What you're doing is not recommended, and, in fact, actively discouraged. Changing system-wide settings affects other applications that are running and also affects the layout of the desktop. Remember, Windows is a shared system, running multiple applications at once. You have to make sure you app works and plays nice with others. Changing system-wide settings so your app looks good, can make another app running at the same time look bad.

I know if you did that to my machine while I'm working in Maya at 1900x1440, I'd be heading straight for Add/Remove Programs and dumping your app.

In general, agreed. THe only time forcing a resolution should be allowed is in full screen mode, and then be sure to restore the settings when the user closes or alt-tabs out of your program.

faxing from C# via Send Fax Wizard

I want to initiate the sending of a fax from within a C# application. I want to specify the file I want to send and then launch the Send Fax Wizard allowing the user to type in the fax number, the To, etc... Does anyone know how to do this? I noticed that Send Fax Wizard does not allow for attaching files. I was able to send faxes bypassing the Send Fax Wizard all together, but that's not entirely what I need.

Many thanks.

Thanks, but that's not entirely what I need. I need to use the Send Fax windows client and prompt the user for fax number, location, etc, etc. Any ideas would be greately appreciated.

The link you've indicated has to do with sending a fax from a web page. All I want to do use COM-Object (faxcom.dll) to fax a PDF document. I want to "attach" the document to the object and fire up the Send Fax Wizard.

Changing all cursor types on a form

Hello everybody,

I want to change the cursors over all input controls (textboxes) on a form in a loop.
I tried something like:

foreach(TextBox tb in formclassname) // but instead of a class a var is expected
{
   tb.Cursor = Cursors.No;       // change cursor of textboxes
}

What's the right code to make the expected operation ?
Thank you in advance

Assuming you are trying to change the cursors from within the form that the textboxes are on, you can try something like this:

foreach (Control tmp in this.Controls)
	if (tmp is TextBox)
		tmp.Cursor = Cursors.Hand;

Or like this:

foreach (Control tmp in this.Controls)
	if (tmp.GetType().Name == "TextBox")
		tmp.Cursor = Cursors.Hand;

Regards,
Polis

Can you practice what you teach?

Extend NumericUpDown

yala15-Dec-05 1:43

15-Dec-05 1:43

I would like to use a NumericUpDown and add the unit (feet, ...) after the number.
This is made by extending the NumericUpDown class and overriding the UpdateEditText method like that:
protected override void UpdateEditText()
{
//Let the base component format the number according to the different properties
base.UpdateEditText();
//Add the unit
base.ChangingText = true;
base.Text = base.Text + " " + unit;
base.ChangingText = false;
}

But the problem is when a user change a part of the text in the textbox,
the ParseEditText method cannot parse a string like "2 feet",
and i cannot override this method like it is not virtual or abstract in the base class (Why did Microsoft do that?).

Please help me to find a solution.

Thanks in advance

i am using com dll in my project which fires up event

code in vb is like this
Option Explicit
Dim WithEvents p As CLAMXLib.ClamEngine
Dim mresult As ClamResult

Private Sub p_OnScanComplete(ByVal result As CLAMXLib.IClamResult)
Set mresult = result
End Sub

in c#

CLAMXLib.ClamEngine p;
ClamResult mResult;

//now how will i catch events

code of class where i have to catch up event
public class clamresults
{
CLAMXLib.ClamEngine p;
ClamResult mResult;
public clamresults()
{
//
// TODO: Add constructor logic here
//
p=new ClamEngineClass();
p.Database.Path="E:\\projects backup\\ankitclam backup\\Clamtest\\database\\";

}
public string loadDatabase(string command,string dirpath)
{

if(command=="SCAN")
{
mResult=scanfile(dirpath);
}
else if(command=="RAWSCAN")
{
mResult=scanBuffer(dirpath);
}
else if(command=="CONTSCAN")
{
mResult=scandir(dirpath);
}

return mResult.Summary;

}
public ClamResult scandir(string dirpath)
{
p.Settings.ScanSupport=ClamSupport.Scan_Standard;
mResult= p.ScanDirectory(dirpath,0,ClamBoolType.False ,ClamBoolType.True);
return mResult;

}
public ClamResult scanfile(string dirpath)
{
p.Settings.ScanSupport=ClamSupport.Scan_Standard;
mResult=p.ScanFile(dirpath,ClamBoolType.True);
return mResult;

}
public ClamResult scanBuffer(string dirpath)
{
mResult=p.ScanBuffer(dirpath,ClamBoolType.False);
return mResult;
}

}

now how and where i will catch up events which will be generated from com dll

Object pooling in C#

rana7414-Dec-05 23:07

14-Dec-05 23:07

We have a c# object being referred to by ASP.NET application.We want to implement an object pool for the C# component,with the number of intances being configurable.
Assuming that ASP.NET is servicing requests in 25 concurrent threads,we want the services to be processed by the instances from the pool.
Moreover ,the instances are initialized right at the beginning.How do we implement this object pooling?
We need this architecture as the c# object contains a handle to a COM component which has a very expensive initialization process.
A pointer to a reference article will be very helpful

Time out exception

Dear All,

Dear All,

I made a webservice, which takes more than 70 seconds to compute something. When I simply run the webservice it returns me the result. But when I access it through application(C# window), it raise TIMEOUT exception.

I also tried via increasing the timout value for sessionState element but not able to solve the problem.

Smile | :)

With Regards
Manoj

Change the timeout for the object that handles the webservice call. It's the timeout for the web request, not the session timeout.

Thats easily the worst advice ive read here! DONT use varchar to store a date!

Also, to THE OP - Timestamp is a special type of binary column, and is not used to store time as the name does imply. To store date and time just create a Date column, which will store a date and time perfectly.

Remember to use parameterized queries (for dates especially as the command will take care of inserting the date correctly)
