The struct won't solve your problem, it merely makes your design better. Add an iostream inserter/extracter and things would be really nice.

I know in c++ you could use setpercision to change the number of decimal places outputted. So how do you do it with the Cstring variable output in a dialogbox in mfc?
I have the following:
float Float_Percentage=0;
float_percentage = m_wins/m_plays;
CString PercentageConversion;
PercentageConversion.Format("%f",Float_Percentage); // convert float to str
percentvalue=PercentageConversion; // percent is of type CString
I get output like this 0.050000
How do i make it 0.05 as in just show two decimal places in a setpercision(2)?
Thanks for your help.

Use "%.2f" instead of "%f" to format the value.

I have a SDI and I dont override the standard file open ( i.e CWinApp::OnFileOpen() ), I do however use a separate CFileDialog to open a particular type of file.
When I use the CFileDialog to open my files I set the initial directory to open from (different from the executable dir). Then when I use File->Open it uses the CWinApp::OnFileOpen and the initial directory is the last directory from my CFileDialog, I expect this.
However I used SetCurrentDirectory to reset this directory but it still uses the previous value. It also uses this value when I retart the program and choose file->open.
How can I set this to always open in the executable directory for file->open. I dont want to override the OnFileOpen and use a CFileDialog.

Here's my code
int ParsePacket(BYTE *aPacket,short int iStartPos);<br />
<br />
<br />
void main()<br />
{<br />
BYTE aPacket[] = {0x59,0x89,0x59,0x59,0x23,0x59,0x59,0x59,0x89,0x59,0x00,0x54,0x65};<br />
int l = ParsePacket(aPacket,5);<br />
printf("%d\n",l<br />
system("pause");<br />
}<br />
<br />
<br />
<br />
int ParsePacket(BYTE *aPacket,short int iStartPos)<br />
{<br />
bool bFound = false;<br />
int iPos = 0;<br />
<br />
for (int i = 0;i < (sizeof(aPacket) - 1); i++)<br />
{<br />
printf("Test: %x\n",aPacket[i]);<br />
}<br />
<br />
return iPos;<br />
}
This piece of code should output twelve values ( sizeof(aPacket) = 13 ), but instead it only outputs the first three bytes of aPacket... why?
|
|

|

TO get a hint as to the problem, you should have added an printf for "sizeof(aPacket)". In the context of the ParsePacket function, sizeof(aPacket) is 4, because ParsePacket recieves aPacket as a BYTE *, and on the 32-bit x86 architecture, all pointers are 4 bytes. The sizeof operator has no way of determining the length of an array pointed to by aPacket.
i.e.:
//-----
#include <windows.h>
#include <stdio.h>
int ParsePacket(BYTE *aPacket,short int iStartPos);
void main()
{
BYTE aPacket[] = {0x59,0x89,0x59,0x59,0x23,0x59,0x59,0x59,0x89,0x59,0x00,0x54,0x65};
printf("size (in main): %i\n",sizeof(aPacket));
int l = ParsePacket(aPacket,5);
printf("%d\n",l);
system("pause");
}
int ParsePacket(BYTE * aPacket,short int iStartPos)
{
bool bFound = false;
int iPos = 0;
printf("size (in ParsePacket): %i\n",sizeof(aPacket));
for (int i = 0;i < (sizeof(aPacket) - 1); i++)
{
printf("Test: %x\n",aPacket[i]);
}
return iPos;
}
//-----
outputs:
-----
size (in main): 13
size (in ParsePacket): 4
Test: 59
Test: 89
Test: 59
0
Press any key to continue . . .
-----
You need to pass the length of the array to the ParsePacket method.
i.e.:
//-----
#include <windows.h>
#include <stdio.h>
void ParsePacket(BYTE *aPacket,int aPacketLength);
void main()
{
BYTE aPacket[] = {0x59,0x89,0x59,0x59,0x23,0x59,0x59,0x59,0x89,0x59,0x00,0x54,0x65};
ParsePacket(aPacket,sizeof(aPacket));
system("pause");
}
void ParsePacket(BYTE * aPacket,int aPacketLength)
{
for (int i = 0; i < aPacketLength; i++)
{
printf("Test: %x\n",aPacket[i]);
}
}
//-----
outputs:
-----
Test: 59
Test: 89
Test: 59
Test: 59
Test: 23
Test: 59
Test: 59
Test: 59
Test: 89
Test: 59
Test: 0
Test: 54
Test: 65
Press any key to continue . . .

Hi!
The Hebrew version of my software works fine on Win XP English and Hebrew but it will display gibberish on Win98 Enabled and Hebrew. It will even mess up the fonts for the complete OS.
I havent seen the problems myself, I have someone over in Israel that is testing for me.
Is there anything to take care about for Win98 Enabled and Hebrew?
Thanks!

This is my dilema. I have somethings I'd like to accomplish. The first thing is to get stars(*) to appear when someone puts in thier pin(it's an ATM program). I haven't quite figured it out and I need help understanding it. The next thing would be help with sub-classing. I read a couple of articles on it. NCP(Number, Currency, Percentage) edit controls. The other article I read was on sub-classing. I have an understanding(I don't know for 100% though) of sub-classing for buttons. I've tried doing the same thing for edit controls but I'm having problems understanding it. I'm using Dialog Boxes. Thanx to those to have helped me before and thanx to those who wrote those articles they helped. Thanx for your time and help.
Sincerely

As for your password problem. If you go to your dialogbox and the edit box you just made. Do the following.
Right click on the edit box and go to properties. Then go to style. Put a check mark in password and then whenever you type anything in the edit box you will get ***'s. Hope this helps.

I'm looking for an interactive 2d graph control, but the ones in the miscellaneous controls category all seem to be static. By interactive, I mean having the ability to select and move the graphed points with the mouse.
Any ideas?

I'm hosting MSHTML in an Explorer bar, and a specific Web page is causing a crash in MSHTML. No other page has done that for me. I'm trying to figure out why it's happening, but I can't make sense of the call stack. MSHTML is hosted with a download control which should be preventing dynamic content from being displayed/executed, so it's curious why the call stack appears to be attempting to process some window message. Or maybe not. Any pointers? Thanks!
Here's the call stack I obtained from VS.NET:

Hi, i´m having some problems to install a lsp on a Windows NT 4 Service Pack 6.
It´s Fail at WSCInstallProvider(...)
The Strange Thing is that LSP is working fine on Windows 2000, and Windows XP.
I Didn´t find any changes (prototype or argument numbers) related with this function.
Somebody here knows what could be happening ?
Thanks,
Victor

I have a system tray icon that displays a menu when you right click on it, but it doesn't disappear when you click elsewhere on the screen.
To make it disappear you have to click an item on the menu.
Does anyone know why this is happening?
Thanks

What happens if you specify TPM_LEFTALIGN as the first parameter?

It doesn't seem to do anything, and even if it does it doesn't help.
Any other ideas?

I had exactly the same problem a while ago. Search the microsoft knowledge base for Q135788 to get
the explanation.
...Create menu hMenu...
SetForegroundWindow(hWnd);
BOOL nReturn = TrackPopupMenu (hMenu, TPM_NONOTIFY | TPM_RETURNCMD | TPM_LEFTBUTTON, pt.x, pt.y, 0, hWnd, NULL);
PostMessage(hWnd, WM_NULL, 0, 0);
