hi all,
i'm using ADO and datagrid in my project, which is working fine in my machine. But when i made a setup and ran in another machine it was not working , there is problem in loading the ADO or data Grid. DSN name is coming correctly since i included the code for that when i made set. i also included the all the MFC dll(like MFC42.dll,etc) which i used to include.
Should i include any other dlls or any registry entry when i use these(ADO n data Grid ) when i make setup?
kindly reply,
thanks in advance...

Use the vc tool "Depends" you already have to find all the dlls your progam depends on.

The data is in a table in SQL Server 2000, like this
Time Price
2007-01-01 10.00
2007-01-02 11.00
I need to draw something like MA5,MA10,MA20,MA50 in stock software.
My method is:
1. Get current value
2. recordset->Move(-n,adBookmarkCurrent) //some times, n>1
3. Get summary, cycle
4. Get average value
I find it is very slow when drawing.
Who can give me any suggestion?
Thanks.

Which means what? Are you having trouble compiling? Are you receiving a run-time error (assertion, exception)?
Assuming the device is sending data, it shouldn't take more than a few lines of code to test the connection. After that, you can start fine-tuning stuff.

I am building a dynamic data table type that can have its metadata defined at runtime,
so the Table class will have a vector containing charater arrays of unknown length when
the class is defined.
I need to make a decision about how to handle memory allocation/deallocation for the Table
class. In the trivial example below, how and when is the memory that is allocated by new, deleted?
If I clear() or erase() elements from the vector, will it also be the same as delete []'ing the contents of the vector (the arrays)?
#include <iostream>
#include <vector>
#include <string.h>
void Add_record(std::vector<char*> &Table){
char *n = new char[80];
strcpy(n, "Hello World!");
Table.push_back(n);
}
int main (void){
using namespace std;
vector<char*> Table;
for (int i = 0; i<10; ++i)
Add_record(Table);
for (int i = 0; i<10; ++i)
cout << "Table.at("<<i<<") = "<<Table.at(i)<<endl;
std::cin.get();
return 0;
}

Depends. Most modern operating systems will reclaim the memory when the process exits.
|
|
|
|
|
I may need to reuse the memory in this Table or possibly another one.
That is, while the process is running.

somehow I missed that question from your first post... oops.
No it does not free the memory allocated when you used the new operator

I don't know what you mean by "reuse the memory". As long as you have the pointers in the vector you will have access to them. If you clear the vector, based on the code you posted, you will no longer have access to the memory.

Don't bother #includeing string.h and using char*: instead use #include <string> and
std::vector<std::string> and forget about memory allocation issues.

Is there any simple way how to change frame around the Edit box

Or how to subclass Edit?

I can not access border in this message.
It draw rectangle around white part, but border are still there.
And when I turn off border in resource editor, my rect is partly covered by text background.
All Edit SubClass codeproject items, I had found, are about behaviour of Edit none of them about painting.

search codeproject with keyword "SubClass" you will get many article, which will fulfill your need

Hi
I'm new to Visual C++ and .NET Framework; I'm trying to display a bitmap image on a Windows Form in Visual Studio 2005 but am experiencing problems with this.
I have examples for VS 2003 but these don’t seem to work in VS 2005.
Does anyone have any examples of displaying a bitmap in VS 2005?
Any help appreciated

You asked on the C++ forum so on the c++ you can use of LoadImage for load image and use of WM_ERASEBKGND for show this image.;)
|
|
|
|
|
but he specified to use WinForms, so we can decently understand that he is on the wrong place... 
|
|
|
|
|
Yeah I saw his question but I said to him you asked on the c++ forum its meaning if someone answer to him answer will be c++ or c++.net,right!?;)
