In your button/checkbox event handler, create a new instance of a System.Windows.Forms.TextBox and add it to your form's controls collection using the Controls.Add method.

Hi,
I have some Rich Text Control that i use as label ( im not using Static label because i need to change the color and font of some chars ) that i set to it in Run Time some String.
In case the string is too long ( the size of the Rich Text label is not auto size ( i mean that the size is const ) ) there will be some Tool Tip with the all string.
My question is ... how can i know if the string is too long ?
Is there is some way ?
Thanks for any help.

int stringlenght = rtb.Length;

This will bring back the string lengh of the all rich text ... and this is not what i need.

RTB.Text.Length would give the number of actual characters; that is good enough when
using a non-proportional font.
For proportional fonts, this may do it:
create a second but invisible RTB with AutoSize, give it the same text, read its Width,
compare with the Width you gave the original RTB and act accordingly.

In code behind, borderstyle property is set. I want to do the same using javascript.
TextBox.BorderStyle = BorderStyle.NotSet;
Can you suggest something using
document.getElementById('<%=TextBox.ClientID%>'...?
Please help.
Thanks

hi
I cant seem to add 24 hours onto a datetime variable.
i have a startTime value and with that i want to add 24 hours to it to get a endTime.
what i have right now is:
DateTime startTime = DateTime.Parse(Request.QueryString["LogonDate"]);<br />
<br />
DateTime endTime = startTime;<br />
<br />
endTime.AddHours(24);
startTime's value is for eg. "2007/06/01 12:00:00AM"
but its not adding 24hours to endTime variable. It stays the same as the startTime.
Please somebody help me..
|

try this instead:
DateTime startTime = DateTime.Parse(Request.QueryString["LogonDate"]);
DateTime endTime = startTime.AddHours(24);
Without checking the docs I strongly suspect AddHours returns a new DateTime instead of modifying the existing one.

Correct - DateTime is immutable.

Hi,
the DateTime methods return a new DateTime, they do not change an existing one,
hence you need endTime=endTime.AddHours(24);

As others have said, the methods on DateTime do not modify the object you have. That is because the DateTime object is immutable. That means that once it is created it cannot be changed, you have to create a new one.
Had you done the simplest of research - like read the documentation - you would have found this out. (Hint: In pretty much all windows applications pressing F1 will bring up the documentation.)

Perhaps his F1 key is immutable and mapped to 'Switch Weapons' or 'Strafe'. (Do games still have strafe, like the original Doom?)

i want to develop a simulation program that can be used to simulate the actual windows
i.e :: in the MCSE exams there is a part is called simulation questions, in these questions a window like the actual windows interface appears and you can interact with it, as if you are dealing with actual windows environment
if any one have any idea how can i design this,, i need help about this topic
many thanks

There may be some instances that I would load the dll library. One time that I might be using this abc.dll then later in time that I would have the application to change to different dll which would be xyz.dll. Basically that they have the methods but have very different algorithms inside there.
What's the best way for me to do that? Right now that I'm using this:
<br />
Assembly a = Assembly.LoadFrom("abc.dll");<br />
Type mm = a.GetType("abc");<br />
object o = Activator.CreateInstance(mm);<br />
object[] par = new object[] { };<br />
ds_LUT = (DataSet)(mm.InvokeMember("GetLutTable", BindingFlags.Default |<br />
BindingFlags.InvokeMethod, null, o, par));<br />
<br />
<br />
<br />
Is there a way to keep the dll open until I am "finished" with it so I can close it and open the other dll? That will be done during runtime.<br />
<br />
Additional note: The dll are in c# language and was created in Visual Studio.Net 2005 software.

Without getting into additional app domains, once the DLL is loaded you will not be able to unload it. You can load more than one DLL at a time, so the idea of needing to "close it and open the other dll" doesn't really apply.
|
|
|
|
|
The only way to do this would be to have the DLL loaded into a separate AppDomain, which you could then unload. Mind you, I don't see what benefit this would bring you, as the Type would be completely different when you load up the new DLL - even if they have the same name, they really are different types so you won't have to worry about implementation collisions.
