I need to allow labels in disabled panels to retain a their prominent forecolor. So, I am considering replacing all labels in panels that become disabled with LinkLabels. By disabling the control and setting its disabled color to black it holds the color. However, I have always been of the opinion that one should use the lightest control possible.
View 3 RepliesI'm trying to make custom ListBox with some graphics. Base is ItemCollection - each item contains Panel, 2x label and 2x picturebox. What each panel have to do:
- Change backcolor on MouseEnter and set color back when MouseLeave occurs.
- On MouseDown(LMB) - Panel stays "selected" - different color.
Problem: I can't access multiple panels at a time(and I need to), just one via sender as in function. Of course, I can do it hacky way, but I want to do it effective and regular. Is ItemCollection the right solution or should I do it just like an array of panels? Also I want them in one "box", ItemCollection is good for it.
Second "problem": I need to make labels "merged" in panels, when i MouseEnter them(labels), background color on that panel sets to my default color. when i MouseClick them(labels), nothing happens (need to "select" parent panel). It can be again fixed with hacky way, just disable labels - but then the colors of labels are unchangeable.
i've a datagridview control populated with records from database. i've formatted certain cells of datagridview according to a condition. (i mean i've set the fore color and back color of cell). But when i export these datagridview contents to excel 2003, no cell colors will be appearing.

View 3 RepliesIs there an "easy" way to change a control's ForeColor when it is diabled? Yes, I know that this goes against the Windows standard.
On our forms, we have buttons with a dark blue background and a white foreground (the design is dictated by marketing). When the buttons become disabled, the ForeColor goes to a dark color making the button unreadable.

View 2 RepliesApparently I don't understand what PointToScreen() is actually returning. I'm thinking it should be absolute screen co-ordinates. In a form, I have some labels in a panel, which itself is in a panel and am trying to derive the screen co-ordinates for the labels in one statement without adding the X and Y co-ordinates of the panels. Why does PointToScreen(Label.Location) return the same value as PointToClient(Label.Location) and the same as Label.Location? Shouldn't PointToScreen() return absolute SCREEN co-odinates?
View 12 RepliesThe appearance of the selected Tab on the tabcontrol is sort of subtle. I'd like to either change the font, make it bold or change its color. The .font property appears to be relative to the font on the tabpage---not the font on the tabcontrol tab.
Is there any way to change the tabcontrol tab so that the SelectedTab is more prominent?
I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?
View 1 RepliesWell im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...
With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.
View 7 RepliesMy assignment is to create an application that allows the user to type an item's price into a single textbox, add the price to the previously entered prices, and display the total charge which includes a $15 shipping charge and a 3% sales tax.Example: I type 10 in the textbox and click calculate. the subtotal (before tax and shipping) reads $10. Next, I type 20 in the textbox and click calculate. The subtotal should now read $30.I have everything working fine except adding the different prices. I cannot figure out how to retain the value of the subtotal and add it to the next value entered.

View 18 RepliesI'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.

View 2 RepliesI have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

In my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;
Dim PreviousCell As DataGridViewCell
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown

What i am trying to achieve is that if listbox2 contains checkedlistbox1 items then checkedlistbox1 should retain checked state even after the from is closed and re-opened again.
