    - updating window in multithreaded app okay im making a mesh viewer for my engine in c#. Now my engine runs in a window, parented to a window in my c# application. My engine runs in its own thread started by my c# application. When i've finished rendering i tell opengl to swap buffers, which would normally display the contents to window, however in my c# appliation it does not update the window. How ever, if i put a call to my engine's render function in the windows paint method, it will be displayed, but only when i resize the window. Any ideas how to get the window updated each frame in my seperate engine thread edit: okay i made some progress, i now open a thread which invalidates the window then sleeps for 20ms. This seems to work nicely. Is it the best way to go about it Tag: Windows Forms General Text Box Entry Finished Windows Forms

    - Determining when a bound business objects, or any of its children, have changed I have one main business object in an application, which is a container for various other business objects, themselves container other business objects. It is bound throughout various aspects of the user interface using a BindingSource and its Current property. The object can then be "processed" so to speak, any number of times. I would like to be able to tell if the object has changed in between successive processes. I have looked at these various options: 1. Since all my business objects implement INotifyPropertyChanged, I added a dirty flag in each object that gets set when a property changes. The problem is I have no way for this to be reflected to the parent object, and eventually my main object. 2. Event handlers for BindingSource::CurrentItemChanged. However this only detects changes based on the CurrentChanged event or when properties of the CurrentItem change, so it won't detect changes to child objects. 3. CurrencyManager::ItemChanged event. Get the CurrencyManager via the BindingContext for my BindingSource and attach handlers for the ItemChanged event. Again it seems to only detect changes to the parent object and not children.

    - how to trigger BindingCompleteState.DataError Thanks for the reply! However, this reads for me somehow like "... occurs when there is Christmas in July". How can I set up a binding to a datasource (object datasource, if possible by any means) so that setting the property in the model works, but a validation error is reported I mean - Parse can fail only with an exception, the same holds for a TypeConverter, and if I set Cancel=true in the Validating event BindingComplete isn't even called. Let's have for example a Person object with a property "Age" of type int. How could I bind a text box to Person.Age so that I get BindingCompleteState.DataError whenever I enter a negative integer into the text box There is no problem pushing a negative integer into the Age property, but I don't see where I could implement a validation so that a DataError would be reported.

    - Coloring TabControl. nahguam wrote: TabControl inherits from Control so the properties BackColor and ForeColor *are* present. They have just been hidden from the VS designer. If you manually assign them (don't believe what intellisense tells you! :) ) It will compile. Unfortunately, modifying them seems to have no effect on the painting of the control. I'm not sure how you can overcome this problem directly. I would design my own UserControl to mimic the TabControl that you *can* choose the colours for. Thank you very much. I am wondering if you've done it yourselves, though, I just did after I read your post and this is what happened: it did compile all right but when I looked back at the code in the constructor the statement tabControl1.BackColor = was gone. Alas. A catch22. Tag: Windows Forms General Text Box Entry Finished Windows Forms

    - BindingNavigator disappears from Container UserControl at Design Time Hi, I have made a Container UserControl (with "ParentControlDesigner" attribute "trick") with a BindingNavigator inside it (when the UserControl is dropped over a form, the BindingNavigator appears semi-transparent). When I put that usercontrol on a form and drop some controls inside it, it shows properly. After the first run, the BindingNavigator control disappears from the UserControl at Design Time. Only the dropped controls are shown. The BindingNavigator reappears if I close de form designer e reopen it. Anyone have any idea how to solve this problem I'm using Visual Studo 2005 with C# Thank you Tag: Windows Forms General Text Box Entry Finished Windows Forms

    - How to avoid loops with handlers? Thx for your reply. However, I don't get it to work. This may not have anything to do with your example, but there's some more happening on the form. On of the things is that all my comboboxes are self made controls because of some bug with comboxes (when choosing from a list and making a selection empty and then switching focus to another control sets the Text property on empty but leaves the selectedindex intact.), so I made some Leave events as well and some logic to make forms "Dirty". All these events work perfect except in the case I just descripted in my original topic. Is there some more elegant solution to disable handlers or cancel them Tag: Windows Forms General Text Box Entry Finished Windows Forms

    - DataGridView - Column/Cell Not Selectable Hi, Thanks for your reply - but it didn't answer my question. I can easily make sure that only some columns are editable, but I want to make some columns not selectable. So if a user tries to click, tab, scroll, etc to a particular column it won't let them. Basically - I have a grid and want to have only one column selectable so can enter marks for that column, but have some other columns visible for infomation only. Kind Regards, Grant.

    - Memory Leak using FlowLayoutPanel? I have a problem with a possible memory leak in my WinForms app. I finally was able to figure this out and reproduce by doing the floowing. Add a FlowLayoutPanel to a form and have a process that adds (multiple) Buttons at runtime. Then i have a method that is called from an event (button click) that removes the controls like this: Code Snippet Me.FlowLayoutPanel1.Controls.Clear() then call the method to re-add them back using: Code Snippet Me.FlowLayoutPanel1.Controls.Add(New Button...) This works except for the Mem Usage on the machine. This goes thru the roof after loading 30 controls over and over again. I have tried all of the following without luck: Code Snippet For Each ctrl As Control In Me.FlowLayoutPanel1.Controls ctrl.Dispose() ctrl = Nothing Next GC.Collect() Me.FlowLayoutPanel1.Controls.Clear() Any ideas Thanks in advanced.

    - Getting string from Text Box sure. Everything is declared as Public strings in a module and pick2(i) is declared as a public instance of a structure. sub usetext With pick2(i) .Conveyor = txtconveyor.text .Reference = txtReference.Text 'More like this End With end sub The second time through the sub I get txtconveyor.text = "" and same with all the similiar lines. If I do this: sub gettext conveyortext=txtconveyor.text referencetext=txtreference.text end sub sub usetext With pick2(i) .Conveyor = conveyortext .Reference = ReferenceText 'More like this End With end sub Then it works and the string is assinged properly.

Does anyone know of a way to tell when a user is finished entering text into a text box. Are there any kind of windows events that represent that Other than a button click or another mouse click altogether, I can't think of a way.

Any suggestions

Thanks

Re: Windows Forms General Text Box Entry Finished

I think you will never know this, because only the user knows if he finishes typing what he wants....

unless you have pre-defined options, or use a limit of characters, I think it's impossible to do it

I use the KeyPress event. If the user presses the Enter key, focus goes to the next control. Example:

If e.KeyChar = Chr(13) then btnNext.Focus()

You can try either LostFocus event or Leave event,

Re: Windows Forms General Text Box Entry Finished

Ðãv? S. Â???????

Although this isn't full proof. The user can be done typing but still leave focus to the textbox. As said in a previous post, the only true way is if you have a character limit (which is still not full proof). Maybe make a button that the user must click when they are done typing, just a suggestion.
