I have a combobox and a rich text box. When I select different items in the combo box, I want some text to appear in the rtb next to it. Such as, selecting "Dog" in the combobox puts "Golden retriever, lab" and etc in the rtb.
1) I don't know what kind of event handler would trigger the combobox. I tried a click event but it's crashing so I want to know if there's a different way
2) How do I find what the user selected in the combobox, so it can display stuff in the rtb accordingly? I thought it was .Items.IndexOf but nothing seems to be working so.
i wan to display the text from combobox into the textbox and clear the combobox text when click on the button.But when i select another text from the combobox and click the button, the textbox display and overwrite the previous text.How can i do so that when click, textbox display text from combobox and clear combobox text. Then click again, display the new text at 2nd line of the textbox without deleting the previous text?
basically i'm making a webbrowser, and i want it to select and option from a dropdown ComboBox, on a certain button click. I use this code which i found it on these forums as well:
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("select") If element.GetAttribute("id") = "wrapper_opacity" element.SetAttribute("value", "51")[code].....
The problem with this code is that it just inputs the selected value, but it doesn't really SELECT it.The option selected is shown, but not activated.
I am working on a school project to display a photo of a professor when their name is selected using a RadioButton and to display their name, office office hours and so on.
I have their Photos in a directory on my computer
Theonly thing I cannot figure out is how to use 1 picturebox and link the image to display to the radiobutton.
I have tried all kinds of queries on the internet and cannot locate the answer. There might be something with an Image.FromFile command I saw but that might have been from a previous version of VB and I could not get it to work in VB9.
Web browser question from stupid newb: How do you make the url of your current web page show up in the navigation combobox or textbox?The actual problem is when I go to a web page and click an internal link or use the back or forward button it only shows whatever the last webpage I keyed in and not the actual page I'm on.

I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles Rock 4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.
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.
When I will click the suggested text shown in the combobox it will disappear.My Combobox btw is connected in a database.If I type Kev then kevin and kevsky will show at its suggestion then when I will click any of it ,the combobox text will be empty or will clear what I typed ("Kev") and will not show what I clicked.[code]
I have a combobox..... When a user clicks on the list inside the combobox my webbrowser opens to the selected items website.how to make the combobox go back to the original text of the combobox?
Example: Combobox list ---- Select Item ---- Royals Mets
[code]....
When the user see's the screen the ---- Select Item ---- is visible. When a user clicks a teams name it opens the teams website and the name stays in the box. I want it to go back to ---- Select Item ---- immediately after they click a list item.
Brand new to VB 2008 Express, but have done some work in VB 6. Not sure what I'm missing, but here goes. I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US.
This is what I used for the Table Adapter Configuration Wizard for the combobox "State" SELECT ST_UID, ST_NAME FROM STATE
For the combobox County I used: SELECT ST_UID, CTY_NAME FROM COUNTY ST_UID is an Integer.
I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5).
The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state.
I then tried to convert the value in the st_uid label to an integer:
CODE:
This is what I last tried when again using the Table Adapter Configuration Wizard for the table that populates the County box: SELECT ST_UID, CNTY_NAME FROM COUNTY Where ST_UID = 'StUID' Order By st_uid, cnty_name
What I'm getting is a "Data type mismatch in criteria expression." I'm sure my error is something so simple.
Hello, everyone! I'm having problems with the Activated Event in Visual Basic. When trying to click my btnNext, IF THE DATA ON THE PAGE IS NOT SAVED YET, then a message box is to appear and alert the user that the data is not saved yet. When clicking the OK button on the MessageBox, it is supposed to return control back over to the main form. HOWEVER, I can't get past the Activated Event on the main form. It crashes the program. I've tried global flags, but it still does not want to work! Can anyone please help? Any thought in the right direction will be greatly appreciated! Thanks in advance, y'all!
I am trying to migrate a vb6.0 application to vb.net. I have a major issue while executing the code under form.activated and form.deactivate. There is a difference in behaviour between form.activate in vb6.0 and form.activated in vb.net. How can I simulate the behaviour of vb version in vb.net.
I have read that the form.activated fires even when the control goes to a different application and comes back.
I recently upgraded an application from VB 6.0 to VB.NET. This application contains a timer in its form (only one form is there). But after upgrading, the timer is not getting activated. Form is using DefInstance as follows: frmMain.DefInstance.Show()
I need to create a program that when it is opened, Focus will be always in that program until someone with any way will close it. I've tried to add Me.GetFocus() in the LostFocus event but nothing happens, I've tried to add Me.activate() when the Deactivate() event raises and when I debugged the program worked but when I run the biulded .exe file nothing happens again! how I can manage this Function?
This is a non-MDI windows application. I have a home form containing a panel named Panel1 and two buttons btnForm1 and btnForm2. Clicking btnForm1 and btnForm2 opens up Form1 and Form2 respectively in Panel1. Before a form is opened in Panel1, all opened forms in Panel1 are cleared. The code follows:[code...]
In which events should the above lines be written? In MDI apps this could have been accomplished by including them in Form_Activated and Form_Deactivate events respectively.
But here neither Activated nor Deactivate events fire when you open forms in frmHome.Panel1. Instead of Activated and Deactivate you can use Form_Load an Form_FormClosed events but they will only merge/unmerge menus if existing forms are closed before opening a new form in the panel.
But as I sometimes need forms to be opened and closed keeping existing forms opened, using these events won't fulfill the task. Even the GotFocus and LostFocus events won't work. So I want Activated and Deactivate events to be fired or some other means by which the menus and toolstrips can be merged/unmerged when the form gains/looses focus respectively.
I am trying to switch from a SingleCall Remoting infrastructue to a client activated object infrastructure. But can't get it to work. Probbaly a setting. On the hosting server (a console application) I have:
We are converting a Visual Basic 6.0 application to vb.net 2008 and are having an issue, while executing the code under form activated event. There is a difference in behavior between form.activate in Visual Basic 6.0 and form.activated in vb.net. In Visual Basic 6.0, the Activate event was raised only when switching between forms in the application; in Visual Basic .NET, the Activated event also is raised in case of showing messagebox and when switching from other applications.(by msdn)
In vb6 application the purpose to use form activate event is, to execute some code when forms become active. In our application forms are loaded, hide and show in different flows. So whenever this form is shown from hide state or any of its child form return focus to it, we need to reflect different changes in the application to the specific form controls.
* For example user changes its application preferred language. * As the application is huge, so shifting logic to other place with respect to the current scenario might solve the problem for the current form but then I have to re think it for all other forms (which is very hectic and more or less not feasible). In the migration process it is required to make as little changes in the existing code execution hierarchy. So we need a similar behavior like form.activate in vb6.0 with some other event or restrict some functionality of Activated event in vb.net.
I'm trying to make it where you can click make a dialogbox lose focus until you input the requested information. I'm trying to create an effect where if you try clicking on the parent form, it flashes and won't let you activate it. You can see this effect in Windows sometimes when an error box pops up and you have to click 'OK' to continue. How would I go about doing this in VB.NET?

I have one combobox and 2 picture box in my form. The idea is that, when combobox selects "1202", the picture box 1 should show the photo from the resources with name "1202" or "1202.jpg" and the picture box 2 should show the photo from resources with name "NK1202" Here is the code I have to desplay photo in picture box1[code]...
I have completed this code, but I cant seem to get the answer into the combobox?
Dim mydatabase As String = DatabaseNameComboBox.Text Dim TableNaming As String = TableNameComboBox.Text Dim DatabaseConn As New OleDbConnection Dim DatabaseConnString As New OleDbConnectionStringBuilder Dim strSQL As String = "Select * from " & TableNaming & "" [Code] .....
This last line, just adds the select * from statement, but I want the column names?
I want to have a combobox, but I have two fields from my Access table that I want to display in my Combobox. I want to show the entire row in the combobox. Do I need use an asterisk at the line for adding items to the combobox? [code]...
