DB/Reporting :: Usercontrol - Form - Press A Button That Opens A Text File And Populates The DataGrid
Jul 12, 2009
I have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,
A B C
1 2 3
3 4 4
3 1 3
Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?

The SaveFileDialog that opens up while clicking the export button of the CrystalReportViewer by default filters the predefined file types. Is it possible to custom define which files to be filtered?

I have built a program in where I have to add and remove items from two listboxes. Listbox1 consists of a file which I have picked up on my C:/. Within this file, are different lines of items. At the end of the item line is a figure. I have a textbox in where when someone adds the an item from listbox1 to listbox2. On clicking the add button, it will add the total which was in the file. If I add more items, it will give me a running total of the items I have added to listbox2.
Now, I'm bamboozled in how to subtract the items from listbox2 with the remove button. So that when a user wants to remove an item that they currently placed in Listbox2. On pressing remove it will subtract the running total from the item which has been removed.. Here is my code in where I add products to the textbox. I have two other text boxes which I use to have these running totals. FYI, Textbox where value is outputted is Textbox5. Textbox6 is used to refresh the data and the other textbox is named 'Total'.
Public Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
If ListBox1.SelectedIndex < 0 Then
MsgBox("Please select a Batch")
[code]....

My text file is something like what you see below, and I want to populate the datagrid. Once I populate the datagrid, I'll use that kind of like an excel spreadsheet in the sense that I'll dip in and grab values based on row and column index to display to the user. I will also (on a different form maybe) display the same datagrid to the users so they can sort by column at their choosing.[code]The error I am getting is: Value of type 'Integer' cannot be converted to 'System.Windows.Forms.DataGridViewCell'.

Here's what I'm attempting: The user browses for and opens a dbf file. The user is presented with a checkedlistbox which shows the column headers. The user then selects the columns they wish to run a report on. ex. total # of cells not empty, longest cell length, etc.
I'm to the point of populating the checkedlistbox with all of the columns shown but I'm unsure if the users selections are actually linked to my data and if they are how I go about isolating said selections for the reports. I have a feeling that my approach to populating the checkedlistbox is not the proper way for what I'm trying to accomplish.
Here is the code
Public Sub btnGetFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetFile.Click
Dim fileLookUp As New OpenFileDialog
[CODE]......................

I have created a button in a UserControl. I have added that button to a WindowsForm in another app and added a buttonclick event to the code. When running (debugging) the app and clicking on the button; nothing happens. It doesn't act like a button at all.
The code for the button click event in my test app is as follows:
Private Sub Element1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Element1.Click
MsgBox("The button has been clicked")
End Sub

I am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs
Private Sub searchTab_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles searchTab.SelectedIndexChanged
searchTab.TabPages(searchTab.TabPages.IndexOf(searchTab.SelectedTab)).Controls.Add(splitContainer1)

I am trying to build a form that has a button on it that will open up a 2nd form that allows me to view and edit the connection string. I believe the connection string is also called app.config, and can see that in the Solution Explorer for the project.All I have managed to do is drag a button onto my main form and relabel it. I have no idea how to create code to access the connection string.

I have a few questions. first, how do i make it so that when you open your program you can not open ctrl+alt+del = task manager? second how do i make it so that a button opens a .bat file? third Is it possible to a button open multiple Internet Explorer Windows? When i try to do this it only opens a bunch of tabs? and lastly how do I make it so that when it installs on a computer it installs straight to the start-up folder without the user knowing it, or how do you make it so it opens automatically on start-up?

Basically, I have developed one form which is generic and display different views. On that form I have used Close button. Alphabet E is short-cut for closing the form (i.e. mnemonic functionality).During execution of the form, when I press "E" on that form, my form closes automatically. As per my understanding mnemonic works with Alt control only. I am not sure if I am missing any properties that should be set so that this problem is resolved.

I have a Function Named Logout. Code is below;
Private Sub Logout()
Try
SendRequest("http:url....)[code]....
Everytime I login, It seems to run the logout function also. It DOES NOT do the SendRequest, but it does the me.client.dispose() which logs you out of chat. Is there a way where i can make this function only work when a button is pressed or the form is closing. In the form closing and btnLogout code I have Logout(), but I only want it to run that function when you close the form or you press the logout button, not when you log in. Is there anyway?

Good Evening! I am attempting to write a code so that someone can enter characters into a text box and then press a button which will validate the string and then count the number of uppercase letters in the displayed text. I also have a button that will allow lowercase tabulation. However I cannot get either to work or display in the associated text boxes.
