Hi,
Drakelor wrote: when the file size is around 255 KBytes it's all ok, but when the file is greater there is an error on "RecordSet.Update() phase. The error is : "The Pointer Value type Text, NText or image conflicts with the specified column name. ..."
You are probably storing the file into a BLOB column. All SQL columns usually have a maximum size. The error message is probably correct... if you attempt to stuff 256 KBytes into a 255 KByte data field you will obviously get an error.
I suspect that you need to regenerate your database tables. This time choose a larger column size.

I finally resolved the issue. I explain to you.
1) Download last SQL server driver.
2) Rebind/Recreate the CRecordset, so it bind with varbinary(max) -> CBYTEARRAY
3) In Recordset Class in the line : RFX_Binary(pFX, _T("[FileData]"), m_FileData,15360000);
increase the last parameter to desidered max dimension (15MB in my case).
4) Write this simple code:
CFile cfFileToSave(szPathFileToOpen,CFile::modeRead);
rsAttachments.m_FileData.SetSize((INT_PTR)cfFileToSave.GetLength());
cfFileToSave.Read(rsAttachments.m_FileData.GetData(),(UINT)cfFileToSave.GetLength());
cfFileToSave.Close();
rsAttachments.SetFieldDirty(&rsAttachments.m_FileData,TRUE);
rsAttachments.SetFieldNull(&rsAttachments.m_FileData,FALSE);
rsAttachments.Update();
All done thanks all

A few possibilities come to mind.
- Choose a different subject, one that you do understand.
- Research the use of UDP sockets, and how to write your own data management protocol.
- Switch to TCP and research some of the many samples available on the internet.

Hi!
i am New Programmer of C++. please tell me how to Use Vector In Template With Return Type.Give Me Any Example With Detail Which Can Help Me In Understanding Of This Problem.

You need to be clearer about what you mean by this. There are many samples of vectors, templates and return types to be found on MSDN[^], CodeProject articles and through Google. However, if you have a specific coding issue then please show your code and expalin what errors you have.
|
|
|
|
|
e.g.
template <typename T> T find_max(const vector <T> & v)
{
}
However, as pointed out by Richard, there are many, many possibilities, without further details cannot help more.

I have to ask: why is it that Richard is leanings sideways in your response? Are you implying he's drunk?

I have a prn file which prints bar-code. How can change the barcode value through File IO streams in VC++ 6.0
Kindly help me.
|
|
|
|
|
Can you tell what effort you put do this till now?
|
|
|
|
|

In order to replace content you have to recognize it. That is you have to write a (possibly simple) parser for the PRN file you are dealing with.
If the specifications of such PRN format are available then check them out, otherwise you have to (if possible) reverse engineer it.

1. google for barcode reader source code
2. google for barcode printing source code
3. feed the former with your .prn file and get the code it represents
4. feed that to the latter to generate a new .prn file.

Hello Everyone!
Please Tell Me How To CONTROL KEYBOARD ARROW key and Move Any Object Through Keys in C++,Please Tell Me If Any One Have Knowledge Abut this.
|
|

Add some code to handle keyboard input[^] and adjust your object's position depending on which key is pressed.

Are you wanting to "click" the arrow keys programmatically, or are you wanting to handle key clicks?

I saw this code snippet on a web page that was talking about CUDA[^] cores:
Does anyone know the meaning of the syntax on the third line where they call the kernel function with those greater-than and less-than signs?
dim3 blockDim(16, 16, 1);
dim3 gridDim((width + blockDim.x - 1)/ blockDim.x, (height + blockDim.y - 1) / blockDim.y, 1);
kernel<<< gridDim, blockDim, 0 >>>(d_data, height, width);
cudaUnbindTexture(tex);
}
__global__ void kernel(float* odata, int height, int width)
{
unsigned int x = blockIdx.x*blockDim.x + threadIdx.x;
unsigned int y = blockIdx.y*blockDim.y + threadIdx.y;
if (x < width && y < height) {
float c = tex2D(tex, x, y);
odata[y*width+x] = c;
}
}
The difficult we do right away...
...the impossible takes slightly longer.

I have n no of objects of a class. So what I want to do is - I want to save those data to a file when my application exit.
So how it is possible to write multiple objects of same class to a file and read that file to make objects of the same class.
Thanks in advance.

Google "C++ Serialization"
There are many ways to do this; but it seems using the Boost serialization library is widely recommended.
I'd rather be phishing!

Or VARIANT, if it's Win32.
