They obviously do not come from thin air. You can store them in a file, in a database ( but if you don't already have one, that seems like a waste of time ), or in the registry. I'd store them in an XML file.

If you know both of those things, then you already know how to retrieve them the second, or any, time the form is opened. simply do it in the Load event handler of the Form in question.

I don't understand your question then. You know how to use a database, but you don't get that if you want to store the values in your textboxes, you need to write code to store them, and to retrieve the values ?

you have 2 choices
either store the data locally as CG suggested or use form.hide(), this will require you to manage the open form differently but the form values will not change between open/hide events.

when a PDF file is opened in IE, I have to save that PDF without asking the user to save.
How to do this in c#?
Normally I am able to save the HTML pages opened in IE, but PDFs are not saved.
Is there any way to save the currently opened PDF without asking user to save?
|
|
|
|
|
No, there is no way. Because, it's acrobat, and not IE, that is showing the file, it's acrobat you'd need to interact with.

Then i suggest try using printer driver to PDF. If you select print, and then those drivers will save as PDF

You coud write code to automatcly print to PDF through driver

Ah - you just posted the wrong URL. not a good sign.
It probably means you're hitting F5, but you're trying to debug a release build and no debug build is present.
Or the build failed for some other reason. What does the output window say ?

Looks like there's a library you need to register. That will be a COM dll you are missing.
If you want to learn C#, don't download code and try to compile it at random, buy a book and work through it.

Dear All,
i have following code to run 34 activities at same time, but it seems it doesent.
foreach(ListViewItem prv in des.lProvinces.CheckedItems)
{
if (prv.Text.Equals("All"))
continue;
pmuAccessPath=string.Format("{0}\\{1}\\NSPDatabase.mdb",des.DestinationFolder,prv.Text.Trim());
if (!Directory.Exists(Path.GetDirectoryName(pmuAccessPath)))
Directory.CreateDirectory(Path.GetDirectoryName(pmuAccessPath));
if (!File.Exists(pmuAccessPath))
File.Copy(des.SourceAccessPath,pmuAccessPath);
Finish fin=new Finish();
pnlControls.Controls.Add(fin);
fin.Dock=DockStyle.Top;
fin.lblProvince.Text=string.Format("Province : ({0})",prv.Text);
fin.lblProvince.Refresh();
Triplet triplet=new Triplet(fin,pmuAccessPath,prv.Tag);
ThreadPool.QueueUserWorkItem(new WaitCallback(runMultiple),(object)triplet);
Thread.Sleep(50);}
the method runMultiple, queries some tables from sql server 2005 and then inserts those into Access Database.
count of items is 34, for the first time it performs all but then it stops and executes only one by one.
like one gets finished and another starts.
i want to all should run at same time?

ThreadPool is optimized and it will not start 34 threads to do the job even if there are 34 items in the queue. If you want all 34 to be executing, create your own thread and execute on it rather than using ThreadPool. But huge number of threads will make problems.

Why do you want to sleep here?

thanks for reply.
for sure haveing lots of threads are not adviseable, but in my case its only one time job.
so You mean i should use
I used following but didnt help
Thread t=new Thread(new ParameterizedThreadStart(runMultiple));
t.IsBackground=true;
t.Start((object)triplet);

Yes. Putting that inside the loop will start one thread on every iteration.
Abdul Rahman Hamidy wrote: but didnt help
How are you checking that it is not working?
|
|
|
|

well, Finish is a control which have progress bar and lables which gets updated on every transaction.
only one progress bar goes others are stop and does nothing.
when the one is finished then another starts. this shows that others are not working.
and at the same if open the access file then records are not in tables.

Fix your code. Hard to say more because you didn't post it.

Bitmap b=new Bitmap(@"d:\s.jpg");
pictuerbox1.Imege=b;

problem is with this line of your code.
you are deleting image but picture box still using it,
that why you getting error.
1 solution - try to set picturebox image to null before deleting it.
OR create bitmap from stream, like
FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
PictrureBox.Image=Image.FromStream(fs);
fs.Close();
hope this would help
