I have the following combobox items:

I have a CheckedListBox with Items I also have a Stringarray which contains values from a DB All Items in the CheckedListBox ar checked, now i like to uncheck all items if there are in the StringArray.
Normaly i would do 2 for loops like Code is only pseudo - so no need to say it would not work this way
I know
' Loop though CheckedListBox
For i = 0 to CheckedListBox.count -1
' Loop though StrArray
For ii = 0 to Ubound(strArray)

I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.
I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.
I'm new to VB.net and i wanted to find out how i could load the names of files(in a specified dir) into a combobox?
1. get the number of files in specified dir
2. add names of files as items in combobox (using a loop structure)
3. when an item is selected. display the contents in a textbox[code]...
I added a few items in the combobox dropdown list at the form load event. [code] At the runtime I dont want to allow the user to write something in the combobox as a text.The user can only select an item from the dropdown list of the combobox.
View 13 RepliesI have a little problem, nothing very serious, but something that anoys me and i can�t solve.
I have a VB.NET windows form project, with a main MDI form containing a menu.
I load all forms with:
Private Sub MostrarFormulario(ByRef formulario As Form)
Try
formulario.MdiParent = Me
formulario.BackgroundImage = Me.BackgroundImage
formulario.BackgroundImageLayout = Me.BackgroundImageLayout
[Code]...
When show the form, i can see all combos / grids / objects being placed and feeded. Its a fraction of second (in fast machines). All my objects placing and loading are made in the Activated event.(because some combos data may have been added/deleted and the app can have multiples form oppened at the same time).
Is there a method for loading everything first (not showing) and then display all at the same time?
I have this code inside am event in a combobox. Because I don't know the placement off the textbox before I have run the code in the combobox:
Dim txttotal As TextBox
txttotal = New TextBox
txttotal.Name = "txttotal"
txttotal.Location = New System.Drawing.Point(x4, y)
txttotal.Size = New System.Drawing.Size(100, 15)
txttotal.TextAlign = HorizontalAlignment.Right
Me.TabPage3.Controls.Add(txttotal)
I can see the textbox thats works fine. But in another event I will give txttotal a value
But get the error txttotal not declared.
I am using VB.NET together with ADO.NET to create a program. I have set my TableAdapters as needed and bound the correct tables-columns to my comboboxes.My problem though is this:My combobox2 item is bound to a datatable. The table adapter's Fill method (the select command basicaly) includes a public variable in the where clause to fetch the correct results. I ll put some code here to clarify it a bit more.Public Class Frm_inv

I have on my form a combobox, a datetimepicker, a button and a unbound datagridview. The datagrigview is fild with data like a yearcalender.So i have in first column all dates of januari, then a blanc column, then the dates of februari, then a blanc column and so on...This is wat the user will do :
select his name from the combobox, select a date from the datetimepicker and press the button.What i would like to happen then is this : Find in the datagridview the same date as the selected one and then place the selected name in the blanc cell next to that date.
compare two strings is equalto and remove element in both and get remaining element string using vb.net
View 2 Repliesi have been coding for years, but never integrated XML. So I guess I'm a newbie. I have inserted an XSD file in my project, ARequest.xsd. I created a folder in my project called XML just to organize things, so this file ARequest.xsd, is in this folder.
Now I have a form that displays data from a database that has the same fields that are in this XSD file. Can I load the XSD file into my Windows Form, load the elements from the data on the windows form and then create an XML file then send it? If so how? Any code snippets would be helpful. Now I do know how to create the XML file, we'll call it Test as

I have an .avi video (500 MB-50 minutes) that I embedded using the following code in VB.NET:

Worked fine except that it took approx 5 minutes to load. Converted it to a wmv file (cutting it down to 300 MB) and it started playing instantly while it download. Unfortunately there are some computers that will not play it for some reason. It will load and the timer starts up as if the video is playing but there is just a black screen. I ran some tests and determined that it's not a browser issue.
How can I upload a video that instantly plays on all computers?

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.

I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.
Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....
I'm using the following code for doing so:
Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database

I'm trying to populate it with the results from a table in a dataset, something like Dim MyStringArray() as string = {Me.MyDataset.MyUsers.Rows.Tostring}. So I would end up with, StringArray() = {"Bob", "Jane", "Sally"}. I know I'm missing something very simple but I'm just not getting it.
View 5 RepliesI have a menu strip. In the menu strip I have something for some saved urls in the database, I called it Bookmarks. So I'm trying to fetch the items from the database and have it load in to the menu items.. but it keeps adding items and I only want them added once.

Like I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.
View 1 RepliesI found it unusaul that I can't load my toolbox items of my Visual Basic 2008 SDK after I just intalled Microsoft Windows7 Phone SDK. And, my property items are not complete, only the property of the main form is displayed, the properties of the controls in the form can't be displayed. I tried right clicking on the toolbox area -> choose items... and then I got this unusual message "an error occured loading this property".
View 1 RepliesThis one has me stumped. My listview which is called Xlistview1 I would like for when the form opens it will automatically load the example.text file to the listview and also when the form closes to save it. And one more thing I would also like to give users the option to save it by browsing as well a save and load button. Is it possible to have both of these?
View 1 RepliesI've got a problem, I'm making a program that gives you the choice to add items to a listbox, these items are text. When the form loads, i need it to load text from a file into a listbox. For every line I need it to add that text to the listbox. My problem is when it loads, there's an extra line, but that's only after I close the form and open it again. The reason it happens when the form unloads is because the listbox items are saved on form unload. Now, I believe the problem is my code to save the items:
Dim Env As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
For Each item In Form1.TP1.Items
Dim Save As New SaveFileDialog()
