No you can insert SS_BITMAP with ModifyStyle to your control and for bmp files you can use of this function but for jpg files you need to use of CImage class.

Assume prfimg Bitmap is proper.
EncoderParameters pEncoderParameters;
pEncoderParameters.Count = 1;
pEncoderParameters.Parameter[0].Guid = EncoderCompression;
pEncoderParameters.Parameter[0].Type = EncoderParameterValueTypeLong;
pEncoderParameters.Parameter[0].NumberOfValues = 1;
ULONG compression = EncoderValueCompressionRle;
pEncoderParameters.Parameter[0].Value = &compression;
GetEncoderClsid(L"image/tiff", &encoderClsid);
st = prfimg->Save(L"i:\\m\\img.tif", &encoderClsid, &pEncoderParameters);
getting value of st as InvalidParameter and the image is not saved properly on disk(saved image size on disk is 1KB)
Please tell if something more needs to be done to save tif image with Rle compression.
Other compression options gives the same InvalidParameter result.
Thanks and Regards.

I have added the key in HKLM on Xp64bit OS.
HKEY_LOCAL_MACHINESOFTWARE\\TEST\\App\\MyKey === "CodeProject"
Now, I have tried with below mentioned way,
bool Result = RegOpenKeyEx(HKEY_LOCAL_MACHINE, TEXT("SOFTWARE\\TEST\\App"), 0, KEY_READ, &hKey) == ERROR_SUCCESS;
if (Result)
{
Result = RegQueryValueEx(hKey, TEXT("MyKey"), NULL, &dwType, (LPBYTE)&szTemp, &dwSize) == ERROR_SUCCESS;
switch(dwType)
{
case REG_BINARY:
AfxMessageBox ("\ntype: REG_BINARY");
break;
case REG_NONE:
AfxMessageBox ("\ntype: REG_NONE");
break;
}
}
Messagebox displays"type: REG_NONE". That means, "No defined value type".
So, how to get my key (MyKey) value "CodeProject"?

This must be if (ERROR_SUCCESS == Result)
and Result must be declared as a LONG and not bool.

That works fine only. I am talking about "dwType"

The value of ERROR_SUCCESS is 0.
So, in you code if it is entering if(Result), it means you are not getting ERROR_SUCCESS, which means an error in the open itself.

I got the solution. If our application is 32bit then registry entry (only for HKEY_LOCAL_MACHINE) in 64 bit OS sould be in
HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node
in my case entry should be in
HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Test\\App

It is most likely because you did something wrong.

but seriously, give some code, more details, otherwise noone will be able to help you.

How are you 'Calling Timer' (you know, no code => no help...  )?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

CString a1[aq] is external vaiable.
Plz help me

- Please check the posted code (for instance use
< to escape the symbol < when required). - Why are you calling directly the timer function inside
OnInitDialog (instead of starting the timer? You may actually do it, but usually you haven't...)? - Since you're calling directly (form
OnInitDialog) your timer function (OnBnClickedTimer) it doesn't make sense the OnStopTimer call in the latter.
Anyway your application 'freezes' possibly because of a bug in your loop. You should debug it in order to have a clue about (ispecting your code is also difficult because of the, already mentioned, bad formatting).

Yes, you are right, of course.

I want to open all files with a certain name and/or a certain type, but for that I need to know the contents of a directory first.
How do I see them?
Thanks.

FindFirstFile and FindNextFile should do it.

Thanks.
I got something (I think) with FindFirstFile and FindNextFile.
Though, it doesn't quite work, this whole code is in a try catch block, but still throws a System.AccessViolationException (which is .NET specific and I can't use it or acces it) and does nothing:
try
{
fstream file;
vector<lpwin32_find_dataw> files;
LPCTSTR namepointer;
HANDLE handle;
string line = "";
int i = 0;
int size;
char directory [] = "C:\\Folder";
char *stringpointer = directory ;
files.assign(1, LPWIN32_FIND_DATAW());
handle = FindFirstFile(namepointer, files[i]);
while (handle != INVALID_HANDLE_VALUE)
{
FindNextFile(handle, files[i]);
files.assign(1, LPWIN32_FIND_DATAW());
i++;
}
size = files.size();
cout << files.size() << endl;
for (int k = 0; k < size; k++)
{
cout << "Reading File:" << files[k]->cFileName << endl;
}
getchar();
return 0;
}
catch (exception ex)
{
cout << "An error has occurred." << endl;
cout << ex.what() << endl;
}</lpwin32_find_dataw>I want to read the filenames to check if they're txt files with the right kind of name and then read from them to process the text of each.
Thanks.

Where/when?
Why do you have a vector of WIN32_FIND_DATA structures? One is sufficient.
Megidolaon wrote: handle = FindFirstFile(namepointer, files[i]);
What is the value of namepointer?

It throws the exception right at the start and does nothing else.
DavidCrow wrote: Why do you have a vector of WIN32_FIND_DATA structures? One is sufficient.
FindFirstFile and FindNextFile seemed to return only as single file, so I assumed LPWIN32_FIND_DATAW represented a single file.
How does that work anyway?
The struct only has a few attributes that seem like file attributes, which wouldn't make much sense in a collection (like filename or creation date).
Originally I had
namepointer = stringpointer; but that won't do.
I get an error that char* cannot be converted to LPCTSTR.
I must have deleted the line and didn't notice.
Though, it was done like that in the article Hamid posted (then again, I got 10 errors from that code).

It does, hence the need for a loop.
Look through this snippet to see where you went awry:
vector<string> files;
WIN32_FIND_DATA findData;
BOOL bFound = TRUE;
HANDLE handle = FindFirstFile("C:\\*.*", &findData);
if (handle != INVALID_HANDLE_VALUE)
{
while (bFound)
{
files.push_back(findData.cFileName);
bFound = FindNextFile(handle, &findData);
}
}
for (int k = 0; k < files.size(); k++)
cout << "Reading File:" << files[k].c_str() << endl;

Thanks, though this code stil throws 2 errors.
First one that I can't convert from const char[7] to LPCWSTR (in FindFirstFile).
Second one is that I can't convert from WCHR[260] to std::string & (files.push_back(findData.cFileName);).

That's because you are using Unicode. Change string to wstring and prepend the string literal with an L.
