I'm having a problem with my form: all controls are suddenly insvisible! They are still working, though. It looks like this now: [URL] The menu items File, Edit, View and Extra used to be in the yellow bar above, but now they're gone, just like the status labels in the yellow bar below.

am trying to make use of inheritance to keep consistency in my user control appearance. I created a usercontrol to use as my base design, as a platform to link to a tab as acontainer. To this I added a few framing visual items like a header panel andsome labels.I then created another usercontrol that inherits from my base control, with the intention of adding the necessary items to this derived control to build it into a complete functional usercontrol that I can associate with a tab on my main form. I want to keep the visual appearance consistent across all similar derived controls. Then later if I change the design of the base form, this flows through to the derived controls.

My concept is to use the same form space to display different "pages", like a "wizard" where you click the [Next] button, and the current UI disappears and a new UI appears.

View 1 RepliesI wanted to know if there is a way to stop my webbrowser control from steeling my cursors focus? i mean its bad enough i have to hear the god damn thing in the background as it refreshes the pages.
What i built is basically a program that checks my marks on my school website and verifies to see if any new grades have been added. The program then notifies me by sending a text message to my phone. The program is in its beta stage and has lots of sloppy logic and code. anyways i hope someone knows how to keep my focus from running off of msn when I'm trying to type.
And as for the variables and coding. i know i have made it sloppy with unnecessary variables. I'm planning on cleaning that up when i have the time.
I have a few problems with making a map editor, how to make one reply and ill give you my msn well actually this problem: its not making the grid invisible if you de-deselect the option "Grid On" because the rect's have already been drawn. So I need to know how you can delete them.

I'm currently working on a WinForms project using .NET v3.5 due to limitations imposed by a 3rd party API that I have to use.
For the project I have to include some graphs however I've no budget (surprise, surprise) to purchase 3rd party controls & the graph controls within .NET v3.5 dont have that elusive "wow" factor that I'm looking for.
The chart controls in .NET v4 (MS version of the Dundas controls) are just what I'm looking for but I unfortunately cant use them as the 3rd party API won't work in v4 & there are no plans to have it upgraded to v4 compatable anytime soon
Does anyone have a pointer to any good (& free) chart controls that I could use ?
I have a form populated with controls. Short of looping through every control and hiding them, is there a way I can draw something like a message over them using the form's paint event? Or would I be better off putting an actual control in the middle of the form over all the controls?

What i want to do is grab the handle of a webbroswer control and only read the co-ordinates within those bounds. I have successfully manager to do this but the problem i am now having is moving the mouse to those co-ordinates, for some reason after getting the handle and moving the mouse:
Windows.Forms.Cursor.Position = WebBrowser1.PointToClient(New Point(x, y))
It still reads full screen co-ordinates.

View 19 RepliesI'm new to vb but acquainted with programming in java, C, and other languages. I'm developing an application and I'm having difficulties at commanding controls from different forms. It's like this: Form1 has some buttons and charts, and in Form2 it's a "Settings" form to select the category and series for the charts. When i close the Form2 I need to activate some controls like buttons in Form1 and the problem is that at run-time I can call functions like this one:
In Form1:
Public Sub EnableButton()
button1.Enabled = True
End Sub
In Form2:
Public Sub BeforeClosing()
Form1.EnableButton()
Me.close()
End Sub
Using breaks I can see that they execute and the properties of the button change but after the close event of Form2, the properties of the button1 control become unchanged. At the global variables I have:
Dim newChart As System.Windows.Forms.DataVisualization.Charting.Chart
At ButtonX_Click i create a new chart and define some properties and in the end i activate the Form2
Private Sub ButtonSettings_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonSettings.Click
[Code] .....
So the sequence is:
Form1 Execute: Button_Settings_Click -> initialize chart and Form2.Show()
Happens: Chart Initialized and properties are changed Form2
Execute: Button_OK_Click -> Form1.Button_ShowChart.PerformClick() and Me.Close()
Happens: Sub .PerformClick() executes but values are not changed Form1
Execute: Button_ShowChart_Click -> Add data to Chart
Happens: Chart is found as NULL and properties are lost
Why does the controls properties are lost if they are executed???
Is it possible to resize my controls on my form when I run it? The problem I have is that I have created a windows application which has a maximize state on all forms but on some machines my controls go missing (mostly on widescreen laptops). Ideally some way of resizing my controls would probably be best? So is that possible?
View 10 RepliesI'm trying to load a file where this file has, like, 10 lines. And I want to load each line (0 to 9) to each TextBox in my app (TextBox1 until TextBox10). So, there's a way to do this with a counter?
Like this mine code (that doesn't works):
If (System.IO.File.Exists("configs.ini")) Then
Dim configs As String() = System.IO.File.ReadAllText("configs.ini").Split(vbNewLine)
Const Max As Integer = 9
Dim TextBoxes(Max) As TextBox
For i = 0 To Max
TextBoxes(i + 1).Text = configs(i)
Next
End If
I am working on a project that I want to allow the user to move and resize controls in a panel container at runtime, much like the developer can do in the IDE.Is there a mode (not sure its the right term) I can implement on a selected control that will show the grab handles and allow moving and such?
View 6 RepliesI have a form that searches a db. Some searches will always result in one row of data, others might return multiple rows. I want to have the data from a single row shown in text boxes and the multiple rows show in a datagridview is it possible to hide/show those depending on the amount of rows.
View 6 RepliesBasically what I have are two loops, one inside the other, that will run until the given condition is met. Exactly what I want. My problem is that I want to be able to use the controls, like buttons, while a loop is going on.
I originally did not think of this until I had built this part of my program, what I want to know is if there is a way to use controls while a loop is going on or if their is an alternative.
1)I know timers can be used to meet these goals, but they did not work out as I had hoped and using two timers (1 to represent each loop) I do not believe is efficient.
2)I have considered using recursion, but have found this may not be very efficient either and am not quite sure if this will do what I want.
These loops run as long as the number the user inputted. So it could theoretically run for 100,000+ times. I am not looking for speed, but it would be good if there were a faster method that allowed me to use controls while it loops.
I want to be able to use a loop and reference controls using a string. The following code works for textboxes.
dim myControl as Control
dim ControlName as string
dim LoopCount as Integer
For LoopCount = 1 to 3

In the project I'm working on, I was editing a class and when I got done, I clicked save all. I moved on to my main form's designer. When it came up, the custom tab control I have on the form was blank. There used to be a ton of controls in it, so I am extremely confused about where everything went.I checked the properties window and it thinks everything is still there:ut when I check the Document Outline window, everything is gone. The tab control is still there, "AVERT Wizard", but all of it's child controls and tab pages are gone.
View 2 RepliesI've run in to a very annoying situation. At the moment I have a program with 4 forms. 3 of these forms work fine, but the fourth seems to be a dud. After clicking any one of the buttons or controls on this form it works. But if I try to click anything again, it doesn't work. I can't use my back buttons, I can't even use the minimize, maximize and exit buttons in the top right corner which are automatically built in to the program. I fear I have accidentally changed a setting, or accidentally deleted some very crucial code for this
