Dear MFC Gurus!
My brains don't want to work. I have no ideas. I'm writting simple MFC-based application. ShellExecute doesn't
work in my application (in other words, when clicking the static control, MSIE doesn't start):
UINT err=(UINT)::ShellExecute(NULL,_T("open"),_T(WEBSITE),_T(""),_T("c:\\"), SW_SHOWNORMAL);
This returns "SE_ERR_ACCESSDENIED". Why?
By the way, I have another project in the _same_ workspace where it works fine. Moreover, I used this scheme
always but today it doesn't work! Help! Urgent!
Yours sincerely,
Alex Bash

What is the value of WEBSITE at the time of this call? There is nothing wrong with the code as it works for me.

Sorry,
#define WEBSITE "http://www.microsoft.com"
The problem is still not resolved. I'm in shock. Any ideas?
Yours sincerely,

Hi,
I'm currently do some work involving images which have been stored in RAW format. Although I can perform all the necessary computing on them one 'nice' thing that has been requested is that my program displays the initial image so that different points (areas of interest) can be selected on the image instead of the co-ordinates being read in from a file. Does anyone know how to display this type of image using VS C++ 6.0 and MFC?
Also (I think I may have solved this one already, however....) how can the window be resized to a fixed size?, e.g. 320x240. The program is SDI and derived from CView.
many thanks,
Andy

It depends on what you mean by RAW format?
If you have direct access to the image bits then you can create a bitmap (or DIB Section) the same size as the image and write a function to translate (copy) from one format to the other.

Answer: over-ride the OnSize() handler.

I keep getting a linker Error 2005 about functions already being defined for every class I try and make in VS.net. I program my classes by putting the class definition in one file and them the actual code for the functions in a seperate file. for example:
***myclass.h file***
class myclass
{
public:
void myfunc();
.....
***myclass.cpp***
#include "myclass.h"
void myclass::myfunc()
{
.......
This will always give me a linker error that there are two definitions for the function myfunc in the object file. I can make the error become a warning if I use the linker command /FORCE:MULTIPLE but that does not seem like the best way to overcome the problem even though the program will work fine when I do that. Does anyone have some helpfull suggestions to solving this problem. (I do not want to put the meat of the function in the class definition as sometimes the functions are rather big.)

I doubt that in myclass.h, the function is declared as void myfunc(){ }; // with brackets. this is considered as a definition. Maybe.

Im not exactly sure what you are trying to say with this are. I am not useing {} with the function in the class definition and that has been the stand that worked with every borland compiler I used in the past. I just recently started using Visual Studio.NET(2002) and now the convension gives me errors. I have even gotten errors trying to compile sample cade that was included with the Visual Studio Software. I wish I had the computer in front of me with compiler on it to try things out. but i have to wait till I get home to try anything.

These are the same thing. Typically, the declaration of a class typically goes in the .h file, and the definition of a class goes in the .cpp file.
Anyway, at the top of the .h file, do you have something like:
#if !defined(AFX_MYCLASS_H__83972473_D4D1_4923_9BD8_0FD75D2FB39C__INCLUDED_)
#define AFX_MYCLASS_H__83972473_D4D1_4923_9BD8_0FD75D2FB39C__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
class myclass
{
}

Can any one of tell me how to get ip address from mac address . i know i can get it by using rarp command but i want to get it by using my program... Thanks in Advance
|
|
|
|

That I know of, the IP address is tied to the NIC, but not vice versa. Correct? If so, then you'll need to call gethostname() followed by gethostbyname().

Hello David thanks for ur response but i think those functions wil not work with mac address i suppose ..
they r working only for hostname or ipaddress..
if i am wrong tell me the way for getting ip address from given mac address
|
|
|
|
|
In addition to kuphryn's suggestion, the MAC and IP addresses can also be obtained from GetAdaptersInfo(). I've an example of this if you would like me to send it to you.

One solution is GetIpNetTable().

Hello Kuphryn !! thanks for ur hint.... but by using the GetIpNetTable() function we r able to get the ip address present in our host computer arp entry but i want a function like gethostbyname() which gives ip address of specified system name present in the LAN, bcos in my application i am capturing the mac address i don't know how to get the ip address from that .. the arp entry contain a very few entries only .. if u find any solution please do reply

it compiles, runs, but makes nothing transparent. my code runs well on WinXP and Win 2000.
in the MSDN is written, that it should also work with win98!
does anybody has a clue? or an implementation of a alphablend funtion?
the code i use is:
//blalba
BLENDFUNCTION blend;
blend.BlendOp = AC_SRC_OVER;
blend.AlphaFormat = 0;
blend.SourceConstantAlpha = 110;//(wichtigster parameter (zw. 0 - 255))
blend.BlendFlags = 0;
AlphaBlend(dcMemBackground, 0, 0, nWidth, nHeight, dcMemForeground, 0, 0, nWidth, nHeight, blend);
thanx, greets

I am having a difficult time trying to get a value to increment. What I mean is if I have a static control for example called CValue that each time a button is pressed it will increase the value by one. So if CValue = 10 and the button is pressed, I want it to change the value of CValue to 11. Each time I try to do this, the compiler says some crap about converting CString to an int is impossible or something. I cannot remember because I just got out of bed to write this so that I may have a reply by the morning.
Can someone please help me. I know this is easy 'i think' but it has me tickled pink.
Thankyou
Ashman

Have you tried something like:
CString strValue;
CValue.GetWindowText(strValue);
int nValue = atoi(strValue) + 1;
CValue.SetWindowText(strValue);

Whoops!
CString strValue;
CValue.GetWindowText(strValue);
int nValue = atoi(strValue) + 1;
strValue.Format(_T("%d"), nValue);
CValue.SetWindowText(strValue);

What about GetDlgItemInt()?
SetDlgItemInt(IDC_MYCONTROL,MyCtrl.GetDlgItemInt(IDC_MYCONTROL) + 1);
onwards and upwards...

hello together,
i have a strange problem with the following asm command;
__asm call 0h
This command should jump to the next instruction and put the value of the position where the last call was made onto the stack! Well, it should, but i only get this message:
error C2415: improper operand type
Any ideas?
Thanks in advance!
