Does the loop run at least once?
I suspect it is connector problem. You coud try using MySql Connector/Net(I Used it, because other connectors were painfull to get them working). It is a form of external dll that you can reference to it. And you are not required to install it as it is required with ODBC connector.
Try asking in their forum, you coud stumble upon a bug.

"Does the loop run at least once?" - no
Ok, thx

I say that you are to use.
for (int i = 0; i <= integer-1; i++)
or
for (int i = 0; i < integer; i++)
If reader.FieldCount = 4 get the i parts 0,1,2,3

Hi,
I am using c#.net and Microsoft.Office.Interop.Word dll to read the ms word document content. My requirement is to read all available bookmarks from the document.
I am able to read the number of bookmarks(count only) but failed to read the bookmark names.
Here is the code for reading bookmark count.
_Application wdApp = new Microsoft.Office.Interop.Word.Application();
_Document Doc = new Microsoft.Office.Interop.Word.Document();
Microsoft.Office.Interop.Word.Range wdRange;
object optional = System.Reflection.Missing.Value;
Doc = wdApp.Documents.Open(ref _fileName, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional, ref optional);
int intParaCount;
intParaCount = Doc.Bookmarks.Count;
Please provide the code for reading the available bookmark names from the word document.
Thanks in advance.
Veerendra

try
doc.Bookmarks.get_Item(index).name;

Hi,
I am using .NET to query indexing server (search engine for our Intranet)
If the user searches for "the,he,she,in" or "a" etc they will get an error page stating - "(The query contained only ignored words.)"
What is the best way to catch this and deliver something meaningful back to the page.
|
|
|
|
|
 It looks as you have problems with SQL Server Full-Text Search.
If I'm right you should post your question into General Database forum.

Wow. Let me spell it out for you.
1 - posting your email, which will get you spam from people who have nothing to do with this site, and almost certainly nothing else
2 - this is NOT the ASP.NET forum
3 - we are NOT here to tell you how to use google.
4 - it is INCREDIBLY rude to delete your message, no matter how stupid. It just clutters the forums.
The only way to write a chat app is with AJAX. ASP.NET has next to nothing to do with it. I suggest buying an AJAX book and reading it before coming back and using the correct forum to ask specific questions.

You've done just about everything wrong here. Try reading the guide on how to ask questions, do some research, and try using the right forum when you have a question that is more specific than 'do my work for me'.

Hello,
I wan to able to change the label when i select a radiobutton.
For example when i select the Yes radiobutton, it will show the text as Y and not Yes.
Is there a way to do that?
|
|
|
|
|
Yes. What control do you want to change the text on when the RadioButton is selected?
|
|
|
|
|
click, thanks for the reply.
|
|
|
|
|
"click" is an event. Do you want to change the text on the RadioButton, or a Label, or what?
Anyway, just wire the event "click" event to the control, then inside it: radioButton1.Text = "my new text"; or labelText1.Text = "my new text"; etc.
|
|
|
|
|
For example:
private void radioButton1_Click(object sender, EventArgs e)
{
radioButton1.Text = "my new text";
}
but to wire the event:
this.radioButton1.Click += new System.EventHandler(this.radioButton1_Click);
which is done automatically by the designer, but if you don't have VS, just add the above to your form's constructor with a change to the radio button control's name of course that matches the method signature (e.g. "radioButton1_Click" in this case).
