View 1 RepliesI have made my program but I want to give users the option of choosing a custom color for text. I have an inputbox that works and then converts it to Color.whatever. But seeing as the user types in what they want and it is not done by the program itself it can throw exceptions.
Dim directresponse As String
Dim actualcolor As String
Dim isgood As Boolean
[code]....
That is my Sub, it will make Color.(userinput) but I need to check if Color.(userinput) is actually a color that VB.NET can understand and add set.
I have tried "System.Drawing.Color" I get told it is a type and cannot be used in this context.use System.ComponentModel.TypeDescriptor to convert it to a color and check if it is real and then set it.
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've been working on C# web applications for a few years now, but my boss threw me a curve ball in the shape of a VB.NET Windows application project.

I would like to center the text that appears in a combobox.
What I enter the code or the procedure?
I am using VS 2008 to develop a VB application which has a tabcontrol. On the 3rd tabpage is a combobox, set with DropDownStyle as "DropDown" to allow free text to be entered as well as selecting from the loaded items. My application allows for values to be saved to disk and reloaded.
What I'm finding is that when then application is 1st started, if the tabpage containing the combobox has not yet been accessed, and a value is loaded from disk by the application into the combox's text property ( I have verified this using by Debug.Print statement, and using a Watch), when the tabpage containing the combobox is selected (I add a break on the "TabControl1_SelectedIndexChanged" event to check the text value) the text value is cleared to equal "".

I have a combobox with whose contents get populated via code. Works ok. But When I select something in the list and hit 'OK' it always returns as: nothing, "", or -1 (tried with .selectedValue, .SelectedText, and .SelectedIndex respectively)
Question is, How do you access the text in a ComboBox's selected Value??
Need some direction not looking for code,
How do I add text such as 'please select' to a bound combobox that populates from parameters?
I want to make this text the selected index 0.
I am using VS2008 on Windows XP SP3. I have a form with two pairs of dependant comboboxes which are bound to a SQL database table. In each pair, the second combobox's choices are dependant upon the selection of the first combobox.
Both pairs of comboboxes behave as expected. However, when I use the binding navigator to look through other existing records, the text in the second pair of comboboxes disappears on records that already have selections.
The database table still holds the information, but it just doesn't display in the combobox. Again, this only happens on the second pair of comboboxes, not the first pair and both sets of comboboxes are set up exactly the same (albeit on different tables).
