Firstly, are you using Windows Security (trusted connection) or SQL Server security (you have a separate username and password for SQL Server)?
Does everyone who's going to use your application access SQL Server the same way? Do all your users have access to SQL Server?
These are the things that you need to determine before going forwards. If everyone in your workplace has a trusted connection to SQL Server and access to the DB, then you don't need to provide username and password information in your connection string. Otherwise, you'll have to get a username and password from each user (to include in the connection string) before they can get access to the SQL Server DB.
I hope this helps.

Hi,
I often end up with a collection of items I have to process. Say - an arraylist of "commands". I want to process these command and then delete the command from the collection. As you cannot modify a collection during a foreach, I often process it in reverse and delete the last (just processed) item like this
lock (col)
{
for (int i = col.count-1 ; i <=0 ; i--)
{
processItem(col[i]);
col.RemoveAt(i);
}
}
Is there a better way to do this ?

Maybe something like that:
while(col.count > 0)
{
processItem(col[0]);
col.RemoveAt(0);
}
But I am not sure it is a better way

Since processItem() doesn't know anything about the commands in the collection (other than the one it's processing), you might consider simply doing this:
lock (col) {
foreach (Command c in col)
processItem (c);
col.Clear();
}
If Command is a heavyweight object, you could try this approach:
lock (col) {
for (int i=0; (i < col.Count); i++) {
Command c = col[i] as Command;
processItem (c);
col[i] = null;
}
col.Clear();
}

Thanks - I overlooked that I had to lock the collection anyway, so I could just as well use the topmost example. Thanks again !

You'll have to be more specific than that. What is the blog software? - some provide webservice access which you can use, others don't.

If the process of posting an entry is performed via a web form, you can harness the "post entry" functionality by creating a WebResourceProvider[^].

View the source of the html page that allows you to post your blog entry. It's likely to be a form of some sort. Then, write a web resource provider[^] to mimic that action. See the GoogleTranslator[^] article for an example.

I'm having trouble saving a workbook. I show a SaveFileDialog, the user specified where he wants to save the file, and where. When the user clicks on Save button, I say SaveAs... and do something else with the file (after the file is saved). Anyway, that's what it should do.
My code for saving is this:
this.SaveAs(fileName, Excel.XlFileFormat.xlXMLSpreadsheet, missing, missing, false, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, missing, false, missing, missing, true);
It simply doesn't save the xls file. Does anybody have any idea why?

I have a bit of a problem trying to use a C++ class that contains virtual functions though C# p/invoke. Here is a trivial simplification of the problem to illustrate the issue.
With Visual Studio.Net 2003:
If I have a C++ class like so:
class ClassA
{
ClassA(){n = 0;}
int n;
void F(){n++;}
};
And an exported function that uses this class like so:
extern "C"
{
__declspec(dllexport) void ExportedFunc(ClassA** ppA)
{
ClassA* pA = *ppA;
pA->F();
}
}
I can call into this from C# by declaring a mapped structure for marshalling like so:
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)]
public class ClassA
{
int n;
}
And a function to wrap the exported C function:
class DLLImports
{
[DllImport("ExportFuncs.dll",
EntryPoint="ExportedFunc",
SetLastError=true,CharSet=CharSet.Unicode,
ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern void ExportedFunc(ref ClassA refA);
}
I can then make a call into the dll containing the exported function like so:
{
.
.
ClassA refA = new classA();
DLLImports.ExportedFunc(ref refA);
.
.
}
Okay so this works a treat.
But if I now modify classA so this it contains a virtual function like so:
class ClassA
{
ClassA(){n = 0;}
virtual ~ClassA(){}
int n;
void F(){n++;}
};
We run into a problem. The C++ class ClassA now has an extra four bytes at the beginning to contain the vTable pointer. So this needs to be taken into account when creating the structure layout in C#. Now I have tried just putting a dummy four btyes in at the beginning and I have tried changing the class to LayoutKind.Explicit and
using the FieldOffset to offset the first item in the class by four bytes, but I still find that when the code gets into the C function the vtable pointer has been reset to null.
Is there a way to overcome the problem or is is simply a case of "don't use classes that contain a virtual function with p/invoke?
Regards
