No need for sarcasm. The xml file has been copied to the same folder as the assembly when used in other projects. Intellisense works fine for methods and properties in the project that's using the xml-documented class lib, with the exception of overloaded indexers.

I need to time how long certain methods are taking to run to a very fine level. Too fine for using DateTime and TimeSpan. Does anyone know of any tools that i can use to analyse which methods are bottlenecks?
Thanks

Try a profiler like ANTS. Or use interop to query the performance counter.

I'm working on the same thing right now. System.Diagnostics provides access to the performance counters. That's all I can since I just looked at ten seconds ago.

It's exceedingly primitive, but combinations of System.Debug.Trace.WriteLines in conjunction with calls to System.Environment.TickCount have always served me well...just grab the tickcount into a long variable at the beginning of a method, and difference it with the current tickcount at the end of the method, then dump the output to the trace.

Ive downloaded this sample prg trying to get started with C# and directsound
http://www.c-sharpcorner.com/Code/2003/Jan/DotNetPiano.zip
Ive installed DX runtime 9.0 and SDK
I use MS V .NET 2003
I can see that .NET does not recognize the DX installation. It simply cannot reference the DX libraries.
How can I make this work?
|
|
|
|
|
The only way I got it to work was copying the DX9 assemblies out of the GAC and referencing from there. Of course, Windows Explorer doesn't allow copying out of the GAC; I had to use the command line to do it. :P

I have a combobox and I can't get it to display the selected value when i load my form :
I am manually populating the combobox rather than using comboBoxCFMName.DataBindings.Add
Saving works fine i.e. if I select a value from the combobox, everything will save back to the database but when the form is refreshed, the combobox doesn't display the value from the database. I have tried manually setting the combobox.SelectedValue, combobox.SelectedIndex and even combobox.Text (even a refresh), but none of them affect the value displayed in the combobox - it still displays the first value in its datasource. I have pasted the code below ...
/*-----------------------------------------------------------------------------------------------*/
dataViewRE.Table = DataSet.RE;
comboBoxName.DataSource = DataSet.CFM;
comboBoxName.DisplayMember = "Name";
comboBoxName.ValueMember = "ID";
if (dataViewRE.Count > 0)
{
comboBoxName.SelectedValue = dataViewRE[0].Row["ref_Name"].ToString();
// actual text that will be visible to the user of the combobox
string refName = DataSet.CFM.Select("ID = '" + dataViewRE[0].Row["ref_Name"].ToString() + "'")[0].ItemArray[1].ToString();
// index of the location at which the displayed text is stored in the combobox list
comboBoxName.SelectedIndex = comboBoxName.FindStringExact(refName);
// set the text of the combobox to the string to be displayed
comboBoxName.Text = refName;
comboBoxName.Refresh();
}
/*-----------------------------------------------------------------------------------------------*/
Any help appreciated ...
Thanks

I had a similar issue with the DropDownList and was able to set the SelectedIndex in the PreRender for the control.
I hope this helps.

Hello,
lets assume i have a filled ArrayList and want to print the content on a printer. How do i do this ?
Thank you for your assistance
Regards,
Peter

It depends on what you filled the ArrayList with. Do you want to print Strings?
//get printer settings
PrintDialog dlg = new PrintDialog();
dlg.Document = new PrintDocument();
dlg.Document.PrintPage += new PrintPageEventHandler( YourPrintMethod );
if(dlg.ShowDialog() == DialogResult.OK){
//start printing
dlg.Document.Print();
}
private void YourPrintMethod(object sender, PrintPageEventArgs e){
//loop through the array and print the objects
foreach(object obj in yourList){
e.Graphics.DrawString(...); //draw the object
}
}

Hello Corinna,
thank you for your help. Yes, i want print strings.
What do you mean with the three dots in
e.Graphics.DrawString(...); ???
Regards,
Peter

Graphics.DrawString is overloaded, there can be different parameter lists.
This is the easiest one:
SolidBrush brush = new SolidBrush(Color.black);
int verticalPosition = 0;
foreach(String s in yourList){
verticalPosition += this.Font.Height + 5;
e.Graphics.DrawString(s, this.Font, brush, 10, verticalPosition);
}

Hi Corinna,
thank you very much, this works fine.

Peter

i am a C++ coder who recently made the conversion to C# (with which i am very pleased)
and yes i get it the list and and array list and all of that stuff is under System.Collections but i want to know if there is anway to make them return anything other than object
for instance if i have a multi level vector... er arraylist how can i make it so that i can say:
fu[i].bar[j].symbol = 6;
ok its not a real example but it is something that i would like to be able to do
i played with the get type function since it will return something's original type (before casting to say object) but it requiers a ';' after it so that didn't work (example of what i hoped would work ...
get {return (array_name[index].getType())[index];}
...)
but anyway if anyone has ideas feel free to share
Hope is denial of reality

Just create a new collection class inherited from CollectionBase, and set its method data types to the data type you want.

Hmm... I don't quite understand what you're trying to do here... are you wanting to be able to access the object through its own type rather than through the object type? If so, then the method above will work well for this.

Hmm... that should be GetType() not getType() . Other than that, it should work, except what's that extra ')' for?

Is there a way to put one line of code into two lines. Say for instance I had a huge line of code and it goes way off the right of the page, is there syntax so that I could make it go to the next line.

Yes, try Enter
static
void
Main
()
{
System
.
Console
.
WriteLine
(
"hello"

" "
+
"world"
)
;
}

It's that easy eh,just wasn't sure. Thanks!

Well, in C# the end of the statement is signaled with a semicolon, so you should be able to span a statement across multiple lines. Can you show an example of a huge line?

I wrote a class that i can essential use any where for any of my Inet enabled applications. It serialize's/compresses/encrypts objects and sends them over a net work were it will rebuild it and return the object. it works great but my problem is, i am writing a Chat/File sharing application..it works fine...but i love to criticize my own code and think of how i can make it more efficient, but my lack of experience in developing internet applications and data packets to send is really leaving me stumped. Could anyone help me and point me in the write direction ? i want the system to be as Secure as possible despite the fact that the objects are already encrypt. Anyways thanks for baring with me here...
