Forms :: Users To Enter Their Own Choices In And Then Their Choices Are Displayed Into The Gridview?
Apr 28, 2010
wondering if someone can help me some small issues I am having with building my first project.
1.I have comboboxes that allow users to enter their own choices in and then their choices are displayed into the gridview.
the problem I am having is this is allowing me to duplicate choices. for example:when I run debug to try my boxes, I can type in Johnathan into the combobox as many times as I want to and it adds is to the combobox list..so now I got 10 johnathans in my combo box.and then to make things worse, when I hit the button I made to send choices to display..it causes duplicated choices to show up in the display.What I figure is that it is easier for me to just prevent duplicates in combobox.
2.Lets say on one of 10 comboboxes I got...lets say someone skips the box and doesnt make a choice...my grid will then display the last choice made.. (man o man)for example:John chose in his boxes and is displayed on gridview: Combobox1 (john) Combo2 (5:00 PM) combo3 (waiting)now lets say I come up to the computer and in Combobox1(Dcurvez) Combo2( i skipped and didnt enter a choice) and Combobox3(In Progess)
The display will put Dcurvez....5:00 PM.....In Progress because I didnt make a choice in the time combobox..it put in the last choice (Johns) as 5:00 PM Can someone in very simple terms tell me how to fix this problem?? I am using visual studio 2008 and vb/vb.net as language this is not a webpage, btw. it is for in shop computer just.

how to save the users radio buttons choices to load into a file. I have a button which controls the If statements to determine the price of the configuration. I was wanting to save these choices that the user made. I thought I could do this by altering the If statements but I don't know if thats the right way. I've got 3 different groupboxes with 3 options in each.
Heres a part of the code for the IF statements:
Private Sub UpdateConfig_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpdateConfig.Click
If Choice1Option1.Checked = True And Choice2Option1.Checked = True And Choice3Option1.Checked = True Then
PriceShow.Text = Prices(0, 1)
TextBoxProcessor.Text = Choice1Option1.Text

I have 2 comboboxes, textbox and a cmdbutton. When the user makes a selection in one combobox I want it to filter the choices in the second combobox. Then when the user clicks the button it passes the values from the comboboxes to a stored procedure and populates a datagridview. I am using VB.net 2005 and sql server 2005.

I have two combo boxes, and four buttons. When the user clicks "Add" on the first combo box, it adds a new item to the combo box with "New" and then lets the user rename that item to something else. That "new" item has to have an array of "answers" that go along with that item in the list. What I'm having trouble figuring out is assigning "answers" to the second combobox for each item in the first combobox and changing the second combobox when selecting an item in the first combobox.
EXAMPLE:
Item 1 - Combobox1
- Item 1 - Combobox2
- Item 2 - Combobox2

We are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app. I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation. Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?

i'm trying to display a random messagebox that displays a message associated with a character. the character image displays and the user clicks a button to guess the character if it is correct, one of three messages should randomly appear that is associated with that character (there are 4 characters, so there are 12 possible messages total. 3 for each character) but as it stands now, the picture box on the form displays the character name so the user doesn't have to guess which button to push. i need to remove the name from beneath the picture so only the buttons have the name and the user is forced to guess and i don't have the messages randomly popping up. only a messabebox that says correct i added a message box in the code but i can't figure out how to randomly get the messages associated with the characters to appear?
Imports System.IO
Public Class Form1
Dim currImageIndex As Integer = 0
Dim characterNames As String() = New String() {"Donny", "Jesus", "Lebowski", "Walter"}

I am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2, specifically WinForms. In the DevExpress GridControl at runtime you can click on the right side of the column header and choose which values in the column you want to show. For example if your table contained:
Name1 Checked
Name2 Unchecked
Name3 Unchecked
Name4 Checked
Then if you click on the right side of the checkbox's header you can choose checked (or unchecked) and it would display only the data that is checked (or unchecked). In this case with checked you would have:
Name1 Checked
Name4 Checked
I was wondering if there was some way to override the names so instead of letting me choose checked or unchecked I could override it with 'owned' and 'rented' or 'active' and 'inactive' based on what the checkbox represents in that specific column.

I'm building a game using the traditional form view on VS2010 and I'm trying to change the colour of a label's text depending on its contents. I believe I've coded that fine, but the problem is that the settings for the label in the designer view pane are overriding my code!Is there a way to disable certain options in the designer view so that my code can work?

I have a project that has several combo boxes on one form. The selection in a box can affect the possible choices in subsequent boxes. Right now I am using SelectedValueChange to fire the code that loads the choices in the later boxes. There are a number of possible events that I could use:SelectedIndexChangedLeaveLostFocusTextChangedI was wondering if someone could give me a rough idea what the differences are between these. Is there a 'best' evnet to use?Also, I find that most events work when the choice is made with a mouse click but if you click in the box and type in a value an event does not fire. How can I program for the case where the user enters a value by typing it in instead of choosing from the drop down list?

In the following code, a local printer dialog box shows and its choices are implemented in the printout, but if the user goes to a 2nd-level printer dialog box such as by clicking an Advanced or Properties button, choices made therein (such as landscape/portrait or scaling) are not implemented in the printout (prfPrintForm is a PowerPacks.Printing.PrintForm on form frmPlotTrends). Is there something else that must be done to make the 2nd-level dialogs work?
Dim dlrResult As DialogResult = frmPlotTrends.dlgPrintDialog.ShowDialog()If (dlrResult = DialogResult.OK) Then frmPlotTrends.prfPrintForm.PrinterSettings.PrinterName = frmPlotTrends.dlgPrintDialog.PrinterSettings.PrinterName
frmPlotTrends.prfPrintForm.PrinterSettings.Copies = frmPlotTrends.dlgPrintDialog.PrinterSettings.Copies
frmPlotTrends.prfPrintForm.Print(frmPlotTrends.prfPrintForm.Form, Printing.PrintForm.PrintOption.ClientAreaOnly)End If

My form's KeyPreview is set to True. I want to allow my users to use the Enter Key instead of just the Tab key. I have the following code in my form's KeyPress event:

If e.KeyChar = vbkeyreturn Then

It doesn't like vbkeyreturn, which I used in Visual Basic 6.0. I think I must be close to having it right.

I have an app that has been localized in the usual fashion (i.e., .resx files), which handles about 95% of the strings. However, I still need to localize some strings for category names that are stored in the database. I'd like to avoid adding 15 new columns named categoryname_ES, categoryname_FR, etc, and then pulling the right column dynamically. If there would be some way to pull the data, and then do a substitution in the code, I think that would be a little less messy. Maybe along the lines of:
go through gridview row by row if the language selected isn't English, look for this text value in a global resources file and replace it. Or is adding a lot of categoryname columns for each language just the way to go (ewww).

Using a Windows Form with a Menu bar and a Gridview control, I have bound data to the GridView from an MS Access 2000 database query using Dataset. The contents of this table displays just fine. But I want to be able for the user to select a different query from the menu bar and display it in the same GridView control. How can I change the query bound to the control (in VB)?
Public Class Actinide Private Sub Minerals_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Actinide_Series__Radioactive_TableAdapter.Fill(Me.Minerals2000DataSet._Actinide_Series__Radioactive_) End Sub Private Sub LanthanideToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LanthanideToolStri
[code]....
The error message that it is giving me is:
"Value of type 'Mineralogy.Minerals2000DataSet.Yttrium_MineralsDa ta Table cannot be converted to
'Mineralogy.Minerals2000DataSet._Actinide_Series__ Radioactive_Data Table'.
The query is getting information from two seperate tables,so I can't just bind a table to the control and then filter what is displayed using SQL.

I've created a Gridview control that pulls some data from my database, but doesn't display all of the information I'm hoping it gathers. I choose not to display the primary key for user interface purposes, but require that key for basic operations on the grid.I'm currently attempting to add a "Delete" option to the table, but unfortunately I'm having very little luck. Here's my .aspx file.
<asp:GridView ID="ManagerList_GV" runat="server"
AutoGenerateColumns="False" AllowSorting="True"
DataKeyNames = "ManagerID" OnRowEditing="editManager"

We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?

When I originally set up my project I 'hard-coded' my username and password in so that I could access a remote DB2 database. Now that I need to publish it to other users they need to be prompted for their own usernames and passwords. I've gone to "My Project/Settings" and deleted the items from the string - but when I run I get the following message on the statement:
Me.BATCHTableAdapter.Fill(Me.DB1DataSet.BATCH)
ERROR [08001] [IBM] SQL30082N Security processing failed with reason "3" ("PASSWORD MISSING"). SQLSTATE=08001
The settings are as follows (before I delete the userid and password):
Name:DB1ConnectionString
Type:(Connection string)
Scope:Application
Value:Database=DB1;Server=99.999.999.99:446;userid=myuser;password=mypassword;Persist Security Info=True;
The question is what do I have to do to make it forget my userid and password - and always prompt the user for both when running up?
