thanks for speedy reply Christian, but that will just scroll to end of line left or right, i wanted to scroll char at a time either way.
i got it sorted anyway, in all my attempts i inadvertantly set scrollbars to none on the textbox, so its working now
however, i have reduced the size of the textbox so you cannot see the scrollbar and am using custom buttons at either end depending on which side is overflowed.
the question,
can i completely hide the scrollbar, because there is still a 2 pixel scrollbar under the textbox, and my form colour really makes it standout ?
kind regards,
g00fy

I doubt you can hide it. I think a variation on the code I showed you is the way to go, you can scroll to where-ever you like, by selecting it first.

I have the following code:
this.providersAdapter = new SqlDataAdapter("SELECT * FROM Providers", this.dbCon);
this.providersTable = new DataTable();
providersAdapter.Fill(this.providersTable);
When I run this code, an exception occurs on the line marked above, it says
An unhandled exception of type System.Data.SqlCliend.SqlException occured in System.data.dll
Additional Information: System error.
it's driving me crazy, any information is highly appreciated...

Hi all,
How can I create a custom component that can be
drawn from the toolbox in vs studio which can be visualized
in the design form ? When I extend an windows forms control, but it
can't be shown on the design form in the vs studio .net ?
Thanks

You might need to create some design for that or can extend existing design class. To do this you need to provide some attribute values.
hope this helps

Following is the code I am using...
<br />
protected override void DoDiscoverParameters(char parameterToken)<br />
{<br />
this.parameterToken = parameterToken;<br />
using (IfxCommand newCommand = CreateNewCommandAndConnectionForDiscovery())<br />
{<br />
IfxCommandBuilder.DeriveParameters(newCommand);<br />
<br />
foreach (IDataParameter parameter in newCommand.Parameters)<br />
{<br />
IDataParameter cloneParameter = (IDataParameter)((ICloneable)parameter).Clone();<br />
cloneParameter.ParameterName = BuildParameterName(cloneParameter.ParameterName);<br />
this.command.Parameters.Add(cloneParameter);<br />
}<br />
newCommand.Connection.Close();<br />
}<br />
}
There I get the error saying "Specified cast is not valid." only for informix. I am creating Enterprise Library for Informix using IBM .NET informix libraries.
Please help.

Hello
I have a javascript that hides controls on a page depending on a few settings. At the moment I only call this script from the Page's Body_OnLoad event. The problem is I have a ASP:Button with autopostback = true, and when this is pushed all the controls that were hidden by the javascript suddenly appears. Where do I call the javascript to run it after every server request?
/Regards Magnus

Why can't you set the visible property on the server ? Otherwise, use RegisterClientScriptBlock to put the code in there every time.

thanks alot!
Actually I could use the .visible on server, but its quite alot to hide, and I already have the javscript ready so I'd prefer to call that. Also, I was interested in how one would go about doing it the other way
edit: and I also get "object required" if I hide with .visible on server and after that fire up the javascript.

Hi,
I'm trying to use the enter key on the pocket pc keyboard. Is there anyway that I can click on the enter key on the pocket pc keyboard to execute anything?
|
|
|
|
|
put this in you constructor code:
this.Enter += new System.EventHandler(this.MainForm_Enter);
And this to handle the event:
private void MainForm_Enter(object sender, System.EventArgs e)
{
//put any code here to handle the enter key
}
Cheers.

Hi
i have code like this:
else if (dane[0]==komunikat.PLPobierzRekord)<br />
{<br />
BinaryFormatter bf = new BinaryFormatter();<br />
MemoryStream ms=new MemoryStream();<br />
bf.Serialize(ms,Poldane[0]);<br />
byte[] buffer = ms.ToArray();<br />
<br />
System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();<br />
byte[] bajt=encoding.GetBytes(komunikat.PLZwrocRekord);<br />
byte[] dana=new byte[bajt.Length+buffer.Length];<br />
for (int a=0;a<buffer.Length;a++)<br />
{<br />
•1 dana[a+bajt.Length+1]=buffer[a];<br />
}<br />
for (int a=0;a<bajt.Length;a++)<br />
{<br />
•2 dana[a]=bajt[a];<br />
}<br />
<br />
dana[bajt.Length]=149;<br />
<br />
•3 MessageBox.Show(this,"a");<br />
}<br />
where
•1, •2, •3 - breakpoint
And here is a surprise... breakpoint 1 and 2 work and visual studio stop on this point but never stop obn breakpoint number 3. Why?? When i trace program step by step last step is before breakpoint 3 and program leave this else if block?!

Hi,
i rebuid all... and nothing change... but i found an error i code... i try set element in array bigger then declared array... but i don't know why program don't return error?!
Greetings

Maybe you were writing onto the null terminator ?
Anyhow, if the breakpoint is not stopped, and the code is not called, then you're not running the code you're building, one way or the other. I don't know why.

Hi!
I guess the line before the breakpoint throws an exception that's not being caught.
This could be the reason why the breakpoint is never reached.

Hi,
it's weird but, i run program in VS in debug mode... any line don't throw exception... when i going step by step program move out from block without throwing exception and do not reach next line?!
Greetings

Try encapsulating the line in question in a try/catch block to verify if this is really the reason for the problems you're facing.
Sometimes excaptions get through unnoticed if they are not occurring in the UI thread. In this case the one thread just dies, but the rest of the program continues to run.

Hi,
it is it... when i encapsulate the line in try/catch block then i can see exception...
thx

Did you add the MessageBox.Show line later? My guess is there is a mismatch between the PDB file and your executable. Try cleaning and rebuilding the solution, that should solve your problem.
