No.. hWnd is the handle of the Main MFC application window. I will try to find the window of the CTab1Dlg.. Is there any API's to find the window of Property pages ? Am not sure, Recently i 've learnt the Property pages & implementing it .

How to write that WM_PRININT messages. I dont have any idea about that..

Guru_C++ 13-Feb-13 6:42am View

ok Thank you,.. I will check it out :)

Guru_C++ 13-Feb-13 5:17am View

Hello Maxim, Thanks for replying.. I modified this code as per as your suggestion. The snippet code looks like this:

void ScreenShot()
{
IDirect3DDevice9* pDirect3DDevice;

IDirect3DSurface9* pRenderTarget=NULL;
IDirect3DSurface9* pDestTarget=NULL;

D3DDISPLAYMODE d3ddisplaymode;

D3DPRESENT_PARAMETERS PresentParams;
memset(&PresentParams, 0, sizeof(D3DPRESENT_PARAMETERS));

PresentParams.Windowed = TRUE;
PresentParams.SwapEffect = D3DSWAPEFFECT_DISCARD;

IDirect3D9* direct=Direct3DCreate9(D3D9b_SDK_VERSION);
direct->CreateDevice(D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL,
GetDesktopWindow(),
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&PresentParams,&pDirect3DDevice);

if (pDirect3DDevice == NULL)
return;

HRESULT hr = pDirect3DDevice->GetRenderTarget(0, &pRenderTarget);

hr = direct->GetAdapterDisplayMode(D3DADAPTER_DEFAULT,&d3ddisplaymode);

hr = pDirect3DDevice->CreateOffscreenPlainSurface(d3ddisplaymode.Width,d3ddisplaymode.Height,D3DFMT_A8R8G8B8,
D3DPOOL_SYSTEMMEM,
&pDestTarget,
NULL);

pDirect3DDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &pDestTarget ) ;

hr = pDirect3DDevice->GetRenderTargetData(pRenderTarget,pDestTarget);

hr = D3DXSaveSurfaceToFile("E:\\abc.bmp",
D3DXIFF_BMP,
pDestTarget,
NULL,
NULL);

pRenderTarget->Release();
pDestTarget->Release();

}

But Still i use to get black image .. I dont know whats wrong is happening :(

Guru_C++ 13-Feb-13 2:42am View

I was able to figure out where is the problem, I came to know that I've not created the device. I changed the code like this:

// globals
LPDIRECT3D9 g_pDirect3D = NULL;
LPDIRECT3DDEVICE9 g_pDirect3D_Device = NULL;
IDirect3DDevice9* g_pd3dDevice ;

void CaptureScreen()
{
g_pDirect3D = Direct3DCreate9(D3D_SDK_VERSION);

D3DPRESENT_PARAMETERS PresentParams;
memset(&PresentParams, 0, sizeof(D3DPRESENT_PARAMETERS));

PresentParams.Windowed = TRUE;
PresentParams.SwapEffect = D3DSWAPEFFECT_DISCARD;

g_pDirect3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL ,hMainWnd,D3DCREATE_SOFTWARE_VERTEXPROCESSING, &PresentParams,&g_pDirect3D_Device);

IDirect3DSurface9* pSurface;
g_pDirect3D_Device->CreateOffscreenPlainSurface(100, 100,
D3DFMT_A8R8G8B8, D3DPOOL_SCRATCH, &pSurface, NULL);
g_pDirect3D_Device->GetFrontBufferData(0, pSurface);
D3DXSaveSurfaceToFile("E:\\Desktop.bmp",D3DXIFF_BMP,pSurface,NULL,NULL);
pSurface->Release();
}

This prevents the Access Violation error after creating the Device. But the Image is in black color. Am i missing it out somewhere.. Please point out me if am wrong..

Guru_C++ 15-Jan-13 4:11am View

yeah.. I have created two threads like this..

UINT Thread1(LPVOID lParam)
{
while(1) {
//Code for Open Operation..
}

return(1);
}

UINT Thread2(LPVOID lParam)
{
while(1)
{
//Code for Close Operation..
}

return(1);
}

void CTradingPlatform : OnBnClickedOPEN()
{
AfxBeginThread(Thread1,0);

}

void CTradingPlatform : OnBnClickedCLOSE()
{
AfxBeginThread(Thread2,0);
}

Now this works fine.. Thank you..

Guru_C++ 15-Jan-13 2:30am View

I've solved it myself .. Anyhow after a lot search on Tesseract, Finally am able to use Tesseract now.

Guru_C++ 12-Dec-12 5:04am View

I tried type casting like this..
lpszEnd =(TCHAR*) _tcschr(s, _T(' '));

It worked fine.. And am getting exact output..

Thank you..

Guru_C++ 12-Dec-12 4:55am View

Thanks for replying... But am getting this error: error C2440: '=' : cannot convert from 'const char *' to 'LPTSTR' on this line
lpszEnd = _tcschr(s, _T(' '));

Guru_C++ 27-Nov-12 0:46am View

Woh !!! Great :) It worked... Thanks Andrew..

Guru_C++ 16-Nov-12 4:19am View

Hi Eugen.. Thanks a lot for giving a hint. I guess i found the solution as u suggested to use ::IsWindowVisible(). My code looks like this:

CWnd *cwnd = NULL;
cwnd = FindWindow("SunAwtDialog","Add Open Deal");
BOOL isTrue = cwnd->IsWindowVisible();

Now.. If Add open Deal window is opened, isTrue variable contains 1.. If not opened isTrue contains 0. Based on this i can do operations on Add Open Deal window.

Thanks a lot :)

Guru_C++ 16-Nov-12 3:01am View

I used the first method i.e., assigning the hwnd variable to NULL ..The result was same.. And, i used the Spy tool to check the Window name & Class name, later i came to the class name i.e., SunAwtDialog. Now the code looks like this..

HWND hwnd = NULL;
hwnd = ::FindWindow("SunAwtDialog","Add Open Deal");

The Result is same. Eventhough the Add Open Deal is closed, hwnd contains valid address..

Guru_C++ 16-Nov-12 2:22am View

Hello Eugen.. Thanks for helping.. In my application, First window (i.e., Wing Fung ) is not pro-grammatically created. Its just like third party application. Then how to use CYourFirstWnd code ? am not getting it..

Guru_C++ 4-Oct-12 0:39am View

Thank you Chuck :)

Guru_C++ 3-Oct-12 9:42am View

Thanks Chuck .. Really i have no idea about the threads am beginner in that.. Please suggest me How do i Properly create a thread & Terminate it..

Guru_C++ 29-Sep-12 6:38am View

Thanks Wang.. But am facing a problem over here.. In Take_Screenshot() 'm just displaying a message box for testing purpose. But 'm unable to run it continuously. I mean only one time i used to get the message box, next time when control comes to gcPtr<cmfc2dlg> obj = new Cmfc2Dlg(); I used to get the error called:

Windows has triggered a breakpoint in mfc2.exe.
This may be due to a corruption of the heap, which indicates a bug in mfc2.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while mfc2.exe has focus.
The output window may have more diagnostic information.

Is there any problem with this code ?

Guru_C++ 29-Sep-12 6:10am View

Is this Correct..?? What am using here ?
void AddRef()
{
InterlockedIncrement (&refVal);
}
void ReleaseRef()
{
InterlockedDecrement (&refVal);
if(refVal == 0)
delete [] this;
}

Guru_C++ 29-Sep-12 6:03am View

Thanks Wang.. I was not knowing it was not safe.. Can u suggest me How to use InterlockedIncrement /InterlockedDecrement ??

Guru_C++ 31-Aug-12 5:09am View

sorry.. I dint understood..

Guru_C++ 29-Aug-12 8:49am View

Oh..! Thank you for the help..

Guru_C++ 29-Aug-12 1:07am View

Thank you.. This is also fine. Now am having clear idea..

Bascically am working on Project Trading application, if BUY price is less than or equalls to SELL price. I need to open the both confirmation windows by clicking both BUY & SELL buttons at the same time. Suppose, first if i click SELL button & then if i click BUY button during that time the price will be moved up.. So i tried to click at the same time. I was not sure it is possible or not. So i asked..

Guru_C++ 1-Jun-12 1:50am View

Thanks... Let me try on this..

Guru_C++ 31-May-12 10:01am View

I applied cvFindcountour() to image... I can Draw countours or like boundary line on numbers. But how do i retrieve the numbers to my application.. Is their any library for that ?

Guru_C++ 31-May-12 9:07am View

I tried this.. But am not getting exactly ..

Guru_C++ 28-May-12 1:18am View

I found an example: regsvr32 "C:\Program Files\Moon Valley Software\CD Ultra\Bin\activex\PlayList.ocx". And what is the path to register the mdivwctl.oca ??

Guru_C++ 25-May-12 9:10am View

My application is saying: This "{EF347A62-BA21-42E4-94A0-1C0A6D7FDFE7}" ActiveX control is missing. AM not getting the name of this control.

Guru_C++ 25-May-12 2:11am View

This link is absolutely what i was looking for http://www.codeproject.com/KB/recipes/OCRwithMODI.aspx.. But when i execute the source code, its giving something Debug assertion failed..
Also, in debug mode, i found that VS2008 creates a breakpoint at the following line in occcont.cpp:ASSERT(IsWindow(pTemp->m_hWnd));

Probably, After googling i found ActiveX control is not registered in ur computer. How do i register ActiveX control in MFC appliction ?

Guru_C++ 24-May-12 3:21am View

Previously my image is in .bmp format that contains some individual prices like Rs 1530.98. Using Image online converter, i converted to .emf format. Now how do i identify the header & individuals records in that ?? And also how can i read that price ? Its really a complex task..!! And, When i open the EMF file in paint , it is same as that of .bmp file ..

Guru_C++ 24-May-12 1:00am View

Thank you for replying..Really am in need of the answer.. Sure i will learn about steganography. And, If an image is an EMF file, then how can i read the contents of the image file. Can anyone explain about this..? Waiting for reply ..

Guru_C++ 2-May-12 0:28am View

Sorry.. Am not getting any answer..

Guru_C++ 2-May-12 0:28am View

Guru_C++ 27-Apr-12 0:54am View

Thank you.. It works fine... But if the setup.exe is run as administrator, then also CreateProcess wii=ll return 0 status.. Am not getting why it happens with Run as administrator..

Guru_C++ 27-Apr-12 0:03am View

FIND_PROC_BY_NAME: It determines whether the process is running or not.. If it is running then it returns 1 or else 0.

Guru_C++ 27-Apr-12 0:02am View

Yes.. I can see the setup.exe in task manager

Guru_C++ 23-Apr-12 5:14am View

yes.. Now it is working fine ..

Guru_C++ 20-Apr-12 7:15am View

Yes i tried that link.. Only progress bar is displaying.. No marquees..

Guru_C++ 20-Apr-12 6:34am View

Am not getting how to use marquee style in progress bar :(

Guru_C++ 20-Apr-12 6:00am View

As per as ur suggestion.. i used Progress bar like this..
HWND hProgressBar = NULL;

hProgressBar = CreateWindow(PROGRESS_CLASS, NULL, WS_CHILD | WS_VISIBLE,10, 20, 150, 20, hWnd, (HMENU)10001, hInstance, NULL);

But this code Does not make use of Visual styles like marquee mode..
Please can u tell me how to use progress bar in marquee mode ..

SendMessage(hProgressBar, PBM_SETRANGE, 0, MAKELPARAM(0, 100));
SetTimer(hWnd, 1, 1000, NULL);

SendMessage(hProgressBar, PBM_SETPOS, (WPARAM)100, 0);

Guru_C++ 20-Apr-12 5:21am View

char* temp=buffer2;
int buff_len=strlen(temp);
for(int i=buff_len;i>0;i--)
{
temp[i]='\0';
if(i==43)
break;
}

With this code, if i rename the "gscanner.exe" to some other name.. Then it wont work..

Guru_C++ 4-Apr-12 1:56am View

Actually, i want to generate the text file in Debug Folder.. So i need the path like this c:\Users\guruprasad\Desktop\gscanner\Debug\

So i want to remove the string "gscanner.exe"

Guru_C++ 4-Apr-12 1:49am View

Yes.. I want to remove or truncate the string "gscanner.exe"..

Guru_C++ 2-Apr-12 8:40am View

Thank you.. It is working..

Guru_C++ 2-Apr-12 7:59am View

Actually, In my Tool_a.exe Application, I have to Encrypt the Contents of the File.. And in Tool_b.exe application, I have to Decrypt the Contents of the file & it is viewed by only autheticated users.. So Am trying to Decrypt it..

Guru_C++ 21-Mar-12 7:26am View

Actually i applied to Hidden & System to .txt file, So it was still visible.
But when i used like this:

char Path[]="E:\\MyDirectory123";
BOOL success;
success = CreateDirectory(Path, 0);
SetFileAttributes("E:\\MyDirectory123",FILE_ATTRIBUTE_HIDDEN|FILE_ATTRIBUTE_SYSTEM);

Now MyDirectory123 is not Visible.Now my problem is solved. I guess Hidden & System attributes applies to Folder.

Thank you so much for helping.

Guru_C++ 21-Mar-12 6:56am View

Am using like this :
SetFileAttributes("E:\\new_locking.txt",FILE_ATTRIBUTE_HIDDEN|FILE_ATTRIBUTE_SYSTEM);
Now also the file is visible..

Guru_C++ 21-Mar-12 6:28am View

yes i used like this:
rename("E:\\locking.txt","E:\\new_locking.txt");

SetFileAttributes("E:\\new_locking.txt",FILE_ATTRIBUTE_HIDDEN);

After this, the file new_locking.txt will be hidden..

But when i go to Folder options->tools->view->Show hidden files. new_locking.txt file will be displayed. But it doesn't happen in the case of bat file. Any suggestion for this ?

Guru_C++ 21-Mar-12 5:37am View

Am having a lock.bat file that works exactly like folder lock.
lock.bat code is like this:
cls
@ECHO OFF
title Folder Locker
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Locker goto MDLOCKER

echo Are you sure u want to Lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock folder

Can anyone tell me, How can i do it in WIN32 ?

Guru_C++ 19-Mar-12 6:38am View

Ok.. Can u provide any usefull links to block all the readings from Drive using WIN32 Programmatically.

Guru_C++ 19-Mar-12 5:05am View

Yes.. I agree with this point. We can block all writing to D:Drive or block all reading from I:Drive.
Just assuming that, In I:Drive am having three .txt files. And, If we made block all reading from I:Drive, Can i copy all three .txt files to Other Drives ?

Guru_C++ 19-Mar-12 3:55am View

Actually.. Using WIN32 Programmatically, i want to make I:Drive as Copy Protect that is,The files in I:Drive should not copy to Other Drives. Am not sure can it be done like this ? Am having lot confusion about this concept, because all drives will be under Device Drivers control.. If i want to achieve this, Should i need to change Device Drivers program or what ??

Guru_C++ 14-Mar-12 8:33am View

Ok.. Thanks alot..

Guru_C++ 14-Mar-12 3:20am View

But how to avoid the Garbage value...! Am getting like this abcdefÌÌ

Guru_C++ 14-Mar-12 3:09am View

Woh...!! Cool.. It is working.. Thanks alot...

Guru_C++ 14-Mar-12 2:06am View

Atleast, Can it be done for External USB or Flash Disk ??

Guru_C++ 12-Mar-12 5:37am View

Yes.. Ur right.. In basic file attributes we don't have such options.

Guru_C++ 12-Mar-12 5:00am View

Is there any way to make it Programmatically with out using User Account Control Features..

Guru_C++ 12-Mar-12 0:38am View

After combination of all these, The file becomes Read only.. Can't chage the contents of the file.. But we can copy that file to some other location.. But how we can avoid that..! Suggest me..

Guru_C++ 10-Mar-12 1:50am View

So.. What i need to Pass for dwShareMode ..To make file as non-exclusive mode..

Guru_C++ 10-Mar-12 1:49am View

i dont want user to copy that file to some other location ..

Guru_C++ 9-Mar-12 7:56am View

And, Also i searched about LockFile in MSDN.. Can anyone tell me how to use that LockFile function..

Guru_C++ 9-Mar-12 7:18am View

Sorry... Din't got :(

Guru_C++ 8-Mar-12 7:21am View

Please, Show me with code..

Guru_C++ 6-Mar-12 23:46pm View

Thank you so much... It had worked....:)

Guru_C++ 6-Mar-12 8:28am View

I have used the ReadFile function, but actually it doesn't help me to retrieve the data .. Actually i need data from the File ...

Guru_C++ 30-Jan-12 7:56am View

Thanks..

Guru_C++ 30-Jan-12 7:48am View
