Hi,
I've created a console application and want to hide the (console) window when the app. is started. I know you can achieve this by calling 'ShellExecute', but that's not what i want. I remember i did this at one point by using '#pragma comment (linker , *bladiebla*)'. I don't exactly remember the rest, but i think it was something like that. Can anbody help me out here?
Thanks

You can do the same thing in project settings->link/catagory output Entry-point symbol.

HI,
I have a program that is loaded in memeory and i know its memory address , so how can i launch/Run that progrmam without using ShellExecute(..) etc.
thanx

i don't understand the problem but here is a solution may be it is what u want
from ur program load another program in YOUR memory not by ShellExecute or anything simply read the file and store the contents
then simply do a jump to that address
_asm jmp (wherever u want)
don't forget to call jmp or ret from the loaded code to ur own code so u can exit properly
Hope all this makes sense

I dont thing this is going to work with exe files, for exe file you need to recalculate the far calls present in the exe file also rebasing problem needs to be taken care...
Your solution is rite but for .COM files.

The Guy originally wrote :

i don't see any mention of exe or any com file , The program in memory can be just a chunk of asm instructions not necessarily an exe in PE format ,
Still the PE Header of the Executable can be patched accordingly to match the Loaded DLL's in memory

The guy did not mention that how he had loaded the code into the memory. If assumed that he had loaded using readfile then no way he can execute the PE file or .exe file. But a .COM file can be exectued but dont know how it is going to function in windows envirionment.
Plus, lot of things are not known like was the stack, process id, sperate LDT, etc allocated for the code that has been loaded.
Over all according to me the Question is quite nonsence. Why anyone wants to play god when windows is there. Only person i can think of are virus writers.they want to imitate the OS to do some background job.

How do you load the pop-up (child) dialog before the program like the login screen?
|
|
|
|
|
You need to call dialog in
BOOL CMyClass::InitInstance()
{
CChildDialog dDlg;
dDlg.DoModal()
.
.
.
.
}

I have a socket i am using normal blocking sockets (brekley sockets). I want to know before i call recv wheather it will become a blocking one or not. so that the socket dont block at that instance coz it is causing threading locking.
Is there any way to provide a timeout to the sockets..
i am not using MFC and so mfc CSocket is not a solution.

Try using "select" call+FD_SET

Thanx i guess this will solve my problem..

Hi,
I have a CScrollView set up in one pane of an MDI splitterwindow application.
I would like the user to be able to scroll the view by clicking inside the CScrollView then dragging the mouse outside the client area. To see an example of what I mean, load up ms excel, click on a cell, then drag outside the child window (or outside the main frame of the application).
I thought I could do this by using "onmousemove" messages, calculating which way the user has dragged, and scrolling accordingly, but unfortunately I can't receive mouse coordinates when the user is outside the client area, and I only want the scrolling to occur when the user has dragged off the side of the CScrollView.
Any help would be GREATLY appreciated, thanks for your time.

You can use OnMouseMove() but you'll have to call SetCapture() first to capture the mouse input. Make sure you call ReleaseCapture() when you've finished.
Hope this helps,

/ Initialize data form parameters
char* szFileName = argv[1]; // bitmap image's file name
// Bitmap image container
CBMPImage SrcImage;
// Loading bitmap image from file
bool ResLoad = SrcImage.LoadBMP24Image(szFileName);
Can someone explain to me wat this part of the code means..I have been trying to find out which part of this code i should change to put in my own image file

char* szFileName = _T("C:\\myfile.bmp"); should do it.

i just want to know if this is possible to have another View Class in MDI and make some Child window that uses this View Class.
for example a list classes in a MDI:
CChildFrame
CMainFrame
CMyDoc
CMyView -> base class are CView
CMy2View -> i added this View Class that its base is not the same as CMyView base class and i want to have a Child Window that use this view class.
is this possible or any suggestion?
thanks in advance.

i findout smthing, i have to set a Base class to both CMDIChildWnd and my own base class. and it seems that i have to Set BEGIN_MESSAGE_MAP(CMy2View, CMDIChildWnd)
is it true that the only way that a Child Window obey a View class is to make it with this line : CMDIChildWnd::Create(...)
So to having a ChildWindow i have to set base to CMDIChildWnd and then i will lose my own base class, i mean i cant use OnPaint() Coz i have to set Message map to CMDIChildWnd. 
Any Suggestion ?

I am working on an external device that I'm trying to interface through the parallel port. To get adequate speeds, I'm looking to use EPP instead of regular CENTRONICS. The problem is, I get the following output when I try to write to the port after negotiating the protocol.
<br />
Opening LPT1... OK<br />
Querying LPT1 Status...<br />
Status: 80<br />
Setting EPP Mode...<br />
Querying LPT1 Mode...<br />
Read Status: 40<br />
Write Status: 40<br />
Sending data...<br />
Error: Incorrect function.<br />
<br />
Sent 0 values<br />
Sending complete...<br />
The Read and Write status indicate that I've negotiated to EPP. However, I get the shown error. Here is the code snippet of what I'm doing
<br />
printf("Opening LPT1...\t");<br />
hParPort = CreateFile("LPT1", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);<br />
<br />
printf("Querying LPT1 Status...\n");<br />
PAR_QUERY_INFORMATION ParInfo;<br />
DeviceIoControl(hParPort, IOCTL_PAR_QUERY_INFORMATION, NULL, 0, &ParInfo, sizeof(ParInfo), &ret, NULL);<br />
printf("Status: %x \n", ParInfo.Status);<br />
<br />
printf("Setting EPP Mode...\n");<br />
PARCLASS_NEGOTIATION_MASK parMode;<br />
PARCLASS_NEGOTIATION_MASK parModeBack;<br />
parMode.usReadMask = EPP_ANY;<br />
parMode.usWriteMask = EPP_ANY;<br />
DeviceIoControl(hParPort, IOCTL_IEEE1284_NEGOTIATE, &parMode, sizeof(parMode), &parModeBack, sizeof(parModeBack), &ret, NULL);<br />
printf("Read Status: %x \n", parModeBack.usReadMask);<br />
printf("Write Status: %x \n", parModeBack.usWriteMask);<br />
<br />
printf("Sending data...\n");<br />
<br />
if(!WriteFile(hParPort, data, 1, &ret, NULL))<br />
{<br />
}<br />
printf("Sent %d values \n", ret);<br />
printf("Sending complete...\n");<br />
CloseHandle(hParPort)<br />
Any ideas as to why I get an invalid function and what I can try instead of WriteFile?
