Hi!
I'm running WinXP w. VS 2005 Beta 2. And I'm trying to build my C++ MFC project from the command line.
I searched on msdn how to do this in VS 2005 ( in VS 6 I just made an .mak file and did nmake ) and the suggested method seemed to be by using msbuild. Now this seems to be a good thing but whenever I try to build my project with:
msbuild mysol.sln
this gives me warning: MSB4098 that means that project-to-project dependencies don't work. but this is not an issue since I only have one project. But msbuild doesn't compile the sources correctly it seems that the build order is all messed up since it's complaining about missing base classes.
I've also tried:
devenv mysol.sln /build "Win32|Release"
That basically gives me the same errors as msbuild does.
I really need to build my projects from the command line! Is there an easy solution for this ( I'm just doing it wrong perhaps ) or is this a bug in VS 2005 beta 2?
cheers

Search for 'Excel automation'. Google is your friend[^]

In addition to automation, you can also use ODBC.

In addition to the other methods suggested you could also use ADO to connect to the excel document as data source.
Hope this helps!

Hi everyone,
I was not sure which forum this question really belongs to. However, here goes....
I have a program running under Windows XP that communicates with a hardware device through the parallel port. Now what I want to do is write a program that can read/write messages to that port (basically remove the hardware physically and simulate it through software). However, in documentation I read that the COM port is always opened with an exclusive access. Does anyone know if there is a way to bypass that or maybe I have interpreted the documentation in a wrong way.
Cheers!

Dear All...
I have problems in avoiding memory leak. I've browsed through the message board regarding memory leak, but still can not find solution.
I have this function:
void CPA003Dlg::doMultiplyT(double **A, int M)<br />
{<br />
double temp_Sum = 0;<br />
double **B;<br />
B = new double *[M];<br />
for (int x=0;x<M;x++) B[x] = new double [2];<br />
for (x=0;x<M;x++) {<br />
B[x][0] = A[0][M];<br />
B[x][1] = A[1][M];<br />
}<br />
<br />
for (x=0; x<2; x++) {<br />
for (int y=0; y<2; y++) {<br />
for (int z=0; z<M; z++) {<br />
temp_Sum += (A[x][z]*B[z][y]);<br />
}<br />
P[x][y] = temp_Sum;<br />
temp_Sum = 0;<br />
}<br />
}<br />
<br />
delete []B;<br />
B = NULL;<br />
<br />
}
what should I do?
thanks...

i guess this is not what you wanted to type...
so, use the little [Modify] link at the botton of your post and there, uncheck the Ignore HTML tags in this message checkbox...
thanks

Your use of a 2D array is incorrect. Try:
double **B = new double*[FirstDimension];
for (int x = 0; x < FirstDimension; x++)
{
B[x] = new double[SecondDimension];
for (int y = 0; y < SecondDimension; y++)
{
B[x][y] = 0.0;
}
}
...
for (x = 0; x < FirstDimension; x++)
delete [] B[x];
delete [] B;

Hi
use CDatabase
.Open() to open database
.ExecuteNonQuery() to execute insert, update, delete statements
use CRecordset to execute select statements
Hope this helps
