isn't this a bit overkill ? or maybe I'm mis-understand you point,
Me think it's easier to just swap items in the "data source" and refresh the list (if in "virtual mode" than it should not be any problem performance wise.

You can delete and refill the whole content or the changed items.
Or: they should originally be sorted and than change the index. This leads to costum sort

Maybe you mean drag and drop? Click an item, drag to a new position, and drop?
If that's the case, there are several articles about it on CodeProject, as well as a mountain of examples and tutorials elsewhere on the net.
There are three kinds of people in the world - those who can count and those who can't...

To move an item up:
Call GetNextItem(-1, LVNI_SELECTED) to get the item's index.
Call GetItemText() to get the item's text.
Call InsertItem(nIndex - 1, text) to insert the item in the previous position.
Call DeleteItem(nIndex + 1) to delete the old item
You'll obviously need to massage this a bit to get it to work (e.g., make sure that you don't try and move item 0 up). Moving an item down is almost identical.

SQL statment is
"SELECT COUNT(*) FROM [User]"
[User] is a table name, which contains handreds of records.
then I use CRecordset.Open(...) to execute the statment.
but CRecordset.GetRecordCount() function returns 1 always.
I think it is not a good way to go throught all records by CRecordset.MoveNext() - it is too slow.
how to get number of records in the table by SQL directly?
1) is CRecordset right class to execute the SQL?
2) is the SQL statment correct?
thanks for any help.

That's obvious: your query asks for exactly 1 record, containing 1 field: the number of records.
The value you're searching maybe obtained using CRecordset::GetFieldValue method [^].

For that function to give you the result you want, you'd have to use the SQL query "SELECT * FROM User". But don't do that - let the database engine do the maths and return the result as a single-field, single-row recordset, and read the result from that value, as CPallini said.

Have you thought of using IMAPI[^]?
There's a CP article[^] that details how to add lists of files and directories to the image. It's in C#, but really, how difficult could it be to convert that article to C++? To be honest, the IMAPI stuff is probably easier from C++ than C# - the article uses interop to access IMAPI...

Hello everybody,
im creating a picture control in a dialog box (win 32), i need to show an image in that control, but my bitmap is of 30 X 30 size, but the control is 100 X 100, i would like to stretch the image upto 80 X 80, so that picture control is filled with the same image.
Thanks in advance,
A. Gopinath.

You may use my DLL [^], if you need to stretch it without loosing too much quality.

is this possible?
I launch a process from my main process and when the second process attempts to use DLLs that the first is using, the second program crashes. However, when I click the icon for the second application while the first application is running, it accesses these DLLs just fine. I have used CreateProcess and ShellExecute to launch and both provide the same outcome. If CreateProcessAsUser is the solution, will it work for creating the process as the same user who launched the first process?

The answer is yes for your question. 
But I geuss it is not the solution for your situation.
Is the platform vista? If is that so, some issues are around UAC...
Is it the fact the reason of crash that is origined from some of security context errors?
|
|
|
|

You should be able to give the new process a different security context by using lpProcessAttributes->lpSecurityDescriptor.

Consider the following code in C:
#include<stdio.h>
#include<conio.h>
void main()
{
int n;
clrscr();
scanf("%s",n);
printf("%s");
getch();
}
Question: The above program amazingly reads a string and prints it but I don't know how/ Plz help me.
Plz specify the working of scanf and printf in the above program. n is not given as an address to the scanf function and printf contain only format strings.
Awaiting a good reply

In the scanf call, scanf will take n to be a char* value, so will store the string read in at the address given by n. You're just 'lucky' that n's value is equivalent to a writeable address.
The printf call? Well, as printf is a variadic funtion, it'll look up the stack from the pushed format string, looking for argument values. The next value on the stack above the format string is (you guessed it!) n, so printf will see n, interpret it as a char* value and print the string at that address.

Hi,
I am working on MFC Asynchronoussocket program, I could able to successfully send and receive messages between one to one client and server using accept, receive classes. But when i am trying to connect multiple client to server, my application crashes. And I also wonder, if I able to accept multiple client, how would I match the send and receive messages between different clients and server.
Could anyone please help me out!!!
Thanks

I've only looked at the basics of this quite some time ago, but the structure that accept() populates on the server has a sin_addr member. Can you pass that to inet_ntoa()?

Thanks david, I solved it - now I could able to establish mulitple client with single server, but I am facing problem in receving messages from clients. Server couldnt receive the message that client is sending. On client side, client is sucessfully sending the message. Could you please throw some light.
Binding i will look into it later once server start receving messages

Hi.
I have a program which is creating a huge memory leak. Here is an example of my program. This is not an actual code but an example which references my program.
Class ABC
{
static int *B;
}
Class DEF{
int *MALLOC_C[20];
void Function1(int* ptr);
void Function2( );
}
ABC[10];
DEF[10];
void main()
{
int *sample=new sample();
*sample=1;
ABC* Object1[20];
DEF* Object2[20];
for(int i=0;i<20;i++) //Edited
{
Object1[i]=new ABC();
Object2[i]=new DEF();
}
for(int i=0;i<20;i++)
{
Object[i].Function1(sample);
}
for(int i=0;i<20;i++)
{
delete Object1[i];
delete Object2[i];
}
}
DEF::Function1(int *ptr)
{
ABC::B=ptr;
}
DEF::Function2()
{
for(int i=0;i<20;i++)
{MALLOC_C[i]=(int*) malloc(1000*sizeof(int) ); //Edited,Corrected
}
//DO processing on MALLOC_C
for(int i=0;i<20;i++)
free(MALLOC_c[i]);
}
This is what I am doing. What is wrong? Please help!

why is this line inside a for(i) loop and not using i?
