wonder-function that avoids memory copying, and often will just allocate a bigger chunk of memory and do the copying for you - it's very much a 'C' way of thinking.
You may be better off looking at something like the STL's vector (or list or whatever is most appropriate), and seeing if you can make use of its automatic ability to dynamically extend memory. It'll be a lot easier and save you many headaches. Object pools may also be something to think about, with you overriding the new and delete operators.

I am basically trying to create my own vector template container class, not so much for reinventing the wheel purposes, but to learn deeper memory management techniques. I know that new/delete calls the ctor for the objects it creates, but I am needing to dynamically grow/shrink the memory block. Realloc is nice in that it tries to extend the memory (or move the contents into a new block so it can extend it), I don't have to worry about copying the contents over every time the array grows one notch. Is placement new still a viable solution?

Hi
i search for a function which can do this:
double value = 4,6793
value = round(value,2) //after that value should be 4,68
in which library can i find this function???
|
|
|
|
|
do you mean round to 4,6800? or truncate to 467.93 and round to 468? I don't really get how you can get 4,68? You'll need to make you own round routine though if you want to do anything really weird with numbers
|
|
|
|
|
Hi i mean this:
round(y,x) y = value to round for example 4,6793233
x = position after ',' to round
round should look after y at position x+1
if y at positon x is > 5 then 4,68 forget the rest of
numbers!
