I googled that first one, and came up with that whole site. Its going to save me, and others, hours of wasting time.

Though, thanks.

Yes

str.Add("Hello");
str.Add("World");

MessageBox.Show(str[0] + " " + str[1]);

a generic list (e.g. List<int>) is like a stretchable array, it will grow and shrink as you add/remove items. And you can access its elements using an index, and you can iterate its elements with foreach.

it is all in the documentation!

BTW: if all your objects are in a ListView, then listView.Items is holding them all; so you can index and iterate that directly. (Not a good idea if you need a layered approach, where the ListView is just part of the view, not of the business logic).

Yes, you can use a generic list exactly like an array in your C# program. The compiler handles the translation chores for you Thumbs Up | :thumbsup:

Images are shrunken => i want to get them shrink-proof

Hello @ all

I have a problem with my generated PNG - Images.
It's a bit strange for me but may be someone now what i can do to solve this problem.

My windows service create on the fly PNG - Images and store them as binary in a database.
The stored images are displayed later with a crystal report in a windows app.

That works very fine since years and also with different pc's (most XP-OS), but there is a problem with a new PC (XP-OS) since a few days.

All images are displayed shrunken in the reports and it's not the whole report.... only the images. Text- and Report still proportional.

Could it be that something is missing at the new machine ?

Any ideas how this could be ?

Thanks a lot!

Word Interop: Unable to save text in a document

Hi
Got stuck here. Word document gets saved in the correct directory with the correct name but the typed text doesn't persist. Please help. (*I have tested that the text is actually typed in the active document).

private void SaveDoc()
{
Word.Application wdApp;
Word.Document wdDoc;
wdApp = new Word.Application();
wdDoc = wdApp.Documents.Add(ref missing, ref missing, ref missing, ref missing);

//type some text
wdApp.Selection.TypeText("Some Heading"));

//set rtf doc paragraph 1 style to normal
object wdParaStyleName = "Heading 1"
wdDoc.Paragraphs[1].set_Style(ref wdParaStyleName);

//save rtf doc
wdApp.ChangeFileOpenDirectory("C:\\test\\");
object wdFileName = "TestDoc.rtf"
object saveFmt = Word.WdSaveFormat.wdFormatRTF;
wdApp.ActiveDocument.SaveAs(ref wdFileName, ref saveFmt, ref falseO, ref missing, ref falseO, ref missing, ref trueO, ref falseO, ref falseO, ref trueO, ref falseO, ref missing, ref falseO, ref falseO, ref missing, ref falseO);

//Quit Word
object saveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
wdApp.Quit(ref saveChanges, ref missing, ref missing);
}

Using doc.save() prompts the save dialog which defeats the purpose of automation.

Thanks
GJ

Documentation: This example includes the wdDoNotSaveChanges argument of the Close method to close without saving changes or prompting the user.

Try using the SaveAs() method.

object saveChanges = Word.WdSaveOptions.wdDoNotSaveChanges; This saves without the inserted text.
SaveAs() also doesn't work for inserting text. Could i possibly catch the save as event for the word application.

Hi all,

I am trying to catch the delete event from an Outlook appointment item. I can
get it working using the "Item.BeforeDelete" event but if the appointment is
a recurrence and you delete one occurence from the recurrence the
event is'nt triggered. Does any one know a way around this ?

Many thanks in advance
Kind regards,

Help with BackgroundWoker

Hi
I've got a web service running on a BackgroundWorker which updates the weather in a specified time limit. I've also got a combobox listing a whole bunch of cities. Now the thing is, in the Do_work event of the backgroundworker I update the weather and let the thread sleep for a couple of minutes, and if the user selects a new city, the user has to wait the specified amount of time before it updates. How can I get the weather to update say every 10 minutes, but as soon as a new city is selected, don't wait 10 minutes, and instead update the weather as soon as a new city is selected.
Is there a way to restart the BackgroundWorker perhaps?
