Hello Mr Haes,
If your database reside on Internet/Intranet Based Server you have to make Three Tier application.
i.e.
Your VC Application ---> Through POST/GET method post data to server <--> Middle Layer Validate it <---> Store in database!

This article demonstrate Data POST/GET:-

For Storing the data in database, Please refer manual of Web language you are using.

CButton Sib-class

I need to start a timer when a button is pressed and then stop the timer when the button is released.

I think I need to sub-class CButton as dont have the WM_KEYUP or WM_KEYDOWN events in the CButton class.

Can someone point me in the direction of how to sub-class a control in Visual Studio 7.1 please.

Many thanks,

Graham.

write the start timer code and Stop Timer code on the BN_CLICKED event of the button. Change the caption of the button to "STOP TIMER" when the timer starts.
Check the caption of the button before branching to the appropriate code.

Help with ASCII conversion

rexpiper13-May-05 9:07

13-May-05 9:07

I have a date time stamp which I have read from a file. I have read it as ascii characters and have stored it in a character array as follows:

The data is stored in the reverse order in the file where I read it i.e. [0] [1] [2] [3] [4] [5] [6] [7] has to be reordered as [7] [6] [5] [4] [2] [1] [0]. The bytes are put into a character array as a hexadecimal representation of a timestamp.

(actual example)

dt = "0x01c5556a92792c8c0"

Now in order to pass it to the localtime function I need to convert this ascii hex representation of my timestamp to an int64. I must be having a senior moment but I can't figure out how to do this (seemingly simple) operation.

Could someone more experienced please help me with this?

Thanks

Maybe not the shortest way, but should work:

__int64 test;
char buf[128];
const char dt[] = "0x01c5556a92792c8c";

memset(buf, 0, sizeof(buf));

for(int i=0;i<8;i++)
{
	int n = strlen(dt) - ((i+1)*2);
	sprintf(&buf[i*2], "%c%c", dt[n], dt[n+1]);
}

sscanf(buf, "%16I64x", &test);

What do i use to make a DOS app

Well i have this perfectly terible text type game that, for testing purposes i want to have a DOS version of. (At the moment its just a console app, not DOS compatible)

Here is a sample of the code, and yes its pretty much all like this:

********************************************************************
//The text based carrot game brought to you by me

#include
using namespace std;

int main()
{
char a [50];
char b [50];
char c [50];
char d [50];
char e [50];
char f [50];
char g [50];
char h [50];
char i [50];
char j [50];
char k [50];

cout <<"This game was written by -. HELLO and welcom to the CARROT ADVENTURE TRILOGY wich contains all 3 carrot advantures. Enjoy.";
cout <<"\n\nYou are a carrot with no family and no friends and are rather quite lonely, have a look for an inanimate abject to be your new friend, what can you see?\n";
cin.getline (a,50);
cout <<"\n\nCONGRATULATIONS you have found the ";
cout <

AFAIK, if you restrict yourself to the C++ Runtime functions, your code should run (after compiling it with a 16 bit compiler, of course).

I'm not sure exactly what it is that you are asking. A console application is one that runs from a command prompt. By the use of cout and cin in your code snippet, it certainly qualifies.

you can use any of the VisualC++ versions, with C or C++, any of the C-runtime stuff, any of the C++ runtime stuff, including the STL, MFC, etc.. you can use C#, if you want, too. there aren't many limitations.

I thought the OP wanted to write a true DOS app, i.e, one that runs on a system running on just DOS and no Windows.

@Printer Driver....

Hi,

I want to develop a printer driver which will be installed in the Printers folder and will print the document to a JPEG file. Irrespective of the application firing the print job, if this driver is selected, then the output should go as a JPEG image.

Eventhough I have more than 4yrs expirience in VC++, I am very much new to this space of driver development. So I would like to get some starter documents or some sample codes. If anyone of you have come across similar things in the past, kindly send me the details.

Thanks and Warm Regards

CListCtrl CustomDraw/OnCtlColor Quandary

GregH13-May-05 6:02

GregH

13-May-05 6:02

I have a CListCtrl derived control on a dialog using the report style. The dialog has a BMP as a background. Using SetBkColor and SetTextBkColor I have made the CListCtrl transparent, allowing the BMP background to show through. This works correctly, with one exception, the first column. This first column is not drawn transparently, but is instead drawn with a black background. All other columns are drawn transparently.

I have attempted to force this cell to be drawn transparently by handling the NV_CUSTOMDRAW and WM_CTLCOLOR messages, but have so far been unsuccessful. Am I on the right track here, or am I missing something obvious?

The term "best" is very subjective. What's best for you might not be for someone else, and vice-versa.

Debugging IE Addon from VS.NET

Hi,

If I am writing a toolbar application for IE using VS.NET, how do I debug my application?

If I set the Project properties' Start Application value to C:\Program Files\Internet Explorer\iexplore.exe, it is a release version and hence I can't debug.

How can I launch IE from my project and still debug my code?

-Thanks in advance

Didn't try it on a IE addon.
But why dont you try to hard code a breakpoint in your code, that will launch the debugger automatically?

add this line to the function of your choice in your add in
__asm int 3

No, VS is saying that the app you picked (IE in this case) isn't a debug version. You can still debug your code however.
