VS 2008 File Names From Comboboxes?
Nov 28, 2010
I have a ComboBox with several names within it. The names are sourced from a database. Once the user has selected a name from the ComboBox, he must input the no. of hours from another ComboBox and then he is able save it to a .txt file through a streamwriter.
Here is a little image I just put together:I want the file name of the .txt file to be whatever is selected from the first combobox. So, by using the example shown above, the file would be called bob.txt. Is this possible?There shouldn't be any save file dialog or anything, I want it to be automated and the name of the .txt file to be selected from the ComboBox.

This is the code I have in one button and I have 2 listboxes that will be filled with the info it gets.This code should compare 1 avi file to one jpg file and see if they have the same name. If YES then it will add the avi path to one listbox. If they don't have the same name OR the .jpg doesn't exists it will add avi path to another listbox.. But currently it is adding the avi name to both listboxes.

I am creating files and then allowing the User to browse through the files via a ComboBox. I decided to name each file the current date. In order to create multiple reports each time the application is ran, each report needs a unique name.
The idea is that if they run a report once a day they'll have a unique report each day. But, then I realized that it is feasible that User could run a report more than once a day. So, I decided to create an integer and increment it each time the report has been ran. Then append the file name with that integer. So, report one of that day would show something like this:
12-22-2009_1 and so on.And this works just fine. But, if the user decides to close the app and then run the report later that day, the variable has been reset and no longer works as needed.I'm using a StreamWriter to create the file.

this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):

I need to send a switches and a filename to a command line application.First I'll need to get a collection of files that can range from 0 to an infinite amount.Then I can start the process with the correct switches. Normally, within the command line application, I would specify the specific filename and send it as an argument to the application.However, I'm not sure how I would do this. The names of the files have to be preceeded by a specific switch. I can't remember the switch right now, but we'll call it [b]-f[/f].[code]So, I need to figure out how to send all or each of the file names as an argument.

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

Alternatively, if anyone knows how to get an ftp file object using .Net 2.0 instead of an html string that would be even better.

I am experiencing a problem when trying to convert a rather large VB6 application into a .Net 2005 application. Everytime I try to convert the project I get the following error: "Upgrade Failed: Exception occurred: Can't use character device names in file names"The weird thing is i have tried to convert the project using .Net 2003 and I do not get the error, it does convert.

Lets say we have an Access file in a well known path (i.e. "C:MyFolderMyFile.mdb"). That file does not have a primary key set on the table we are interested in . Is it possible to set one of the fields as a primary key (for example the "ID" field , which is also an AutoNumber data) ? And one more thing : I'd like to change the name of a field on that table . For example , lets say there is a field called "My Field 1" (note the space characters) and we want it to be renamed as "My_Field_1" . If it's possible , I'd like both these changes to be permanent in the data base file itself , not just in the imported DataSet ,

I'm program that uses quite a few different comboboxes. Essentially drop down boxes to prevent invalid user input. Anyways, the problem I've run into is when I'm loading files that will populate those combo boxes. Essentially, certain selection in the combo boxes invalidate selections in other boxes. What I'm doing is taking a text file, and reading it line by line. Each line is based off the combo box selections previously made and saved using the same application. Returning to the same screen, I want to populate the combo boxes with the data previously selected.
I'm initially populating the combo boxes in program with
<combo box>.Items.Add()
Other than searching item by item for the proper text, getting the index of of that text, and then setting that as the selected item?
So what I'm thinking of doing is this...
Dim Fin As System.IO.StreamReader
Fin = System.IO.OpenText(FileName)
Dim sInput As String
Dim iIndex As Integer

I need to build a SQL statement.
I have 3 ComboBoxes that i need to use for my SELECT statement. This means that if the user selects ONE of them the SQL statement will be different than when he chooses TWO or THREE.
If none is select, then ALL data is displayed.

I have a program issue I am trying to work on. I have multiple comboboxes(12 total) on a form.I am attempting to update some settings from what ever the user selects from the combo boxes. I am trying to keep the code as small as possible, so I thought about having all the comboboxes have similar names only different by a number being changed at the end. (ex: cbo_1, cbo_2, cbo_3, etc...)And using a For next loop to advance through each combobox and update the settings as the for next loop advances.(This might be a stupid way of doing it, but its the first idea that came to mind.)

I need to select all the comboboxes on a form with a for each loop. I have about 19 comboboxes and I need to select each one. I tried to do
for each box as combobox in me.controls
But that gave me an error and i now tried this:
for each box as control in me.controls
if box.name.contains("ComboBox") then
...
end if
next
That selected only the comboboxes but the problem is i need to access some data that is specific to comboboxes (aka the selected item(s), if its blank) but those properties are not present since "box" is a control, not a combo box.

1) Does this code make text the selected items text? If it doesnt then how would I do that?Dim text As String text = ListBox1.SelectedItem.ToString()
2)How would I make it so that if in combobox.items there is an item with the same text as the listbox selecteditem it is removed? This is what I have and it doesnt work.
If ComboBox3.Items.Item(text) Then
ComboBox3.Items.Remove(text)
End If

This post is a continuation of my other post concerning 'List(of) with multiple comboboxes refill problem.'. I threw the list overboard and began anew with a Dataview.
So far I (finally) managed to get 2 comboboxes (will be more, but if it works for 2...) loaded with the same data using different dataviews (DataView1 & DataView2) so I can select a value from each combobox without the other following the selection.
But now I want to filter out the selected value from the other combobox.
This also works.
The only thing is this: If I select in combobox1 the value 3, and select in combobox2 the value 4, combobox1 will change to the value 2.
If I select in combobox1 the value 2, and select in combobox2 the value 1, combobox1 will change to the value 3.
It works also the other way arround. I can't seem to get my hands around the problem..
Does somehow the index of the items in the combobox play's part? I don't use the selectedIndex, so from my point of view it can't be..
The code I use:
(with the item 0 as 'neutral' option)
Public Class Form1

I'm trying to make a program in which I can import an excel file, read the whole thing and save it in another format. So far so good: can import the file, read it, skip first line or not etc.But.. Now I've been thinking about a sort option.What if the column order of the excel file is in another order than the export file must be in. In stead of opening the excel file and rearrange the columns manually, I would like to sort it in the program. Just for the sake of trying to make it work and gain experience
So, i read the first line which contains the column names and put them in several comboboxes where I can make a selection. No problem here.Now, the selection of combobox1 has to be removed from the other comboboxes and so on, to avoid double selections on one column. That's where my listOld comes in. Everytime a selection is made in a combobox, a sub is called to create the listOld and create the listNew (which contains items you can still choose from).As I make more selections the listOld gains more items and the ListNew grows shorter.But here comes the part where I'm puzzled.In the part "refill the comboboxes" (bottom part) when I disable "cmb2.Items.Clear()" the listOld (previous selected items) contains all selected items correctly.

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")
It's the same problem for all of my File System commands. Either file not found or invalid arguments.
The complete script I'm using is here:
Code:
Sub Main()
Dim arrArgs() As String = Command.Split(","), _

I'm trying to make a program that'll play the card game "War". I've started to code the dealing process, but it doesn't seem to be working. I currently have 3 comboboxes on the form each with numbers representing different cards, 1 that contains all the cards to be dealt, 1 that contains the user's cards, and 1 that contains the computer's cards. I plan to just draw random numbers from these comboboxes for the dealing. However, nothing happens when I click the tool-strip button that's supposed to deal the cards. [Code]
