I'm programming in C# but I thought this would be a VB question
i'm not sure how to do this, but assume I've got a text box that has a properties.
The properties dynamically change throughout the program, upon request, is there a method through system way to get the text box (or any checkbox, radio button group, label etc.) to change back to its original state?
|
|
|
|
|
No. The controls do not keep a record of their initial state are application startup.
You have to write a method that will reset all the properties of a control to a state that you want. Call this method when you want to reset the textbox.
|

Hi,
alternatively you can hide the original Control, then call an "init" method, which
clones the Control, adds it to its parents.Controls and makes it visible.
When you want the original back, remove the Clone, and call "init" again.
So it is always a clone that is shown, gets modified, and the original is never touched.

Though I've never had to reset controls back to a known state, (I tend to destroy and create entire forms instead) that's a trick I'll have to put in the bag.

I made sure my bag of tricks is an ArrayList, so it accepts all kinds of objects,
and is only limited by total amount of memory available. 
Come to think of it, it more resembles a Heap, difficult to enumerate...

Yeah, same with mine. Well, not really a digital heap, but a huge pile of sticky notes.

I need to read 4 hexadecimal chars from a textbox and put them into a Uint
how can I do that?

I need to see if I can change the hex 2.
ie:
textbox2.text = "1212abab"
the uint returned must be 1212 and another abab.

Hi,
you could:
1. use long.TryParse() and then split the long in upper and lower halfs.
2. split the string in two parts, and use int.TryParse() on each of them.
The second method may be more difficult since it may have to cope with varying string lengths
when leading zeroes are omitted in the string.

You can use
uint num = Convert.ToUInt16(textBox1.Text, 16);
If the textbox contains more than 4 letters and if you want to change each 4 letters in to their uint value, you should first write a text splitter which is very simple with string.substring() function.

I have an application that i have deployed using winforms. I have many users using this application and it works for every1 except one person!!!! I cannot isolate the problem. She gets the following error:
EventType:clr20r3
P1: admin.exe
P2:1.0.0.0
P3:464caceb
P4:admin
P5:1.0.0.0
P6: 464caceb
P7:42
P8:4c
P9:system.nullreferenceexception
I want a line number or something that give me a damn hint on where the null exception is occuring. I received this info from the event viewer. HEELLPP!!!

After doing a quick search on google, and selected the top result, I got This result[^]. See if that helps you out.

What you can do is set an application level thread exception handler. This is the top level event exception handler that is capable of catching exceptions. Then, you can simply extract the stack trace of the error that caused this.

I have a gridview and a dataset. When I start my application I see the results in my gridview. When I clic on edit and chanche some value and click on update it wil give me this error:
ObjectDataSource 'ObjectDataSourcePersoon' could not find a non-generic method 'Update' that has parameters: naam, tussenvoegsel, achternaam, adres, woonplaats, telefoonnummer, original_id, Original_naam, Original_tussenvoegsel, Original_achternaam, Original_adres, Original_woonplaats, Original_telefoonnummer.
check here my dataset update method
Does someone know whats the problem??
|

Your objectdatasource needs to have a update method that has the parameters that you see in the error. IN that method you should run a sql statement that updates the sql database. You perhaps have put an update method in your objectdatasource definition, but it probably doesn't match the one defined in the error. NOTE the columns are auto generated based off the columns in the gridview.
Hope that helps.

Hello all. I have a datagridview (genericGrid) and a bindingsource (genericBS). genericGrid's datasource is genericBS. I want to programmatically switch genericBS's DataSource and Datamember. Then, display those values on the genericGrid.
What I've tried:
Using a switch statement to change genericBS's DataSource and DataMember properties on the load. Then, called genericBS.ResetBinding(true). This is supposed to force genericGrid to refresh its rows. Amazingly, it doesn't work.
What actually works:
I've resorted to creating a bindingsource for each table. Then using a switch statement to change genericGrid.DataSource. This works.
But, there has to be a way to use just one bindingsource, right? Any suggestions?

Got an enum. Got 2 get methods for it. One returns the instance of the enum itself, one intends to return the int used in the enum.
public enum elementTypes
{
normalText = 0,
hidden = 1,
programData = 2,
}
There are more but this is an idea.
As I said I'd like to be able to get the actual number, not the name or an instance.

The only way I know of doing this is:
elementTypes et;
//This will give you the number
(Int32)et.hidden;
Hope that helps.

Fantastic.
Out of lack of skills, what the heck does the (Int32) prefix do? Is it some sort of implicit conversion?

Right. It casts the Enum as a number. It is kind of silly, but it the only way I know of to get the enums numerical value. I am sure someone else will post a different way of doing it, but that is the way I normally do it.
