But obviously not somewhere that the code that used the items was able to see them.

If you posted some more detail (the filename that you put the template class & function declaration in, the code that uses the matrix and function), then possibly. However, your code is syntactically and semantically correct - you've just organised it so that the code that uses those things can't see them. Check through your code to understand why!

hi all,
i have written a small service.now when i install the service, the service gets installed what i feel but is not able to start. using an installer i am installing the service application in windows vista.
it gives out an error during installation, when the service is getting started.
it throws an error as follows:
Create process failed: error code 14001. the application has failed to start because the application configuration is incorrect. reinstalling the application may fix the problem.
i tried reinstalling, however the same problem persists...
i am pasting the code below,, for initial main, service installation and service start functions..please can i get some help on fixing the error....

Thankuou...

No need to paste the full code of your application. Please read the posting guidelines ("How to get an answer to your question") before posting...
For your problem: are you using VC2005 or VC2008 ? If yes, you have to instal the VC redistributable package on the target platform. This will install the C-runtime and MFC libraries.
You can find this for VC2005 here[^]. IF you need another version of VC (2008, or with a service pack installed), you'll have to search a bit on the website.
|
|
|
|
|
Or you can build you application with Static MCF and CRTL libraries instead of using DLLs. Base distribution for Vista does not include the VS2008 runtime yet.
|
|

i am using vs2008.
i did install the redistributable package on the machine..and still the same problem persists....
|
|
|
|
|
Did you install the redistributable package for VC2008 ?
Otherwise, as someone else mentioned, another solution would be to statically link to the C-runtime and MFC dlls.

Code Block 1
int iWindExtX = 3500;
int iWindExtY = 4375;
pDC->SetMapMode (MM_ISOTROPIC);
pDC->SetWindowOrg(0,0);
pDC->SetViewportOrg(0,0);
pDC->SetWindowExt(iWindExtX , iWindExtY);
pDC->SetViewportExt(972, 1404);
m_pDC->Rectangle(0, 0, iWindExtX, iWindExtY);
Code Block 2
int iWindExtX = 2500;
int iWindExtY = 4500;
pDC->SetMapMode (MM_ISOTROPIC);
pDC->SetWindowOrg(0,0);
pDC->SetViewportOrg(0,0);
pDC->SetWindowExt(iWindExtX , iWindExtY);
pDC->SetViewportExt(972, 1404);
m_pDC->Rectangle(0, 0, iWindExtX, iWindExtY);
In the above two code blocks the window extend size only differs.
My question is whether drawn rectangle using above two code blocks are of same size?
If differs then please tell me how?

Hello to all,
can anyone provide me the different IOCTL codes for FTDI driver. I am using FT232BM chip and want IOCTL codes of FTDI driver to change lattency time of the driver.It is really very urgent so plz help me out.
Thanks and Regards,
Anay
|
|
|
|
|
Don't you have some kind of documentation which was supplied with the chip ? I'm afraid those codes are specific to the manufacturer so, unless somebody already worked with this chip, nobody here will be able to help you...
|
|
|
|

As Cédric already mentioned above and I mentioned here[^], you should consult the vendor, or FTDI in this case, and the documentation they provide.
Iain Clarke suggested nearly half a year ago here[^] that you should use the D2XX solution since it is easier to use. The API of the DLL documented in this PDF[^] also contains a function called FT_SetLatencyTimer() and I think it would reasonable to assume that the function does set the latency timer...
I guess I must have misunderstood something because all I did was to Google for "FTDI" and the first hit was the home page of FTDI where I found this, to my understanding, useful information.

Hi All,
Please help me in this issue...
///using vc++///
I want to get the C M Y K values from a tiff file. I already getting the RGB values using Image class(gdi +).. Please share your ideas..
Regards,
Spk
|
|
|
|
|
You don't need to get the CMYK values directly from the TIFF file if you already have the RGB values, because the RGB values can be converted to CMYK values. You can find an information for this conversion here[^].

No problem man! Cheers!

CMYK colors are device-specific. doing the simple RGB->CMYK conversion (as linked in the reply above) is an approximation to CMYK, but not a very good one. it will be OK for some images, but total crap for many.
if you want to convert RGB to CMYK with any kind of accuracy and consistency, you need to know two things: the color profile of the device that created the RGB image and the color profile of the device that will render the image. then you can use a CMS (Color Management System) to convert between the two.
MSDN[^]
i've had good luck with little CMS[^]

Thank you for this useful information Chris!
In the past i've been done some RBG->CMYK conversions and everything was OK.
But now I understand that this was an approximation and I was a lucky man.
Thanks again!

It seems like Microsoft's image functions will read a CMYK file, but it's immediately converted to RGB. Aurigma.com makes class libraries that will read CMYK images as CMYK, without conversion. Their class libraries also provide image processing and conversion.

Hi All
I am geting debug assertion failed Line 3232 in file dbcore.cpp.Code is here
Database database;
try
{
if(database.OpenEx(_T("Driver={MySQL ODBC 5.1 Driver};Server=localhost;Database=;User=root; Password=root;Option=3;"), CDatabase::noOdbcDialog))
{
AfxMessageBox("Connection Successfully");
CString szSql = "SHOW DATABASES";
CRecordset rs(&database);
rs.Open( CRecordset::forwardOnly, szSql);
while (!rs.IsEOF())
{
CString szBuf;
rs.GetFieldValue("DATABASE", szBuf);
rs.MoveNext();
}
rs.Close();
}
}
catch(CException *e)
{
AfxMessageBox("Connection Failed");
}
i am geting assertion in this line
rs.Open( CRecordset::forwardOnly, szSql);
Debug assertion failed Line 3232 in file dbcore.cpp.
I see line 3232 in dbcore.cpp file.There i found this syntax

Can any one tell how can i solve that debug assertion.
