"Loading of the ImageList did not succeed" error - C# Discussion Boards

you can change the name of the function using two ways:
1. one right click on the button and thwen go to the button properties, there you can change the name of the functions that are relevant to the button.

2. go to the Form.Designer.resx and search for the function name. it's looks like:
button1.OnClick+=Bla Bla Bla (the name of the function);....:->

Actually, when double clicked by moust on the control in design mode, my cursor goes in funtion Button1_Load(...). But actually it should have to go in function Button1_Click(...).It is my problem.
Any body help me.

however u can also find a article on how to drag a text from listbox to textbox on this site.. try to use search facility Smile | :)

I am writing DragDrop functionality program and using DoDragDrop(...) method of control to fire OnDragDrop(...) method. Some times OnDragDrop is not getting invoked (but sometimes it is).

Any Ideas?

Thanks

Hi I wrote a windows application. One of my client is sometimes getting the error below. I tested many times, but I never can reproduce the error. Does anyone know about this error?
Thanks

Hi,

Googling your "Loading of the ImageList did not succeed" resulted in many hits, including http://forums.lhotka.net/forums/thread/8361.aspx[^]

Seems there is a problem getting a handle freed, so loading the same thing twice will
fail ?!

Yes i read this.
I thought i didn't make a twice call. But after debugging step-by-step on my code, i saw that i made absolutely this mistake. Guess why: To fix another bug. Smile | :)

I have to always keep in my mind: "When you fix a bug, you may introduce a new bug".
Thanks for your response Smile | :)

this error is because you dropped the images you imported to the imageList or maybe because you deleted them or changed their directory or because you deleted the resources file Sniff | :^)

DataGridTableStyle DGTS = new DataGridTableStyle();
DGTS.HeaderBackColor = Color.Red;
dataGrid1.TableStyles.Add(DGTS);

What am I missing to apply this style Confused | :confused:

Hi Muammar,

Your code work well here. Please use your code after the this.Controls.Add(dataGrid1) .

EX:

this.Controls.Add(dataGrid1);
DataGridTableStyle DGTS = new DataGridTableStyle(); DGTS.HeaderBackColor = Color.Red;
dataGrid1.TableStyles.Add(DGTS);

Thanks,

Gopal.S

Funny but I cant find it in the designer class.
Thanks anyways!

Hi,

I'm developing a user control that is composed by other controls.
I'd like to know if it's possible to acces this inner controls at desing time when I use them in my application. I mean, if my control has a Button, Can I access that button once I've put the control in my application Form?
I Know I can access by code but I want to access in the designer. For example I wanto to change the location of the button.

I think it isn't possible, I'm right?

Thanks.

You can position your controls in the designer! however the positioning property should be set accordingly!

You can position the controls of a user control in the designer for the user control. If you then put the user control on a form you can only positition the whole user control as one, and not any idividual buttons that happen to be on it.

Changing the modifiers of the inner controls from a default 'private' to 'public' may serve ur purpose.

That would be unwise. It would break encapsualation. The better approach would be to have a set of methods that control access to just the things you want something outside to be able to manipulate.

it's not possible u can do that through coding.. but it's not possible at design (atleast according to my knowledge)

Strange subject; this has nothing to do with inheritance. You don't inherit a class when you create an instance of it.

It might be possible to build something that might enable you to redesign elements in the control in the designer, by exposing the location of the control as a property, and write code to handle the changes at design time. If it's even possible, it's probably far more work that it's worth.

I would suggest that you create a property in the user control that decides the location of the button. Like a ButtonLocation property that takes an enum value that represents the location.

I want to have a textbox in which the user can enter only nos. In vb.net we can match the pattern by using the like operator followe by the preferences (e.keyChar Like "[0-9.]"). But how can i do it in C#
Plz give me a hint.

Best Regards,
M. J. Jaya Chitra

You can use a maskedtextbox, or use regex, or use char.IsDigit, etc, in a key pressed event handler.

e.KeyCar LIKE "[0-9.]" is doing a regex pattern match, which is wasteful compared to char.IsDigit, but with different syntax, it works fine in C#.

How about using RegularExpressionValidator control of C#?

That does something entirely different, a regular expression validator tells you if your input was formatted correctly. He wants the control to not allow invalid input.
