I'm trying to display the population of a city, as soon as it has been chosen in the combobox.I put it on my formload, and it will always read the index of -1 since it hasnt had a chance to be chosen, how would I bypass this without a button being clicked?
If cboCities.SelectedIndex <> -1 Then
lblCurrentPop.Text = "The current population is: " & CStr(intPopulation(9))
Else
MessageBox.Show("You must select a city!")

I've got a pretty big datagridview that I have to populate, and it's already (with not loads of data) taking quite a long time to populate. I can't imagine it's possible in my situation to bind the datagridview to the data I want to populate, but here is the situation.
I want the column headers along the top to be a bunch of users, which I have in one data table. I want the row headers along the side to be skill names, whihc I have in another data table, and the data in the middle is the score of each user for each skill in data table 3. Some users don't have a score, some do.
The way I have achieved this at present is to create the columns first using data table 1, then for each skill (data table 2), create an array of rows from data table 3 that match the skill, find the matching user (ColumnIndex) for each of these rows, and fill in the score.

I have searched the forums for an answer to this problem and while I have found simalar issuses, I have not found a solution that works for me. I have created a dataset and populated it. I know that this is true because I can view the information in the dataset in other ways such as using labels or textboxes. However to display the data in a organized and usable way I would like to display the information in a DataGridView control. I DO NOT need to be able to modify or add anything to the datagridview, JUST view the information there. I am not using any wizards to complete this and so I need to be able to complete everything programmaticly. I have written the code involved to the best of my understanding. When I run the application, there are no crashes or errors thrown, I just can't get the datagridview to populate. Below is the code that I am currently using:

I thought this might be a common thing but I have not found any thing concerning this.For this example lets say the root folder is C:TestingFolder ListIn the folder "Folder List" directory there are 5 folders as such:

I have data codes in the format abcd123, abcd345,... present in the table Info of database.I want to drop abcd from code and display remaining code in a combobox of datagridview.
Code:
Dim dsCodeList As New DataSet
Dim dtCodeList As New DataTable
[code]....
It is giving error at first statement inside for loop saying Column Code Does not belong to Table Info.If i write simple query without use of right function and use dtCodeList.Rows(i).Item("Code").substring() to ignore first 5 characters, it works well.

Create an application that will predict the approximate size of a population organisms. The user should select or enter the starting number of organisms in a combo box, enter the average daily population increase (as a percentage) in a text box and select or enter the number of days the organisms will be left to multiply in another combo box. For example, assume the user enters the following values:
Starting number of organisms: 2
Average daily increase: 30%
Number of days to multiply 10
The application should display th following table of data.Day Approximate Population 1 2 2 2.6 (table should list values up to 10 days)
Be sure to add appropriate ToolTips for each control on the form.Input validation: Do not accept a number less than 2 for the starting size of the population. Do not accept a negative number for the average daily population increase. Do not accept a number less than 1 for the number of days the organisms will multiply.
