I want to allow the user to enter symbols using the keyboard. I'm checking the textbox onkeydown event for the pressed key and then change it to a symbol, for example if I would press 'a' then the textbox would show '☺'. But the problem is that the textbox shows both 'a' and '☺'. Is there a better event to check this, or better way to do this?[code]...

View 10 RepliesThe title says it all, I'm having some difficulties with the combobox, The items in the list are "Black & Green" - Black will be the Backcolor of a Text box, and Green will be the Forecolor.The App I made is just a Mimic of a CMD, and replicates the output of the command into the Textbox. It's 100% complete, but I'd love it to have the ability to have different colors to choose rather than White and Black.

View 10 RepliesI populate a hash table with the name of a control as the key and the control itself as the value using the following code that loops through my code on start-up:
Private Sub Populate_Hash_Table()
For Each ctrl As Control In Me.Controls
For Each member As Control In ctrl.Controls
[Code]....
This method works effectively, but the only problem is I seem to get a preformance hit as it takes a second to set the current control to false and the new one's visibility to true. What way should I modify my code so that it works more efficiently?
If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.
View 6 RepliesI have a problem with the code, I have input the valid username and password in the form textbox to input the strings in php, but it keep displaying the messagebox that says login failed.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MessageBox.Show("Please enter your username")
ElseIf Textbox2.Text = Nothing Then
MessageBox.Show("Please enter your password")
Else

I don't really know why it keep displaying the messagebox that says it failed when I have input the valid strings in the first place.
My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.

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 have two combobox in a form: Cb1 and Cb2
When I load the form, Cb1 and Cb2 are connected to a bindingsource.
When I change Cb1, the code (below) changes Cb2 to show only the items according to Cb1
This is working fine.
The problem is when I change Cb1 , change Cb2 and click the save button..... Cb2 seems to be 'lost'...
I'm using VS2008.
CODE:
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 have a combobox that is linked to a database, but when an item is selected it is changing the name of the top item to the selected name. im sure this is happing because it is its text value and not it selectitem value, is there anyway to stop text input so it becomes a selected value rather than a text property

I have two textbox controls and I want to accept input for textbox 1 and textbox 2. However, when user enters text into textbox 1 I would like textbox 2 to mirror the same text as it is typed.
I am sure this is a very simple procedure however it is new to me and I am having trouble finding an answer with search engines. Most result are coming back as text that one can read backwards in a mirror which is not what I am looking for.
How to make a combobox only list based on user's input via autocomplete?For example, if user input "A" the combobox only lists all names start letter "A".If user input "AM" the combobox only lists all names start first two letter as "AM" and so on.
View 6 RepliesI've already found evidence of another having this problem. You can see this on this post by someone else:
http:groups.google...096b3fcaa?pli=1
The problem is that when one navigates the combobox via the keyboard, the combobox's information doesn't update. If you click a value with your mouse, though, everything works wonderfully. The link I've mentioned suggests changing the binding from the Text property to the SelectedItem property. I'm very deep into this project and it would be a bit of a nuisance to change the setup so as to allow it to be bound to the SelectedItem property.What I'm wondering is whether or not I can detect the user changing the selected entry in the combobox and tell VB that they "clicked" the value, if that makes any sense.
whats wrong with my code?if i change the item from the combo box..the textbox not change or has an error?
