i have a combobox in my form and i need to databind it from database i need to know is it posible to databind the combobox with image and text together like first show an image and than a text for each item.
View 1 RepliesAfter listing the data from data base to combo box, I would like bind the chosen data from combo box to textbox.
'bind from combo box to textbox

I have try using this code to bind the data from combo box to textbox, but unsuccessful to display the data in textbox. Is there any code that I left behind?
Is it possible to BOTH set a comboboxes datasource AND databind the selected value?Ihave 2 comboboxes on a form that I want to populate with data from 1 table,ut I want the actual selected values on each of the comboboxes to come from separate columns n another datasource Right now if one combobox changes, so does the other if that makes sense.
Here's a sample of code:
'Bind DataSource
With cboYields

Dim cn As New OleDbConnection
Dim sql As String
Dim da As OleDbDataAdapter

I have a LinkLabel on a form that has its Text property bound to a strongly-typed DataSet. When the user closes the page, I call BindingContext.Item(_ds.UserSettings).EndCurrentEdit() and then serialize the data if _ds.HasChanges = True. However, HasChanges is always False.
Has anyone else done this with a LinkLabel?
I just like the LinkLabel in this scenario. I guess I could hide a TextBox off of the side of the form and bind to it, instead.
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?
View 5 RepliesI'm making a front end to dvdauthor.I have a picturebox which holds the menu background. In order to draw a textbutton on the background image I store the image in a hidden picturebox. So the text doesn't get drawn to the visible background.
Dim ctl As Control
For Each c As Control In pbMenu1.Controls
If c.GetType() Is GetType(TextBtn) Then[code]...
This works the first time. But if I hit save again it writes the text to the background image on pbMenu1.
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.
I had added the items
1
2
3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.

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.
I need a code that will load text, the correct image to match it and the command for each image. what i want to do is make a program that will download a swf and an image into to folders. then at startup the program will load all the swf and images and put the images into a listview so when you click on the image for the swf file it will give the link to the swf so it can be loaded.

i have an assignemnt in my visual basic express 2008 class, were i have to type in an image name, like paris.jpeg,and automatically manipulate the file to be called paris-steg.png. Once this happens i click the manipulate image button and the image should be altered so that paris-steg.png has a message hidden in it. Then i have to decode that message. At this point im having troubel getting the file name to automatically appear as paris-steg.jpeg, and you will proabbly see why with my code. I need to know how to do this. The way i have it, i basiaclly add -steg.png onto the text typed into the text box, this doesnt work when the user types in paris.jpeg as it comes out as paris.jpeg-steg.png. heres the instructiosn and my code
(6) When the text file does not exist, alert the user with a message box and do not do any further processing.

In this program you should read text from a file one character at a time instead of one line at a time. If <tt>sr</tt> is an IO.StreamReader, then <tt>sr.Read()</tt> will return an integer that is the value of the next character in the file. Use <tt>Read</tt> instead of <tt>ReadLine</tt> in this program.You can check whether a file exists by using the code <tt>IO.File.Exists(filename )</tt> . The function will return a Boolean value (True if the file exists but False if not).
You can check whether a string ends with a specified pattern by using the <tt>EndsWidth(pattern )</tt> function. For example, if <tt>s</tt> is a String, then <tt>s.EndsWidth(".txt")</tt> will return a Boolean value (True if <tt>s</tt> ends with the pattern but False otherwise).In a string, <tt>IndexOf(pattern )</tt> gives the first position where the pattern exists, but <tt>LastIndexOf</tt> gives the very last position where the pattern exists.The code <tt>s = Chr(i)</tt> converts the Integer <tt>i</tt> into a character and assigns the character to the string <tt>s</tt> .
So I have a custom control that acts like a combobox and I want to use a custom background image for it. I also want to use a custom hover color and remove those white borders or set them to transparent as seen in the picture below.

I have a picture box on my form along with a combo box with a number of different options. So anyway when a combo box item is selected I want it to look in the dataset for the selected item's row and pick out the image to load and then using an IF statement it sets the image (or should).
Dim RaceImg As String = DS.Tables("tblRaces").Rows(ID).Item("RaceImg")
If RaceImg = "AusGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/AusGP.png")
ElseIf RaceImg = "MalGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/MalGP.png")
End If
I have tried a number of different ways to get this working, I have tried them in the resources for the program and also tried the following code
GP_Picture.Image = "./Track Images/AusGP.png"
It seems like the picture box isn't redrawing or something? Just to add it will load the first image which is the AusGP because thats the first option in the combo box, after that none of the others will load.
I'm using VB 2008 express to create a windows form application. I have a combobox named cb_face. The items in the combobox are image file names populated from my resource folder using a "for each" loop. When an item is selected I would like to display the image in picturebox1. I have tried several different codes but none of them display the image. I am not getting any errors. The comment lines show some of the code that has been tried.

View 2 RepliesI got a Combobox with some items (item1-item7) to select and 54ish Buttons(sButton1-sButton54). Also an array(53) called Buttons. The array is filled with the items to select, like: Buttons(0) = "item 1, item 2" Everytime another item in the Combobox is selected, I'd like only some of the Buttons to change their Image. Therefore I got the array. If Item 1 is selected and Buttons(0) contains the item1 I'd like to change the Button1's image.edit: It works with changing the image of every Button:
sButton1.Image = My.Resources.image1
But I'd prefer to change all in one go (Loop) instead.
sButton(0) = "item1, item2, item3"
sButton(1) = "item2, item3"
sButton(2) = "item1, item3"
