Check the function CompleteWord() in the file SyntaxHighlightingTextBox.cs - you need to press CTRL and SPACE whilst typing a word,
it works me - if does not work for you put a breakpoint on the WndProc(ref Message m) function
for the case Win32.WM_KEYDOWN: and see why it's not being shown
Note: I did convert this into a Visual Studio 2005 solution but I presume that this should still work in 2003?
Mark.

I am designing a Windows Application. In the Settings class of this Application the user has to set a Directory Path to a Software program. I created a browsing button With the "FolderBrowserDialog" and with "FolderBrowserDialog.SelectedPath" I show this selected path in a textbox.
Now this works, but the "FolderBrowserDialog.SelectedPath" is not remembered by the application when I restart it.
How can can I store this SelectedPath? ( I also need this path as a string variable in other Classes)

Sorry but your link gave me an internal blackout... I just started programming in Visual C# using the Visual Studio manual. Sofar everything was clear, but I got stucked in how to handle my application settings. In the manual I found in the ApplicationSettingsBase this example for saving settings:
<br />
private void Form1_FormClosing(object sender, FormClosingEventArgs e)<br />
{<br />
frmSettings1.FormText = this.Text + '.';<br />
frmSettings1.Save();<br />
so my questions are:
1. Are the ApplicationSettingsBase commands the way to store and reload application settings?
2. If yes: is this applicable to the problem/question in my first message?
3. where should i put this code?

Make sure you use the same instance of FolderBrowserDialog in order the remember the settings. (A member variable or something like that)

hi,..
im doing some task that convert vb.net code into c#.net code...so there having some method..like...
Public Function GetCallbackResult() As String Implements _
System.Web.UI.ICallbackEventHandler.GetCallbackResult
// code running..
........
End Function
..........................................................
Partial Class <myclass>
Inherits System.Web.UI.Page
Implements System.Web.UI.ICallbackEventHandler
..............................................................
Public Shared Function GetInfoByDate(ByVal Id As Integer,
ByVal ToDate As Date,
Optional ByVal MaxRows As Integer=0)As SqlDataReader
// code running..
........
End Function
are their any c# code definitions or any sample plz supply me.
thanks in advance....

In C#:
public GetCallbackResult()
{
}
Remember that the interface is defined at the top of the class
public class MyClass : System.Web.UI.ICallbackEventHandler
{
}
ASysSolvers wrote: Partial Class

ASysSolvers wrote: Public Shared Function GetInfoByDate(ByVal Id As Integer,

C# doesn't support optional parameters like VB does. You have to create overloaded methods like this:
public static SqlDataReader GetInfoByDate(int Id, DateTime ToDate)
{
GetInfoByDate(Id, ToDate, 0);
}
public static SqlDataReader (int Id, DateTime Date, int MaxRows)
{
}
Does this help?

I'm not 100% sure of this one, but I think it should be:
Public Function GetCallbackResult() As String Implements _
System.Web.UI.ICallbackEventHandler.GetCallbackResult
End Function
public override string GetCallbackResult() This is inheritance of both a base class and an interface, which uses the same syntax.
Partial Class
Inherits System.Web.UI.Page
Implements System.Web.UI.ICallbackEventHandler
partial class : System.Web.UI.Page, System.Web.UI.ICallbackEventHandler C# doesn't allow optional parameters. You achieve this by creating overloads on the function. In this case, the "shorter" function just calls the "longer" one and passes the parameters along with the default value for MaxRows.
Public Shared Function GetInfoByDate(ByVal Id As Integer,
ByVal ToDate As Date,
Optional ByVal MaxRows As Integer=0)As SqlDataReader
End Function
public static SqlDataReader GetInfoByDate(int id, Date toDate)
{
return GetInfoByDate(Id, ToDate, 0);
}
public static SqlDataReader GetInfoByDate(int id, Date toDate, int maxRows)Also, note the syntax difference. C# is a case-sensitive language, unlike VB.NET.

I have a scrollable pane with images in it.
I would like to move the contents of the pane from a function.
The only thing I have found so far is to call performScrollHorizontal several times.
Ideally I would like to call scrollable.panel.hPos = 4711 or somthing like that.
I tried using SetScrollPos but that only moved the scrollbar not the content.
Any tips to where I should start looking next?

Guys,
A few days ago I asked about an assignment we had to do here at work. convert "aabb" to "aAbB" and set it to the textbox as quickly as possible. I think the conversion itself is very quick, reading in and converting in 1 or 2 seconds, but setting the entire thing in the texbox takes me another 10 seconds! (20 MB file)
I've read about the AppendText property and tried to set my characterarray to the box inside my loop, but so far the fastest results I got where form txtbox_result.Text = new string(text); where text = char [].
Any ideas on how to speed this up? (Suspend/resumelayout don't help either)
thanks !
PS: here's tho code I got so far:
starttime = DateTime.Now;
reader = new System.IO.StreamReader(openfiledlg.FileName);
char [] text = reader.ReadToEnd().ToCharArray();
reader.Close();
difference = DateTime.Now - starttime;
lbl_result.Text = "File read: " + difference.TotalMilliseconds + " milliseconds.";
lbl_result.Refresh();
pb_conversion.Maximum = text.Length;
int i2 = 0;
for(int i = 1; i < text.Length; i+=2){
text[i] = char.ToUpper(text[i]);
if(++i2 == 1000){
i2 = 0;
pb_conversion.Value = i;
}
}
difference = DateTime.Now - starttime;
lbl_result.Text = "conversion: " + difference.TotalMilliseconds + " milliseconds.";
lbl_result.Refresh();
pb_conversion.Value = pb_conversion.Maximum;
txtbox_result.SuspendLayout();
txtbox_result.Text = new string(text);
txtbox_result.ResumeLayout();
difference = DateTime.Now - starttime;
lbl_result.Text = "Done in: " + difference.TotalMilliseconds + " milliseconds.";
V.
I found a living worth working for, but haven't found work worth living for.

Do you really need all this text in a textbox?
If you really do, I would consider loading a small portion of text first and then appending the rest in a separate thread.
|
|
|
|

lol, it's a test at work and one of the requirements was, show conversion in a textbox.
I don't think that this one will work because timing only counts when everything is done. Good idea though. tnx.

The textbox aren't really designed for holding 20MB of text.
Try opening the file in notepad and see how much time it take.
A RichTextBox might be a better choice in your case.

He he, don't tell me  .
the rich textbox does give a slight improvement .

I'm not too sure about putting text into a textbox quicker, but if you definately know that every 2nd character is a letter, then using
text[i] = (char)((int)text[i] - 32);
is quicker than using
text[i] = char.ToUpper(text[i]);
|
|
|
|
|
if(char.IsLetter(text[i])){
text[i] = (char)((int)text[i] - 32);
}
gained me 1 second thanks
(this is actually kinda fun  , I learned a lot here...  )

You could even call your progress bar update fewer times than you are, with a 20 meg file you're currently calling the progress bar update more than 20,000 times.
If this takes 10 secs to go through the for loop, that's 2000 progress bar updates per second, bit of overkill there.

Unfortunately this will only work for ANSI characters, so you're actually introducing a bug in order to gain a few ms...
Not a good deal IMHO.

It's not introducing a bug, if you had read the original thread from a few days ago you'd realise that this is what the OP wanted - 'convert "aabb" to "aAbB" and set it to the textbox as quickly as possible'.
Thanks.
