When I hit F5(Debug-Active configuration) it opens property page with title - Disassembly showing native code in VS.NET IDE and pops up Nullreference exception unhandled...I have placed breakpoint in first line of Main() but its not stopping there, indicating "Breakpoints will not currently be not hit, No symbols have been loaded for this document."
Any help will greatly be appriciated.....
REgards,

I think I had this happen about a month ago. Try "Clean Solution" under the Build menu, then rebuild it.

Thanks Dave,
No luck with Clean Solution, still getting NullReferenceException popup...Disassembly property page at address "VSHostUtil.HostProc.GetEntryPointAptThreadState"
Can you jus give a little strain to your brain to recall what you did to overcome the problem.

|
|
|
|
Yes, Rebooted. Problem has yet not been resolved, anything else would you like me to try?
|
|
|
|

I had a problem with the symbols not being loaded correctly, not the NullReferenceException.

I always insert the Microsoft Web Component in my user controls section in the toolbox.
it's under COM components: Microsoft Web Browser.
Create an object and call the Navigate function and pass your URL as parameter...
good luck.
No hurries, no worries.

Hi
I have a win app using webservice it shows data;
because of low speed connection i have a bad visualization of application.
can any one help me on this problem;
The WinForms render as :
.
.
.
myForm.Populate();
myForm.Show();
.
.
.
|

If you hvae a slow connection, the only thing you can do is try and reduce the amount of data coming from the WebService. Only ship exactly what you need to render the form.
You might also try asynchronous calls to the WebService. This would allow you to start rendering parts of the form that don't need data, then update the parts that do when the data comes back from the WebService. This usually gives the illusion of faster response, if done correctly.

What about multi threading ?
|
|

That IS multithreading. When you make an asychnronous call, a thread is created out of the thread pool to make the call while the UI thread goes on it's merry way.

There are no native .NET telephony APIs. You can use PInvoke interop to call the TAPI API functions though. Have a look at this[^] as a starting point.

I am trying to set the grouping / sorting fields at run-time from
C#.NET against a Crystal Report.
I'm using the code as provided in the help files using syntax like :
FieldDefinition FieldDef = new FieldDefinition();
FieldDef = Report.Database.Tables[0].Fields["FieldName"];
Report.DataDefinition.Groups[0].ConditionField = FieldDef;
I have the appropriate 'using' set up (for
CrystalDecisions.CrystalReports.Engine.FieldDefinition.FieldDefinition()).
When I attempt to compile this code I am presented with a build error
suggesting that :
'CrystalDecisions.CrystalReports.Engine.FieldDefinition.FieldDefinition()'
is inaccessible due to its protection level'.
I've followed / copied the code sample as suggested within the help files.
Where have I gone wrong / what am I missing ?
Any pointers / help would be appreciated.
Thanks in advance.
Hadi.

Finally I found a solution to the ever irritating problem of bi-directional relations between objects that are saved in a database. Ok, the solution wasn't really obvious and rather complicated if you ask me:
queryBuilder.Append("SELECT Computers.Computernummer,");
queryBuilder.Append("Computers.X,Computers.Y,Computers.Geblokkeerd,");
queryBuilder.Append("Leerlingen.Leerlingnummer,Leerlingen.Naam,");
queryBuilder.Append("Leerlingen.Klas,Leerlingen.Foto,");
queryBuilder.Append("Leerlingen.Geblokkeerd as LeerlingGeblokkeerd");
queryBuilder.Append(" FROM Computers LEFT OUTER JOIN ");
queryBuilder.Append(" Leerlingen ON Computers.Leerlingnummer");
queryBuilder.Append(" = Leerlingen.Leerlingnummer");
while (reader.Read())
{
Computer computer = new Computer();
...
if (!reader.IsDBNull(4))
{
Leerling leerling = new Leerling();
...
computer.Leerling = leerling;
leerling.Computer = computer;
}
...
In short, what I do here, I select a computer and possibly with it a student. This only happens when the student has been logged on to the computer. Sounds simple, code looks complicated.. And it took me quite some time to figure it out.
Maybe this tip can be good for others which have the same problem.

Can anyone tell me what are the C#, ASP.NET coding standards followed in the industry ?
