You need to handel Command Line Arguments in Your program So use public static void Main(string Args[]) Or static int Main(string[] Args) instead of parametersless Main method
look at Command-Line Arguments[^]
you need to parse this arguments to handle more complex parameters an example for this can be found at C#/.NET Command Line Arguments Parser

Take a look at the registry key SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths

Okay, I give - been all over the net and nothing comes close. You'd think this was the first time somebody cam across this in C#:
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Ansi)]
public struct AGENT_DATA
{
//[MarshalAs(UnmanagedType.LPArray, SizeConst=3000, ArraySubType=UnmanagedType.LPStr)]
//[MarshalAs(UnmanagedType.SafeArray, SafeArraySubType=System.Runtime.InteropServices.VarEnum.VT_LPSTR)]
//[MarshalAs(UnmanagedType.ByValTStr, SizeConst=15)]
//[MarshalAs(UnmanagedType.ByValArray, SizeConst=3000, ArraySubType=UnmanagedType.ByValTStr)]
public string[] m_AgentNames;
}
As you can see, I've tried several attributes - all runtime error. "Cannot obtain size of struct" when I attempt to:
int nSize = Marshal.SizeOf(agentData);
There will be no more than 3000 names, about 15 characters long.
Eventually, I'm going to: IntPtr lParam = Marshal.AllocHGlobal(nSize);
and then: Marshal.StructureToPtr(agentData, lParam, false);
finally:
Win32APIWrapper.PostMessage(
m_hMessageHandlerWindowHandle,
WM_MESSAGE,
(uint)(wParam.ToInt32()),
lParam.ToInt32());
This structure will then be consumed in a C++ module.
So... How do I Marshal a string array of "n" elements that are "l" characters?
Thanks. If you know - Go tell MSFT, so they can post it somewhere.
Note: the names are 15 ascii alphabetical characters. I'd rather avoid using BSTRs but am open to suggestions.

I wrote a simple Windows Forms app (just has one form) which runs fine on XP.
But when I try it on a Windows 98 PC, all the controls in the form are enlarged (I turned off AutoSize for my textboxes), and the font of my text labels doesn't look like what I specified in the property editor. The size of the form appears to be correct though.
Has anyone seen this before, or have any hints about making sure a form displays the same across different windows OS. I'm wondering if turning off AutoScale form property will help...

Are the fonts you use in your app installed on both platforms?
|
|
|
|
|
My form/controls are all using the default font that shows up in the VS.NET 2003 property editor. I think Microsoft Sans Serif 8.25pt. The Windows 98 PC is at a remote site, so I can't check it at the moment, but I thought the default font would be available across PCs.

Hi all, I have two tables one is Machine the other is SitePosition.
The SitePosition table have primary keys (SiteNo, PositionNo). In the Machine table, there are SiteNo and PositionNo as the foreign key reference to the siteposition table. When updating the machine table, I need to change the value of (SiteNo, PositionNo) in machine table. But because the foreign key constraint, once I change the SiteNo's value, it will give me an error say that it violate the foreign key constraint since there is no record existed in the SitePosition table. The same error happens if I update the PositionNo first. The problem seems that the foreign keys as a bunch are not updated simultaneously. Does anybody know a solution to this problem please???
Thanks in advance!!!

hi there,
here is just my suggestion: should check the constraint between these tables in business logic, not throw this task for DB server.

hi
I didn't put this into DB server, the exception occurs in the dataset. It prevents me from carrying on my tasks

just dont set any relationship between these tables in ur dataset

Try setting the EnforceConstraints property to false before and back to true after editing.

How can I auto-adjust the column width using Excel Automation?
I am extract a large dataset from a DataSet object to the Excep workbook.

We are beginning the development of applications in Visual Studio.Net and have a number of libraries written in C++. For a number of reasons we don't want to convert these to C#. Any recommendations/references as to how best to access the C++ code from C#?
Think globally act locally.....integrate by parts

Go to MSDN and do a search for "P/Invoke". I don't want to frighten you off but P/Invoke isn't exactly a beginner level topic and marshalling data types across can get hairy. You need to be sure you have your .Net and C# fundementals down first before you try to bridge to other language runtimes.

AFIK There are no out of the box method you need to deal with RTF syntax to do this look at RTF [^]

how can i read data from excell file?
|
|
|
|

If you would just search for Excel you would already have the answer...

read through a datafile store the information in primary memory and sort it in ascending order using selection sort According to course code
the data file contains a sequence of records
each record consists of several data fields stored sequentially in the order given
DATA FIELD DATA TYPE
Code String
Title String
Semester Integer
Credits Integer
Level Character
Short Description String
Previous Pass Rate Double
Must write a function char *read_string(File *fp)
to read a string from a file

I have a List of objects of type Extension. I want to search through the list looking for an Extension e where e.name = ""
How do I do this in the .NET framework? I am confused on the proper syntax.
Thanks,
Lilli

Okay, so you've got a list that looks like this:
List<Extension> myExtensions = new List<Extension>();
Then you'd just iterate over it and find the one where e.name == "".
foreach(Extension e in myExtensions)
{
if(e.Name == "")
{
}
}
