i have 2 windows forms, form1 and form2.form1 has a label called "label1" and a button called "button1".This button when pressed, opens up Form2.Form2 has a textbox, "textbox1" and a button. This button, called "button2", when clicked does this:form1.label1.text=textbox1.textThis used to work PERFECTLY, but now it does not work! i dont know what went wrong, and ive made a lot of changes to the project so i cant track the last time it worked.
View 4 RepliesWhen I set a control to "enabled = false", I want the textbox backcolor and forecolor to remain clear and distinct (white and back - respectively). Is there a place in VS 08 where I can define default appearnce for disabled controls? Or is there a beter way to lock control values other than using "enabled", that woulddn't affect apperance?
View 4 RepliesI've been dealing with this kind of problem in many cases now, I try to edit the properties of a button or a label or smth else from a backgroundworker or a timer and I would get the "Cross-thread operation not valid: Control 'Label' accessed from a thread other than the thread it was created on." Now what I am dealing with in the backgroundworker is 3 things: reading/writing to labels' names, editing the checked state of some checkboxes and changing the enabled property of some buttons/pictureboxes. Check the screenshot for more info.
View 2 RepliesWe are trying to modify a program to control a usb relay device. Essentially what the program originally does is give you a series of check boxes that you check to make the relay fire. We tried to modify the code so that the box is checked after 5 seconds using a counter and an if statement. It works, but only partially, what happens is the check box shows a check, but the even that is normally triggered does not happen. [code]

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?
View 1 RepliesI'm trying to make a label control transparent over a Panel control.However by setting the background colour of the label to Transparent, it actually sees right through to the form itself, not the panel as intended.
As an example we use a panel with a background as white, we make the label transparent, however it gets the form�s colour as blue.However, we are using a custom panel control and need the label to be transparent over the panel and not see the forms background.
i have a splitter control on tab 2, a grid and a scheduler control on tab 3..looks fine...i save it....close the form...reopen the form, and the controls are all resized and moved around on me....and not for the better.
wierd thing is that when i run the app, the controls are placed properly, but design time is totally f&*ked up.I know this one isn't me. is it the tab control? should i just do toggle buttons at the top and show/hide my own panels? this is just too freaky to deal with. is there an easy work around for this?
I have a winform project which I'm converting from a web project. In the web project I display "Notes" data from a data table into a table in three distinct parts. First the header, where the text color is based on the priority of the note. The second part is a short description of the note content and the third part is the complete note. The question I have is what is the best control for this in winforms? I guess I could use a text box and use it like a web text area. The data will be read only and will need to scroll since the amount of real estate on the screen accounts for only about a third of a 1024 X 768 screen.
View 3 RepliesIDE: VB.NET (2008)I have an mdi form in my program. As usual this mdi form acts like a container to several child forms. However, I need to implement a tabbed system so that my forms rather than appearing in mdi form should appear in a tab page.So I inserted a tab control on my mdi form and when a form is added I say TabPage1.Controls.Add(Form). It seems to be working okay until I found out that now my form is like a control so methods like Me.GetActiveMDIChild etc won't work.
Generally when a particular child form is selected we can know when we see the titlebar. In this case because forms are added as controls there is no difference in the titlebar of a selected or non selected form.Can I determine which form is selected. Something like Me.ActiveMdiChild. I can go through control collection of a tab page to get a list of forms but figuring out which form is selected is something I don't know.
I have the code which checks if there is a selected tab
Private Function GetBrowser() As WebBrowser
If TabControl1.SelectedTab IsNot Nothing Then
For Each c As Control In TabControl1.SelectedTab.Controls
If TypeOf (c) Is WebBrowser Then
Return c

View 1 RepliesI'm quite new at this but I'm trying to change the look of a tab control other than the options provided in the control's properties. In short I want to create a large tab that will fit a picture but I don't know how to change the size of the tab. I also want to make the control look somewhat different than what the control provided with VS.NET looks like.
What I need to know is how to create a custom control that operates the same as tabcontrol but looks different than the traditional control provided with VS. I tried looking up how to create a custom control but all I could find was how to create one programatically and I don't know how it would apply to a tab control. Maybe the only way to do it is programmatically but I would rather play with the control in the designer than having it appear only at runtime.

View 3 RepliesIn my app I have a pause and continue button. I capture the last active control when pause is clicked, change the Backcolor to let the user know where they were, from blue to red and leave the cursor there. What I would like to do without disabling and enabling all the controls on the form is to keep the cursor in the LastActiveControl no matter what until the continue button is clicked. In other words, tab, enter key, mouse click or nothing will make the cursor move until continue is clicked. Sound possible?

View 3 RepliesI am developing a windows app in VS2008 to be used along side ESRI�s ArcMap. Most ArcMap users will have dual monitors and I would like the user to be able to choose which monitor my app is loaded on to.
When I deploy the app using the standard install package, the app will load onto which ever monitor the user places the desktop shortcut. However, when using the ClickOnce method of deployment, the placement of the shortcut does not matter and the app always loads on the primary display monitor.
Is there a way to control where an app is loaded by code or any other method?
