Hi, All:
I'm writing a Windows Form client that utilizing DIME to invoke a web service layer on the server that in turn exposes Visual SourceSafe's COM interface.
The ObjectDisposedException occurred whenever I try to invoke more than one web method after I open the SourceSafe's database. I always receive "Can not access a closed file". The above mentioned exception is occurred in mscorlib.dll. Does any one knows how to find out about the file that causes this exception? Any advise will be greately appreciated.

Hi,
I need help in asp.net C# programming.
I have a requirement to add a picture and data table to Excel sheet programmatically from a C# asp.net application.
I am using Windows 2000 Server with Office XP installed.
Additionally I also installed Office XP PIA's (available as download in Microsoft site).
I have added Microsoft Excel 10.0 Object Library & Microsoft Office XP Web Components (COM) references to the project.
There is no probelm exporting data to the xlsheet.
I have a probem when I add picture to the xlsheet.
Following is the code, I am trying to execute.
using Excel = Microsoft.Office.Interop.Excel;
using OWC10;
private void Button1_Click(object sender, System.EventArgs e)
{
try
{
Excel.Worksheet xlsheet1 = new Excel.WorksheetClass();
OWC10.ChartSpace objChartSpace = new OWC10.ChartSpaceClass();
addPictureToExcelSheet(objChartSpace,xlsheet1);
xlsheet1.SaveAs(Server.MapPath(".")+"\\"+"test.xls","XLS","","",true,false,false,"","",true);
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlsheet1);
System.Runtime.InteropServices.Marshal.ReleaseComObject(objChartSpace);
xlsheet1=null;
}
catch (System.Exception e1)
{
Response.Write(e1.Message);
}
}
private void addPictureToExcelSheet(OWC10.ChartSpace objChartSpace,Excel.Worksheet objSheet )
{
try
{
string strPicFileName;
Excel.Shape objPicture;
int sizeX = 800;
int sizeY = 600;
strPicFileName = Server.MapPath(".") + "\\flag_uk.gif";
objChartSpace.ExportPicture(strPicFileName, "gif", sizeX, sizeY);
objPicture = objSheet.Shapes.AddPicture(strPicFileName, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 0, 0, sizeX, sizeY);
}
catch (System.Exception e)
{
Response.Write (e.Message);
}
}
I have also made my application to run as a single threaded application. (using ASPCompat = "true").
I get Exceptions & error messages.
Could anyone provide a better solution to my problem. OR tell me if I am missing something here.
Thanks in advance,
Vidya

I want to control the number of instances of my application and if this number is greater than a fixed number, give the focus to one of the opened instances.
Any suggestion??

hi, I am using following code to invoke my DLL and it's functions.
Assembly assemScenarioPreview = Assembly.LoadFrom(Some Path);
Type typeScenarioPreview = assemScenarioPreview.GetType(...);
Object obj = Activator.CreateInstance(typeScenarioPreview);
MethodInfo methodofScenarioPreview = typeScenarioPreview.GetMethod("Run");
methodofScenarioPreview.Invoke(obj, null);
methodofScenarioPreview = typeScenarioPreview.GetMethod("CleanUp");
methodofScenarioPreview.Invoke(obj, null);
In first chance it's get executed. but next time it throws an Exception.
"Exception has been thrown by the target of an invocation"
If I closed the client then then again ran the same code. it works..
What is the possible problem ..

Generally, a try/catch block around this will let you see what the exeption says about itself. Very useful stuff. Do something like the following, and you'll get information about the exception. (Also, be aware that the InnerException memeber may need to be looked at in some rarer occasions.)
try
{
// Your code here.
}
catch (Exception err)
{
System.Diagnostics.Trace.WriteLine(err.ToString());
// or
MessageBox.Show(err.ToString());
}

Please help me if you know the answer to this. I want to create a dataAdapter, that fills a dataSet. However, I have a stored procedure that I want to use, that takes one int as input. I have been trying this for a few hours now, and have come no closer.

Design time:
You have to set your parameter to the Parameters collection of the Command object.
Run time:
Use the Add method of the Parameters collection to create a Parameter object for the parameter in the stored procedure.

So I'm doing something like :
[Category("Visual"),
DefaultValue(XXXX)
]
public Color MyColor { get{..} set{..} }
What should I put in XXX to get my color initialized correctly .. whatever I put in it, I get a wrong value or color !!
Cheers,
MrPink

Well,
[
...
DefaultValue(Color.Black),
]
Does not work 
|
|
|
|

What about:
[
...
DefaultValue(KnownColor.Black),
]

Memory Management
I am using mid form in a windows forms application. Every time I am loading new child windows memory is going up(it’s ok). When I close them memory is not coming down. I am disposing child windows as they close.
Why is this happening ?
What is the solution for this problem ?
What are the best practices for memory management.
Thanks

If you are using task manager to detect memory usage, what you are seeing is the programs working set and not the atuall memory usage.
You say you are using the Dispose method as you close windows. But do those child windows use any resources that are not automatically disposed?
Contrary to popular belief, .NET's automaticall memory management does not imply immediate 100% resource cleanup. Some resources have to be cleaned up manually to decrease memory footprint at any given time since the garbage collector funtions in a non-deterministic way.
