Program In Vb That Includes A Combobox With A Textbox On Top And A List Box
Mar 11, 2010
I am trying to make a simple program in vb that includes a combobox with a textbox on top and a list box. Basically, the user should be able to type somthing in the textbox, click a button which adds it to the combobox, then click another button which adds it to the listbox. I have all of this done fine, but i am running into some trouble and have some questions.
First, theres a textbox right ontop of my combo box. I would like the textbox text to display whatever value is selected in the combobox. right now its just always blank because the textbox is on top.
Next, if the item from the combobox is added to the listbox, you should not be able to delete it from the combo box. how would i achieve this?
Finally, i need to create a function named "is included" that searches the listbox to check if a certain value is included in the list box. This search just needs to return true or false. I have no idea where to start with this part or what i should do.
Public Class ItunesKiller
Private Sub AddButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddButton.Click

I have a form with a textbox that holds data relating to job priority. txtPriority.Text = "Low" or "High" I have an amend button on the form that when clicked displays a cmbPriority object with a list that has "Low" and "High" in the list. When I click the amend button I want to the cmbPriority.SelectedText to = whatever is in txtPriority.Text. The item in the field will always be in the list. I have my combo box set to cmbPriority.Dropdownliststyle = DropDownList.

I have a form on which I want the user to be able to select a name from a list. The list needs to be populated from an table in my dataset. I'd like the user to begin typing and have an autocomplete append select type feature let them zero in on the person they want as they type. My question is, what type of control would work best for this?

ive created a program in VB 2008 and i cant remember how to publish it in such a way that it includes the database that the program uses. At the moment when i publish it, it only works on my system because i have the database on my PC, if i delete the database from my pc the program messes up because it doesnt have a copy of the database in its program resources etc.how do i publish the program so that it includes a copy of the database that it needs to function?

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

how to get my compiled program onto another computer. I'm using Visual Studio 2010 Professional.
I've read and tried ClickOnce deployment and Setup Installer, but I'm not getting it right.
With ClickOnce, I manage to install the program and it has the menu item and icon in the Start menu, but when I try and run it, it tells me that it can't find the text file. I put the file in the bin Debug and Release folders, selected 'Build' then 'Publish' and still no go.
I tried the other option of creating an Installer (using [URL] as my guide), but I get the same error - the txt file can't be found.
I've done this several times, but just can't seem to get it to work. Other resources online, like YouTube, just cover a project that doesn't include a text file or database file etc.

I've been working creating a few programs in visual studio 10. These work fine on my own PC because I have the .net framework installed. However I need to be able to distribute these programs as a single .exe file download from our website and also as a single .exe file via CD.
Most of the PCs which will be installing my programs won't have .net framework installed and I don't want to force people to have to download the files from the internet (it just seems like so much hassle and I can't guarantee that everyone who wants to install my programs will even have access to the internet).I know that I can set pre-requisites in the publish tab and I have done this whilst setting "Download prerequisites from the same location as my application". I've already downloaded the redistributable files WindowsInstaller-KB893803-v2-x86.exe and dotNetFx40_Full_x86_x64 and I've put the files in the same folder as my project.I then go into the publish wizard and select that users will install the application from a CD-ROM or DVD-ROM. Unfortunately I then get the following errors:
Error 2 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'WindowsInstaller3_1WindowsInstaller-KB893803-v2-x86.exe' in item 'Windows Installer 3.1' can not be located on disk. See Help for more information.ConsumptionCalculatorDraft1
Error 3 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'DotNetFX40dotNetFx40_Full_x86_x64.exe' in item 'Microsoft .NET Framework 4 (x86 and x64)' can not be located on disk. See Help for more information.

I have a problem here. I want to distribute .net framework and windows installer along with my app installation file. The questions:1. Is it legal? Windows installer, yes it is legal. I don't know about .net framework 3.52. Which folder do I have to put the files? I tried the publish, debug, and root folder of the application, none works. I select download from the same location of my application in clickonce.

I have a form which is bound to a table that includes information about properties (real estate). Each property can have a number of inspections. These inspections are included in a separate table.
I want to use the form to show the property information and a data repeater to show all the inspections for that property.I can't seem to get the data repeater to bind to the inspection table and pull only those records related to the property information table. In fact, the data repeater shows nothing.
I can get a data repeater to show all the records in the inspection table when I put the control on its own form, for testing purposes.

I am using a simple regular expression (in C#) to find a whole word within a block of text.
The word may appear at the beginning, end or in the middle of a the text or sentence with in the text.
The expression I have been using word has been working fine however if the word included a special character (that has been escaped) it no longer works. The boundary is essential so that we do not pick up words such as vb.net as a match for .net.[code]...
