Hi, I have this database that contains 3 tables, and I want to bind its contents to textboxes. I'm able to bind them correctly (I see the values in the TextBoxes) but I can't update them when I select another row of a given table. I'll explain what I do.
I have a Next and a Previous button. When I push the Next, I do the following:
BindingManagerBase bm = BindingContext[networkDataSet.Tables["TableOne"]];
if(bm != null && bm.Position < bm.Count -1)
bm.Position++;
CurrencyManager cm = bm as CurrencyManager;
if(cm != null)
cm.Refresh();
The code executes, the Position increments, but doesn't update the TextBoxes with the values contained in the next Rows...
What do I do wrong?
Thanks!!!

Isn't this working ? string[] mine = (string[])myArray;

unfortunately it doesn't, I want to cast an object array returned by ToArray() (of a queue object) to a string array...

The Queue class is marked serializable, so all you should need is for the objects being managed by the queue to be serializable as well.

Something like this:
ArrayList foo=new ArrayList();
object[] foobar=new object[] {"a", "b", "c"};
foo.AddRange(foobar);
string[] foostr=(string[])foo.ToArray(typeof(string));

the problem is that the ToArray method of the Queue class doesn't take any arguments! and the cast doesn't work, I get System.InvalidCastException "Specified cast is not valid"

Right, since it's returning a object[].
So, try (edited!):
ArrayList foo=new ArrayList();
foo.AddRange(queue.ToArray());
string[] foostr=(string[])foo.ToArray(typeof(string));
(I forgot the cast in my previous example). The cast here is correct (assuming everything in the queue is a string).

Has anybody seen this exception before?
"You must implement a default accessor on system.collections.queue because it inherits from ICollection."
I got this exception while trying to XMLSerialze a Queue object, which is the inner exception message of the caught exception.

I use Visual Studio 2003. Is there really no Drop Down List Box control in the VS Toolbox or is there something I am not seeing. This seems like such a fundamental control. They didn't provide one?
I know there is the ListBox, but there is no drop-down option. Right?
Thanks,
Mark

It's called a ComboBox, and then set its DropDownStyle property accordingly.

I have a comma seperated string that I need to be seperated and put into a ArrayList. The string looks like the following:
,-75.91067,45.31986,75.91067 West,45.31986 North,Peter- IT Development,0404000045,{233423},SMTP,27/05/2005 5:20:00 PM,27/05/2005 5:20:07 PM,27/05/2005 17:20:07,Sensors.xml,Y,0,0,0,0,0,0,00000000,01000000,Previous: 0 Current: 0,Previous: 0 Current:1,Previous: 0 Current: 0,Good,0,Pending,Info,Info,,;,

Hi, folks --
I did a ton of searching today on Google and searched The Code Project's forums but haven't been able to find an answer to this question yet. (Too much noise from related topics, I think.) But I *know* I ran across something on this topic a month ago or so...
Anyways, I'm writing an app that allows you to create graphs. So I'd like to create a small thumbnail of the graph and apply it to the File so that when the user is in a folder in Thumbnails view, the user can see a that thumbnail.
Can someone point me to an article, blog, or other posting with info on this topic?
Many thanks!
Anthony

Hi,
See this code
Image.GetThumbnailImageAbort myCallback =
new Image.GetThumbnailImageAbort(ThumbnailCallback);
Image img =Image.FromFile("d:\\tests.bmp");
Image tmpImg=img.GetThumbnailImage(20,20,myCallback,IntPtr.Zero);
Image myThumbnail = img.GetThumbnailImage(
40, 40, myCallback, IntPtr.Zero);
Upto here it is working fine
this.CreateGraphics().DrawImage(myThumbnail, 150, 75);
It is not drawing see this

Just to clarify...
I'm not asking how to create a thumbnail of any given image. Fortunately, there are a ton of resources out there on that topic.
I'm asking how to apply a "preview thumbnail" to a file so that when the user is browsing through his harddrive, he'll be able to see it without opening the file.
For example, create a drawing in Visio and save the file.
Now open the folder which contains the saved Visio document. Change the view style for the folder from "Details" (or "List" or whatever) to "Thumbnails". Instead of seeing the Visio file type icon representing the document, you'll actually see a "preview thumbnail" of the first tab's drawing in the folder.
Cool!
So how can we achieve the same effect?
Thanks!
Anthony

I'm writing a nic configuation app. I want to same each of my profiles for each card in an XML file. I'm looking at a program already written called SwitchNetConfig. I'm not quite sure how he's writting out the profiles. Can anyone suggest and easy XML class for writting out profiles to and XML file. Will XMLTextReader and XMLTextWriter work for me?
Thanks

Thanks Marc,
I'll take a look at it. I'm new to C# so I may have questions. I am, however, finding C# to be a heck of a lot easier to work with than VC++.
Thanks again

Indeed. But there are times when I really miss C++. And sites like this[^] wouldn't need to exist if you could do everything with .NET that you can do with MFC or direct API calls.

I need help with the following problem:
In the constructor of my form I call Application.EnableVisualStyles() to enable the Windows XP visual styles in my form; however, when the Alignment property of a tab control is set to either Left or Right, the text on the tab still shows as horizontal; therefore, only part of the first character in the tab text is visible.
|

One of the known bugs in the Tab control. This can be fixed quite easily by inheriting from the tab control, then only override the functionality of drawing a tab that is left- or right-aligned.
