I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.

I am writing a GUI application with C++ Visual component Libraries and Win32API under windows OS.
As part of this app, I have to change color of the MS Windows button control depending on the external state.
I understood, Win32 will not support changing button control color directly as it will not support for this.

Ive set up one form that has two labels at the top (Western, Eastern). Below that I have a tabcontrol that contains two tabs (Sales, Products)
I have added four user controls:
WesternSales
WesternProducts
EasternSales
EasternProducts
The idea is that when you click on one of the labels (Western or Eastern) you access the tabs relevant to that region.
So, If i click on the "Western" label and then the "Sales" tab, the program loads the WesternSales usercontrol into the Sales tab. Likewise, if I click on the Eastern label and then the Sales Tab, the program loads the EasternSales usercontrol into the Sales tab, etc.
I want to eliminate the need for multiple data adapters. How can I load data from our database into each of the respective usercontrols using one data adapter?
So I am upgrading the system from 3.5 .NET to 4.5.1 and fixing any bug that I could find. Long story short, I run into an issue that basically tell me it couldn't find the images in the resource file. I figured out a work around, but first I have to set the picture box or background Image in design time to none. I ran into this Properties Windows while changing the value of picturebox for my user control saying: Property value is not valid. Object reference not set to an instance of an object. This usercontrol is taken from another user control from a different project. Basically, we are reusing it.
View 9 Replies View RelatedI am wondering what the best way would be for me to pass a piece of data between all of my different windows and user controls in my program.
Would i have to pass it separately between them e.g. add a piece of code into the button click event that will open the new window.
Or is there a way i can make it so that it is declared in the first window and then is accessible by all other windows and user controls.
Note: this is using WPF.

is there a way to tell WPF that I'm going to do a lengthy update on a control (TextBlock), and that it shouldn't redraw it until I tell it I'm done? I'm adding a large number of items to the Inlines property, and it has to redraw the entire control every time I add an item, which takes a very long time - about 1 second for every 100 items. I know some other frameworks allow freezing of certain controls, but I haven't been able to find anything in the documentation or on google. I've tried collapsing the TextBlock, and then making it visible again after the update, but it did not improve the performance at all.

is there any way to have the program control go some two paths at once? For example: if my program has two functions, one that does some simple calculation that requires nothing from outside it to set the variables and another that displays text for the user to read then enter something. Is there any way to have both run at the same time?
simpleFnc()
{int a = 1;
int b = 2 ;
int c = a+b ;
[code]....
There is no connection of simplefnc to anywhere else in the program so is there any way to get it to run at the same time the other function is running?
