Hi everyone,
i am doing concatination in my activeX control project.means i am having two varibles one is MemId is of type LPCTSTR and another one is strmsg is of type char *strmsg.this is in read block function.
i am doing like this:
MemId=dStr;
strmsg=strcat(strmsg,MemId);
MessageBox(strmsg);
it is not giving error but when i execute my actual program in that i used this activeX control. that time is giving send error or dont send error message box.
afterwords i changed this to for first time i used string copy function but it is also giving same error.
Please Help Me what's wrong with my code.
**********THANKS IN ADVANCE*********

Have you allocated strmsg?
possibly you are not allocating char *strmsg; you need to allocate memory for the string. something like char strmsg[YOUR_STRING_SIZE]; char *strmsg = new char[YOUR_STRING_SIZE];

It seems your module is not unicode as strcat doesnot give error at compilation taking (char *, LPCTSTR).
And as a side note, IMHO, when you are using generic string data type LPCTSTR always use generic text manipulation API's and data structure, use _tcscat inplace of strcat.
Unicode, MBCS and Generic text mappings[^]
generic text apis start with _tcsxxx search in msdn index when you want a mapping to string functions with strxxx

Thanks for your suggestion but still not working.

Try DRA::ImageList_AddIcon

#include <stdio.h>
#include <malloc.h>
int min(int a, int b, int c)
{
int temp=a<=b?a:b;
return temp<=c?temp:c;
}
int MinOperation(int len1, char str1[], int len2, char str2[])
{
int count[10001][10001];
int i,j;
for(i=0; i<1001; i++)
count[0][i]=0;
for(i=0; i<1001; i++)
count[i][0]=0;
for(i=1; i<=len1; i++)
for(j=1; j<=len2; j++)
{
if(str1[i]==str2[j])
count[i][j]=min( count[i-1][j-1], count[i-1][j]+1, count[i][j-1]+1);
else
count[i][j]=min( count[i-1][j-1]+1, count[i][j-1]+1, count[i-1][j]+1 );
}
return count[len1][len2];
}
void main()
{
int i=0;
int len1;
int len2;
char str1[1001];
char str2[1001];
scanf("%d%s", len1, (str1) );
scanf("%d%s", len2, (str2) );
puts(str1);
puts(str2);
printf("%d", MinOperation(len1 ,str1 ,len2 ,str2));
}
I am not sure why there exist a bug stack overflow?

if you specified parameters for scanf correctly, the above, then the stack overflow is due to the stack allocation int count[10001][10001]; which is "10001 * 10001 * sizeof (int)" which is very large than the default stack size which is 1MB. To increase the stack size /STACK (Stack Allocations)[^].
It is better to allocate in heap.
And also array size in main 1001 and size in MinOperation 10001 check it for logic of your program (Any way int count[1001][1001] is also going to issue stack overflow).

Hi all,
I am new to this group.I am developing an IDE for my project.
I want to know whether i can create dockable windows using MFC only.
I dont want to use WTL classes in my project.
I am working on Visual Studio 2005 environment.
Can any one help me with the source code for creating a dockable
windows with MFC only?

Hi,
I am trying to compile the custom created MFC Activex control for my Applciation, I am getting following Errors:
Plz help me how to overcome this..

You might want to check the LIB files you are linking to. One of the ways that this can happen is if you link to a static library which was in turn built statically linked to a CRT. So now, you've got 2 copies of the CRT that you are linking against - causing the multiple definition errors.
If the other library you are linking to is under your control (i.e. you have the source and can build it), then see if you can get it to link dynamically to the CRT as well. If it isn't, well, then its a bit tricky. You might have to tinker with the /NODEFAULTLIB option and try to use the CRT that comes with the 3rd party LIB.

I use evc++ extensively, which is sufficiently close to VC 6.0 that I think I am safe asking this question. I have a relatively large project - 600+ files - and I've started having to rebuild all files when I change targets. For some reason the ide / nmake decides I've changed something very important. Any ideas as to tracking down what file is triggering this?

I also use EVC 3.0 and 4.0 with similar sized projects. Unfortunately what you're experiencing is normal as far as I can tell. When you change targets you're changing SDKs, derived from the different builds of CE with different BSPs. Any headers from the CE build used in your project, and there's almost bound to be some, will therefore change and if they're globalish headers everything will want rebuilding. You may be able to mitigate this a little by carefully trimming your #include inclusions but a full rebuild is still going to be needed in a lot of cases. Add to thi the known issues with the mostly failed attempt at an incremental linker that comes with EVC4/MSVC6 and you're probably better off wiht a full rebuild anyway. Good luck

I'm at 4.1 and 5.0. Although I understand what you are saying, the target files are split according to SDK/target, and this *was* working in the past. It's just recently the thing has become possessed and insistent on rebuilding every dang file. It tasks me.
I'll keep looking, I know I'm going to have to go into the command line and run nmake manually to see what is going on. If I learn anything useful, I'll post it back here.

If nmake doesn't cough up useful results take a look in EVC under Tools, Options in the Directories Tab and make sure the folders for each Platform are correct for each type of directory and the lists are in order of precedence. This information is not saved in the workspace, it's IDE config in EVC4 and MSVC6 and can seriously screw up your projects if it's wrong. I hope you can crack it.

What do you mean by "switch targets"?
As for the nmake aruments, -n and -m are the ones I think you want and pipe the output to a file. Another is -B to force a full build; a test I do is build with -B then without and if the second does anything I look further. Occassionaly we get problems with the system clock on different system and around when daylight savings time changes.

hard to explain w/o a screen shot. In vs, let's say you can build for release or debug. Well, in evc++, the ide targets platforms - say x86 and ARM (different processors). Under each platform, you can have a release and debug.
For example, in my case, I have two platforms and two targets for each platform - 4 possible executables.
I have to tear into the nmake and see what we've done to the dependencies to trigger this....

Doesn't nmake.exe have some sort of command-line switch that shows what files are out-of-date but doesn't actually build them?
