Fairly new to the VB.NET world, but a long time Access and FoxPro programmer.I'm trying to do something that was extremely easy in Access, but can't believe it is this difficult in VB.NET.I populated a combobox with values from a mySQL table. I want to return a hidden value from the combobox (Username), but the values that are being displayed are the full names (Firstname and Lastname). So the user selects the full name, but never sees the Username.
I've searched many different sites, and have seen examples that involve creating classes, and other complicated ways of doing it.This site explains what I am trying to do, where you select a City Name from the combobox, and it returns the zipcode. [URL].. However, the ValueMember/SelectedValue doesn't seem to work for me, or I am not understanding how it is used.or even a link showing my how this is done? I am just not finding the right info on my own.
I'm converting an old VB form to .NET, and there a few Buttons which each have a corresponding ComboBox hiding behind them. The previous behavior was that you'd click the Button, and that would trigger the ComboBox behind it, which would then drop down a selection list. I believe the idea was to have a static color and text label (which cannot be a selectable option in the drop-down list), with the functionality of a ComboBox.
Now, in VB.NET, clicking on the Button (which is directly over the ComboBox in the form) won't trigger the ComboBox dropdown anymore. However, if I make the ComboBox visible enough to click on, it will trigger the ComboBox.TextChanged event, and show the drop-down (they're set to the DropDownList style). I've set the event handler to handle both that event and the Button event. I've tried Button.MouseDown, Button.MouseClick, and Button.Click -- none of which have worked.
I did find the SplitButton control option suggested here, which would probably do the job, but I don't want to have to integrate a non-native control for just 3 buttons. I don't really want to mess with the control template, either
All I want is to enter text into a databound combo box. If the entry is not in the list, then the user should have the option of updating the table that the combo box is bound to.The way I have set up the project is by dragging objects from the toolbox and having the application set up the datasource through the data sources tab. This in turn creates the bindingsource, dataset and tableadapter.For updating the combobox I have added code into the leave event. This does indeed update the client table as required. However, the id stored in the quotes table is -1. How do I make sure that the correct id is stored that references the newly added client record. For your information, the client table only has an id and clientname column.
The code is as follows:
[CODE] Private Sub ClientComboBox_Leave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ClientComboBox.Leave Dim con As New OleDb.OleDbConnection Dim dsClients As New DataSet
I am writing a program that is connection to an oracle database using the tableadapter method. I am populating a drop down list with a distinct set of values. I am then wanting to display the item that user selects in a text box. However, instead of the desired result being displayed the text box is returning system.data.datarowview.
I am designing an clock-in/clock-out program as a learning exercise. So far I can type the name of an employee and add them to my timeclock database in a row called "EMPNAME". The issue I'm having now is that I need each of those employees in column of EMPNAME to appear in a combobox when I hit "GET LIST". Is there a simple way to do this using a SELECT statement for the commandtext? I've tried to google but cant find exactly what im looking for.
I want to make 5 attachment options in that 4 out of the 5 are hidden.but when he clicks "more attachment" link it will show the other 4.Im using ASP.NET with VB?
I have an ASP.NET web application (VB.NET) using an Oracle database. On an insert, I need to get the identity of the inserted row back. I am trying to use RETURNING, but I keep getting a value of 1 returned.
Dim strInsert As String = "INSERT INTO L.TRANSACTIONS (LOCATION_KEY, TRANS_CREATOR, TRANS_EMAIL, TRANS_PHONE) VALUES (:location_key, :trans_creator, :trans_email, :trans_phone) RETURNING TRANS_ID INTO :ukey"
My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".
Here is my code for all 3 forms.
code:
These are forms to calculate the cost of getting a cell phone package.
I am using VS2008 and creating forms. By default, the underscore of the character in a textbox when using an ampersand is not shown when I run the application. ex. "&Goto Here" is not underlining the G until I press the ALT key.Is there a way to have this underline the text that I put an ampersand in front of when the form/application starts instead of having to have the user press the alt key?
I have a little trouble with my code. You'll see. I'm using the developer express ridControl tool. I have a Gridview in it with a table bound to it. The control lets you filter your info. I have a Select all button that works, the only problem is that if you filter the data and press the select button it selects all the rows, not only the ones that are actually shown on the grid, and I need only the shown ones.
I have a grid column, of which, row X is hidden. I want to pick the values of each column's row x, perform some calculations at client side and display it in row y(through client side code). I am not able to pick values from hidden field in client side. Is there a way I can put those values in a client side array using javascript code, and use it for my calculations. Also when page posts back, the array should get updated with latest values.
I'm trying to find out a way to where you can tell if an HTMLobject is hidden or not. The code for the hidden object is in the document, but how do I tell if its being hidden in the browser or not?

I'm trying to run a console window hidden while using CreateProcess(I can't use the ProcessStartInfo class because I have to run it with some other special settings)I have tried to use the CREATE_NO_WINDOWS flag, but somehow, the console still pops up. This is the code I have:Dim ProzessInfo = New Process_InformationDim StartInfo = New Startup_Information, PS = New Security_Flags, TS = New Security_FlagsIf CreateProcess(Nothing, target, PS, TS, False, PROCESS_CREATION_FLAG.CREATE_NO_WINDOW,othing, Nothing, StartInfo, ProzessInfo) = 0 Then MsgBox("Couln't st
I'm using Windows Task Scheduler Wrapper to schedule the tasks (basically to launch an exe console every two minutes or so) in a .net desktop application.However, I don't want it to pop-up the console every 5 minutes or even once. How do I hide it? I understand if I was using vb.net to launch the exe, there are several things I could have done. However, I am using windows task scheduler to launch it.
I have a new application, and for some unknown reason, it's hidden behind other opened applications. It is shown when launched on desktop only if desktop is empty. How do I force my application to be in front of desktop ?
Followed Rob's webcast, did as he did, watched T4 generate the code, went to use the new namespace and oh. No namespace. I can see the namespace Test.Data in each of the generated .cs files, the tt files are included in the project as is subsonic.dll, there are no errors (I managed to get rid of a warning for the duplicate directives) but I just can't see the namespace. To test it out I am building a simple vb.net console application so wondering if there is a conflict there. Using v2.2 against the same db works fine.
I have a combo box that is tied to a binding source that loads a list of users from a table. Currently the list of users is a List of String object type. When a user selects one of the users from the drop down, a list is filtered down based on the selection. To do that I currently have to requery the User Table to grab the UserID column of the user selected, which seems a bit inefficient to me.
Is there a way that I can assign a custom object with two properties (UserName, UserID) and have only the User Name is displayed and when I have to filter the list, I already have the UserID, so there is no need to requery the database.
I am designing a program that will backup a user's profile in Windows XP. So far, the only snag I've come across is copying the 'Signatures' folder from 'C:Documents and SettingsUSERNAMEApplication Data$MicrosoftSignatures' I believe the issue is that the 'Application Data' folder is hidden.

is there another way to really execute this file hidden? i dont know how to do it but i heard about mabye threading it or making it a windows service? will that solve this?
I have made a validation application, the application runs in the tray and responds to events of another app such as save document, on this event my application runs, validates the document and creates a pop up message of errors in the document. However the pop-up is hidden behind the other application, the other application is locked because it is waiting for my app to finish. I have tried combinations of show(),activate(),bringtofront () with no success i have also tried SetForegroundWindow() and SwitchToThis Window() for win api but with these the app still just flashes orange in the taskbar behind the other application which is locked.I think it is almost definatly a problem with stealing focus from the other application but im not trying to make an annoying pop-up, it is needed and only appears when there are problems with the document the other application is locked and will not respond untill okay is clicked on the pop-up and it is easy to miss the flashing icon in the taskbar

Having come from the MS Access IDE, I have used hidden text boxes to store information needed on a given form. Often they are data-bound and the program needs to reference the data but the end user does not need to, or should not, see them.
I am very surprised to find that in .NET, you cannot do this. Making a control visible=false should be a UI decision, but the value should still be programaticaly available. Am I just missing something, or is this truly a limitation in .NET?
