Remove Filearray(0) Index At Certain Times?
Mar 2, 2010
I am creating a program which really relies on arrays to work.Everything is working well except for trying to remove an array index. I need to remove filearray(0) index at certain times and have not found an appropriate way to do this. There might be more elements after (0) but there also might not be. I can't seem to come up with the code that can remove index (0) as if the rest of the array is blank I'm not sure if I can redim from lbound(+1) to ubound())

I want to display a bitmap on my form, and then remove it at times, and put it back again.
I have the Bitmap in my resources folder.in my form properties, it is selected as background image.
somewhere in my code I set the background image to = nothing (that makes it disappear) but every time I try to bring it back, I get file not found.I got it to display when I hard-coded the entire path and filename.[code..]
Obviously, when I publish and distribute to clients, the file won't be there.[code...]

I have multiple tabs in a tab control, and I need to know how to remove a tab by its tabindex, I can't seem to figure it out. I don't want to select the tab, just close it.

How do I remove an item from an array at a specified index? This code copy's the index and then adds the indexes until it gets to the one you want to remove, skip it, and try to continue. But I get so many errors. From being out of the bounds of the array, to just being null for some odd reason. [Code]

Im building a, lets say kiosk, that has only one form of input and that is a keyboard. I've got an up/down/left/right arrows and the enter button. I have a form that needs to have hundreds of buttons. I've arranged all my buttons in a giant grid and want the user to use the arrows to navigate through the buttons. The button that is 'highlighted', lack of a better term, has different colors so we know which button we currently are on. So when the user hits the down arrow the button below the current button gets highlighted. My issue is that when the user hits the left and right arrows the 'cursor' doesnt move left and right it moves up and down.
The left and right arrows follow the tabindex sequence.

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

I have a datagridview, with 3 columns, each containing dropdown filters (in the column header). Of the 3 columns, 2 are working perfectly fine, but whenever I try to filter the 3rd column, it gives me this error: (Also all of the column's have the ColumnType property set to: DataGridViewAutoFilterTextBoxColumn) "Index was out of range. Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?

why the code...
Form1.Controls.Remove(myCustomControl) ...does not remove the control.
Because whenever I remove a control and add it again, it does not Load but rather just changes its visibility from false to true and all the variables are not reloaded.
I tried to use .Dispose() but VB.net tells me thatit can't access a disposed object whenever I try to add the control again.
