Hi
I am trying to open a file for reading using C++ I/O. The call to read is simple
#include <fstream>
using namspace std;
int _tmain()
{
std::string infile(_T("testreport.txt"));
ifstream fin(infile.c_str(), ios::in);
if(!fin)
{
cout << "unable to open file for reading";
}
return 0;
}
when I execute the program I always get the failure. However if I specify the full path to the file like "d:\\testdata\\debug\\testreport.txt", I am able to open the file successfully.
I am using VC++ 2005 compiler and debugging with in VC IDE. How do I make VC++ to automatically take the relative path of the file.
This problem only occurs when I am debugging through the VC++ IDE.
Thanks and Regards

First it has nothing to do with Visual C++. You are using a library called STL to open the file. It uses the OS support to open the file and they both support relative paths. But just like an absolute path you have to get the relative path correct or it won't work.

You have to configure your IDE to use d:\testdata\debug as working directory when debugging. On Visual Studio 2005, for instance, select Project->Properties menu item and then (on the newly appeared window) select the Configuration Properties->Debugging node, select Working Directory item (on the Local Windows Debugger) list and finally assign it the d:\testdata\debug path.

I don't think so.
Anyway now it works, why bother?
Best wishes.

I wrote an ActiveX control. At first there was no GDI+ code in it and it worked well. Then I added follow code:
class ATL_NO_VTABLE MyControl:
public .........
{
...
BOOL OpenImageFile(BSTR FilePath) // added a method
{
USES_CONVERSION;
m_pBitmap = Bitmap::FromFile(FilePath);
return m_pBitmap!=NULL;
}
Bitmap *m_pBitmap; // added a point
}
After I added a point and a method, MyControl was no long created successfully. I searched in www.codeproject.com and finded Ryan Johnston's article----http://www.codeproject.com/KB/GDI-plus/gdipluscontrol.aspx, I read the article and thought it would resolve my problem, en..., it didn't.
It's very strange that after I remove my method, MyControl can be created, but if I add "static InitGDIPlus GDI_Plus_Controler;" in MyControl.cpp, MyControl can not be created again. I have not call the object's method yet, only declare a static global. Why this declaration make MyControl create failed?
I hope someone can help me resolving this problem. Suggestion, article, code example, anything may be helpful is appreciated, thank you.

Sounds like you're missing gdiplus.dll. That didn't come with Win 2K.

We have two EXE. one COM EXE.
when calling some methods written in COM EXE, shows the following message.
What is the exact problem?
" This action cannot be completed because the other program is busy.
Choose 'Switch To' to activate the busy program and correct the problem"
|
|
|
|

Many things can cause this...
1. Your COM server or Main thread died
2. Main thread is processing a long operation

Hello,
I am naive to Windows Services.
I have few queries regarding Windows Services which are as follows: -
How to manage User account?
For example there are several users present on a single machine and how to restrict users group from accessing the Windows Service?
Can do it using CoInitializeSecutriy(), if yes then How?
Thanks in Advance.

The obvious answer is to use the Windows User Management tool. If you want to develop your own software to do that it is going to be far more complicated that using a couple of API calls. If you want to do Windows Security development I suggest you find a good book that covers that topic in depth.

Hey Led,
Yes i am looking for Windows Security Management.
Can you please tell me the name of that book?
Thanks!

Hello Friends,
I have developed one ATL com dll for IE tool bar.
My Ie toolbar is having buttons which i have created dynamically.
buttons are having Icon images also.
but i am facing one problem...
I can show only the Icon with "Bit Depth=8" of .ico image.
Actually i want to show Icons with "Bit Depth=32" also.
I am using below code..
UINT colormap = LR_DEFAULTSIZE |LR_LOADMAP3DCOLORS| LR_LOADFROMFILE | LR_CREATEDIBSECTION|LR_LOADTRANSPARENT;
HBITMAP hBitmap =(HBITMAP) ::LoadImage ((HINSTANCE)::GetModuleHandle(NULL),ImagePath,IMAGE_BITMAP,0,0,colormap);
In above code...
while Debugging i came to know that i am getting null in hBitmap variable for Icons with "Bit Depth=32". for Bit Depth up to 24 it is working fine.
Please suggest me the solution....

Why are you using IMAGE_BITMAP if you're trying to load icons?
You should try IMAGE_ICON.
Hope it helps

Yes i am now using IMAGE_ICON.
it is workin fine...now I can add Icon with 32 bit Depth in my image list.
I observed one more thing that IMAGE_BITMAP works for icons also...but for icons with Bit Depth upto 24 only.
Thank you...

Hi Friends,
I am using VC++ 6.0 I careated an exe server using ATL. It has one interface mdethod "ComputerName". Prototype of method is :
[id(1), helpstring("ComputerName")] HRESULT ComputerName([out] short *pnSize, [out, size_is(1, *pnSize)] unsigned char **ppszComputerName);
Server implementation of this function is :
STDMETHODIMP CTestServer::ComputerName(short *pnSize, unsigned char **ppszComputerName)
{
TCHAR szBuffer[100] = {0};
DWORD dwSize = 0;
int iLength = 0;
dwSize = sizeof(szBuffer);
GetComputerName(szBuffer, &dwSize);
iLength = ::lstrlen(szBuffer);
*pnSize = iLength;
*ppszComputerName = (unsigned char *) CoTaskMemAlloc(iLength + 1);
::lstrcpy((char *) *ppszComputerName, szBuffer);
return(S_OK);
}
Client Side Implementation is :
ITestServer *pITestServer = NULL;
HRESULT hResult = NULL;
short int nSize = 0;
unsigned char *pszComputerName = NULL;
CoInitialize(NULL);
hResult = CoCreateInstance(....);
if(SUCCEEDED(hResult))
{
pITestServer->ComputerName(&nSize, &pszComputerName);
// Here is problem only pszComputerName[0] contains valid data. other contains invalid data. nSize contains valid length.
pITestServer->Release();
}
CoUninitialize();
I am unable to get the reason. Anyone can help me please.

Hi Manish,
If you want to pass string, use BSTR. COM marshalling works a bit different.
If you plan to transfer 'byte*', use Safearray of byte.

Thanks Ernest Laurentin
BSTR is working.
