ps.ShowDialog();

}

}

int n = 0;

m:
if (ValidatePassword())

else
{

n++;
while (n<4)
{
MessageBox.Show("Erorr");

goto m;

I've hit a stumbling block on trying to figure out this problem. I have a winform app written in C# that was started back with 1.0 frame, then upgraded to 1.1, and recently I created a test 3.5 version. The deployed app is still the 1.1 as we have a lot of old 98 machines several of which don't want to upgrade to the 2.0 framework.

Here's the simplified code that I'm having problems with:

//1
PrintDocument printDocument1=new PrintDocument();
printDocument1.PrinterSettings.PrinterName=LastPrinterName;
//2
PrinterSettings ps=printDocument1.PrinterSettings;
PageSettings dps=ps.DefaultPageSettings;
string defaultsourcename=dps.PaperSource.SourceName;
//3
foreach(PaperSource p in ps.PaperSources)
comboBoxPaperSources.Items.Add(p.SourceName);
//4
string defaultsizename=dps.PaperSize.PaperName;
//5
foreach(PaperSize p in ps.PaperSizes)
comboBoxPaperSizes.Items.Add(p.PaperName);
//6

Basically my software has some 280 different reports and different ones go to different printers and to different sizes of paper. So the full code brings up an option screen that remembers the last settings and allows the user to store the settings for the specific report section and select a checkbox to not ask them for settings the next time they generate the report. The comments with numbers are to help identify how long it takes to do each section.

On my machine, a dual-core Server 2008 64 bit 4 gigs of ram, 8 printers set up, my 3.5 version in release mode takes this long:
1->2 0ms
1->3 31.2ms
1->4 46.8ms
1->5 78ms
1->6 109.2ms
On another Vista 32 bit machine, 2 gigs of ram, 12 printers set up, my 1.1 version in debug mode:
1->2 0ms
1->3 73ms
1->4 101ms
1->5 201ms
1->6 289ms
On my machine in a Hyper-V XP 32 bit window, 7 printers set up, using my 1.1 version in debug mode:
1->2 0ms
1->3 78.08ms
1->4 93.7ms
1->5 171.79ms
1->6 234.26ms
On my bosses new machine he received last week, a quad-core Vista 32 bit, 3 gigs of ram, 2 printers set up, my 3.5 version in release mode:
1->2 0ms
1->3 4,056ms
1->4 6,864ms
1->5 11,856ms
1->6 15,600ms
Using the 1.1 debug version puts 1->6 up to 17,255ms

Obviously, there's some sort of titanic problem with my bosses machine. The machine itself is incredibly fast. Every other operation in my software beats the tar timing-wise compared to my machine. As soon as it touches printers, it craps out. Wordpad/notepad/word/excel/acrobat/etc all seem to pull up printers fine. The machine is pretty "clean", all the crapware was uninstalled off of it, no virus scanner running, I've task manager killed everything non-critical. I've deleted all his printers out, reinstalled just the Microsoft XPS Document Writer. I've cleared out his temp folders and run a chkdsk. I've eliminated all the standard "this is why its slow" reasons that I know of. If it had been any other program on the machine, I would think its a windows issue, but since its just my software I'm stuck.

Does anyone have any suggestions on where to go from here?

It doesn't seem to be Vista 32 bit.
It doesn't seem to be number of printers.
It doesn't seem to be amount of ram.
It doesn't seem to be something running in the background.
It doesn't seem to be disk or printer corruption
It not affecting any "mainstream" apps
It doesn't seem to be a specific .NET framework version

So I don't know if its
Quad core and .NET
Some chunk of code I'm missing
Something I haven't thought of.

Hi,

my guess is the slow machine has one or more printers set up that are hard to find, networked ones e.g.
so it takes a long time building the list of available printers or whatever other information it needs
to respond to your code. So check the list of installed printers. Or (temporarily) remove most of them.

Smile | :)

Already tried that. I went down to having nothing but a local "virtual" printer(the XPS document writer that comes with Vista). Didn't change the speed very much.

Skip readonly columns in DataGridView

I have a DataGridView on a form with a number of columns that are calculated and hence set to readonly. What I wanted was to have these columns skipped whenever the user entered them. I thought to use the OnEnter event to test the readonly attribute of the current cell and set the currentcell to the next one. A problem arose using this methed in that by changing the currentcell in the event handler, I was invoking the non-reentrant changedcell method. Instead I resorted to a SendKeys.Send("{tab}") instead and this appears to work.

I had this same issue a while back. I did some searching and posted on forums and the SendKeys.Send("{Tab}") solution was the only one I was able to find. Let me know if you find something better.

This is the error which I am getting in this line-->dgDataItemgrp.DataMember = "myTable.RelLicData";

dsetView = dset.DefaultViewManager;
dgDataItemgrp.DataSource = dsetView ;
dgDataItemgrp.DataMember = "myTable.RelLicData";
DataRelation relLicData;
DataColumn colMaster1 = new DataColumn();
DataColumn colDetail1 = new DataColumn();

colMaster1 = this.dset.Tables["myTable"].Columns["LicensegroupID"];
colDetail1 = this.dset.Tables["myTable1"].Columns["LicensegroupID"];
relLicData = new DataRelation("RelLicData", colMaster1, colDetail1);
dset.Relations.Add(relLicData);

any clue what can be the reason ?

Really? I guess you need to clarify what you mean by "Doclet".

http://java.sun.com/j2se/1.4.2/docs/tooldocs/javadoc/overview.html[^]
Doclets are programs written in the Java^TM programming language that use the doclet API to specify the content and format of the output of the Javadoc tool.

no that's not the DOCKlet in mean, what i am talking about is a windows application that look like the system tray that has shortcuts to your favorite apps like the one in the MAC OS.
i didnt mean the java doclet.

So are you saying you just made that up? Don't do that, don't make up your own terminology. No one will have freakin clue what you are talking about. Can you doclet that?

I have no idea what the thing in the MAC OS is that you mentioned but what would OpenGL have to do with displaying shortcuts in a system tray? Confused | :confused:

And finally, this is the "Windows Forms" forum. That means System.Windows.Forms which is a namespace in the .NET Base Class Library. For questions working with Native Windows development you want to use the Visual C++/MFC forum. But be warned, if you don't use standard Windows programming terms it is unlikely anyone will figure out what you are talking about.
