I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!
View 9 RepliesI have five menu items that i have created as a user control and placed on the master page. Now i want one of the menu items to be visible only for particular user role and not visible for others. Here is what I did. Its not working though.

I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

View 3 RepliesI have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As

CODE:
I'm making an application with a custom progress bar (picture box) using the formula
pbxProgress.Width = (intValue / intMax) * pbxBar.Width
where pbxBar.Width is the maximum length.Along with that, I'm using another formula to change the RGB color of pbxProgress while it increases. I'm using:
pbxProgress.BackColor = Color.FromArgb(0, 0, (intColor / 255) * 650)
I came to that last number; 650, by guessing and checking. If I use that number, the RGB increases perfectly with the value of the progress bar so that it ends up being at 255 when the bar is completely full. The only trouble is, I'm not sure how I got that number, and I would like to make a more general formula for future use.

I'm attempting to use a ProgressBar to show while I'm loading a database. The table I'm loading isn't exceptionally large (about 7900 records), but my program nevertheless takes 39 seconds to load it! I think this is a little too long for a wait cursor, but I'm having problems figuring out how to use the ProgressBar properly.
I would show you what I've got in the way of code, but I trashed it (accidentally) and would like to start over the right way. Please just point me to some tutorials that make sense (if possible) or any code snippets, etc.P.S. I'm loading the database from a button_click event on my main form, which (eventually) raises my 2nd form which has the database displayed in a datagridview control.

View 4 RepliesI have a form called frmReport and on this form a user makes selections and clicks the "btnBuild" button which in turn creates a crystal report and displays it. However sometimes this process can take some time to build the report. So I placed a panel control along with a progress bar to let the user know that the system is working. However when the form runs the progressbar does not run until the last few seconds before the report is displayed. how to get the progressbar to "run" while the report is building ? (The progress bar is set to marquee.)

i create an apps which is capable of installing apk file on android phones. QuoteQuote: This is base on ADB command "adb install applcationname.apk"
we can install apk on command prompt using adb install command The scenario of my program is like this: all the command on cmd will appear on my form (This is all OKey) the apk's name is on my listbox1, if I select the items on listbox1, the name of this item will be written on my txtCommandInput (my textbox)
this is my sample codes
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Dim _items As String = ListBox1.Text

if you press the button it will throw the command from txtCommandInput.Text and the result will displayed on cmd, so the "adb install command" will run. all of this thing is working fine, except the progressbar Now im reading this book about progressbar and backgroundworker sad to say i really cannot make it work, that while the installation of this apk the progressbar value is exactly 100% after the installtion finished
how the progress on progressbar will be the exact value and result of this apk installation
