3. Enter some text not in the drop down list or leave the combobox text blank
4. Click the form close button ( the "X" )
5. The error will be displayed, "ERROR - Invalid Entry!"
6. Press OK on the messagebox
This is where something goes wrong. If you click the Dropdown arrow of the combobox, the dropdown list wont stay open. ( unless you hold the mouse button down ). This doesn't happen if you click or tab to another control (like a text box). Then after the messagebox is displayed the ComboBox still works fine.
how to add items in combobox1 that will be saved....this pattern isn't do the way i want...Form2.ComboBox1.Items.Add("test") because after i close the form2 it would be back to nothing...is there a code that will do this? because it works only in design view...in items then collection..
I would like to have a combobox with 5 names in Combobox1. Calgary, Edmonton, Denver, Kelowna & Toronto. When I select Calgary I would like the numbers 01 to show up in the Textbox1. When I select Edmonton I would like the numbers 02 to show up in the Textbox1. When I select Denver I would like the numbers 03 to show up in the Textbox1. Etc........
on Form1, i have a combobox1 where i have 15 values. im using a case statement with those 15 values to decide what is the next form to go to. i need to make sure the user cannot add in his own text to it or click the NEXT button without having any value at all. how do i add these "exceptions" to my code?
i would think any exception would go before the case so that it could tell you didnt put in the right answer before it looks through the case statment and give you a nullexceptionhandler reference.
I am really baffled and can't work out why this is happening. I have this code with transfers text from a textbox and adds it to combox items. My problem is that after the combox has got 2 items init, anymore you add there will be muliple of them and not just one for example:
I've created one form with TextBox1, TextBox2, ComboBox1. Then when I click one of the ComboBox1 items I want to load the saved settings and display them in the TextBox1 and TextBox2. The settings are:
I have a weird behavior with tabs on a VB.NET form.On a form I have several comboboxes, text boxes, and 2 buttons.I have made sure my tabindex are in the order I desire, meaning combobox1 has tabindex 1, combobox2 tabindex 2, button1 tabindex5,etc..Here is the behavior, when I first open the form, if I tab from combobox1 it jumps directly to the button, instead of combobox2, however once I help things with the mouse, it will tab in the appropriate order.
I have a button called 'populate'. I need it to randomly select items in combobox1 when I click it. Here is what I have tried doing but it doesn't give me the desired results.
Dim sacostofsyscheckout As Integer Randomize() sacostofsyscheckout = CInt(CInt((1500000 * Rnd()) + 3000000))
I want to learn how to populate a combobox so if a vlaue is selected in another combobox then it will be invisible for selection. You can NOT use combobox1.items.remove since my box is bound to a datasource.So I either need to create a new query and adapter and bind the combobox2 to that query, or fill combobox2 from combobox1 minus the selected item in combobox1. Either way I need some help writing code correctly.I have tried a few different ways but not succesful, I was probably on the right track a few times but I am still not very proficent in code writing.This is the code I have written so far for my program, I deleted all my attempts at remove selected item since none worked and were just confusing.
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click OpenFileDialog1.InitialDirectory = "c:\" OpenFileDialog1.Filter = "CSV Files (*.csv)|*.csv|Text Files (*.txt)|*.txt" OpenFileDialog1.ShowDialog()
I have one table from where two comboboxes get their drop down lists, showing info that has been entered into the table (boxes are bound to the table columns I.E City (Box1) and Country (Box2). what I would like to do is if a city is selected in box1 then box2 will autofill with the country name.
In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?
new to VB and having some problems with my code.the story is that while marking items in comboBox1 need to pass values to 3 different comboBoxes so far I have made code that pass data only to one comboBox. [code]
I'm trying to play around with combo boxes and trying to figure out how to navigate to a certain url in webbrowser1 depending on the text selected in combobox1.
I have added 2 Combobox on form. Combobox1 and Combobox2. I have connected databasetable to Combobox1.
i.e. Showing items of Combobox1 from database table column A.i.e. displayed one column of databasetable in Combobox1.Same way I have connected same databasetable but different column B to Combobox2.
So,What I am trying to do is :Once the form is set up for run then I click on Combox1 item Then I want Combox2 to display only the item of B column that is in the row of column A ( selected item in combobox1).
Is anyone able to understand my question here?If u have understood then do reply If my question is not understandable then let me know what part U din't understand so that I can elaborate
i'm still needing help to my "Download file names into Combobox1 from webserver's folder".I have folder at my webserver http://127.0.0.1/FolderName/ and inside my folder is alot of .txt files and here is few of them: A,B,C and D.txt file.
So when form loads i want my application download file names what are in my webserver folder TO Combobox1 then Combobox1 may look like this.
i have form1 with combobox1 and rtb1 i would like to search the rtb1 for combobox1 selected value and return the first 9 characters from the line with the result.

I'm currently making a Web Browser, and I was wondering how I can save History after I close the program/form and clicking on the site I visited last and navigate to the link with a single click?
I am using memorystream to get and store images into sqlserver 2005 table image field. This process is working and I am able to display image in picture box. I need to be able to store PDF files into the same field and be able to display in a picture box.
I'm attempting to copy a rather complex form from one part of my project and use it (modified) within another part (ie, depending on whether it's maintenance or an outage, you'll get a slightly different email screen).
My first attempt failed miserably, as I had simply right-clicked and pasted the form within the project, assuming renaming the controls would work. nope, I didn't realise that there was stuff in the original form that was renamed as well, and that created a monstrous pile of errors.My second through fourth attempts also failed, generating errors in forms that (I thought) weren't related or connected. Once I deleted the copied form, all was fine.
So, short of trying to rebuild the form from scratch (using a different naming convention for my controls etc.), is there a simple way of doing this? This seems to be such a simple task, but alas I was wrong....(or, at least it's not easy with the information I have right now.
How do i can make combobox list to be File names like:
[Combobox1] - A.txt - B.txt - C.txt
I want Combobox list to be files from my webserver [URL] and i want it pickup them example if here is NERD.txt i want it pickup name NERD.txt from my webserver and include it for a one of the list items.
I have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.
I have been creating a call management application and I am having a problem with something that I have spent weeks on trying to get working and nothing I try is working for me. My application is an MDI application written in VB.NET 2005 Professional, using .NET Framework 2.0. It uses a back end database using Microsoft SQL Server 2005.When the MDI application launches, a form is displayed to the end user asking for phone number (MaskedTextBox) and a partner name. The partner names are within a ComboBox.
When the end user types in the phone number and selects a value from within the ComboBox, s/he clicks on the start button. This then opens a second form. The phone number from the MaskedTextBox is to default in a second MaskedTextBox (this I am able to get working without issue.) The partner name selected from the ComboBox is to default on the second ComboBox. This is the part where I have been working on it for weeks and not able to get it to function.
The second form has many ComboBoxes, all of which pull down items from a particular table within the database. Some of them are editable and some are not. The ones that are editable are also auto complete Suggest/Append on the ListItems.I wrote a sub to handle the population of these ComboBoxes and also to handle if they are editable or not. All of this is working. However, my main issue is that I can't get the value on the second form to default to what ever was selected on the first form. I do not get any errors but regardless of what I do, the second form always stays as the first item in the list regardless.
The code I am using is as follows:
<CLSCompliant(True)> Public Sub PopulateDropDownListFromDB(ByVal cboName As Elegant.Ui.ComboBox, _ ByVal TableName As String, ByVal ColumnName As String, _ ByVal UseAutoComplete As Boolean, _ ByVal UseSQLDistinct As Boolean)
simple problem Basically in form1 i have a line of SQL code in a rich text box called rtb_select
what i would like..This code to run under a connection string called strSQLSelectQuery in form2
I have been told someting like strSQLselectQuery = rtb_select.text would work however because rtb_select is in a different form in the same project it does not recognise rtb_Select
I'm making a game maker, and I just need to know how to put the buttons on the form. where to add the button code in the Form1.Designer.vb file? I just need to know what the syntax of InitializeComponent is.
