I'm using VB 2005 and have an Edit - Entry form with Textboxes and several Comboboxes. I populate the Comboboxes with Arraylists as shown below. I populate a datatable with the Employee data from my SQL Server. I assign the BindingSource1.Datasource to my Datatable then add Databindings to the ComboControls. The (Fields.STAFF_MGR_ID.ToString) is from an Enum. When all is complete my textbox fields Bind and move with the MoveNext.. no problem, but the comboboxes display nothing.
Dim Manager2 As New ArrayList
While dr.Read
With Manager2
.Add(New ListContents(dr(1).ToString, CInt(dr(0))))

I have this form filled with data using dataset, data adapter
1 Dataset , 8 data adapters
Textboxes are ok and binding .. fills by 1 data adapter
ComboBoxs are filled by 7 data adapters
The problem is 6 ComboBoxes data is from one table filtered by id1 i.e.:
cmb1 : select id2,content from table2 where id1 = 1
cmb2 : select id2,content from table2 where id1 = 2
cmb3 : select id2,content from table2 where id1 = 3
........
Now how can I bind all ComboBoxs with textboxes?
I would like to create a button that clears textboxes and comboboxes when it is clicked. For example when 'btnClear' is clicked then txtDate gets cleared (i.e. txtDate is 22/05/2000 then when btnClear is clicked it has nothing in it)
I have already tried
txtDate = ""
and
txtDate = Nothing
but an error comes up.
so yesterday this code was working for my userforms and today its not. Its a simple clear command for textboxes and comboboxes. what is from here?
Dim ctl As Control
ForEach ctl In Controls
IfTypeOf ctl Is TextBox Then ctl.Text = ""
IfTypeOf ctl Is ComboBox Then ctl.Text = ""
Next ctl
I have a windows form on which there is a textbox and a command button. When user inputs an integer in the textbox and clicks on the button, the userform grows and adds that many number of comboboxes and textboxes in a panel.

The maximum value of that integer would be 10.
I have an edit Contact Form that pulls data from access and loads it into textboxes and comboboxes. The text is working fine, but I am trying to pull a number from the ddatabase and display that value in a combobox that already has selections in it, so the user can edit it. For example the combo box is filled with 1,000,000 - 60,000,000 and if the number in the database is 2,000,000 I wan the combobox to display 2,000,000 Here is the

I have tried selectedtext, selectedvalue, and selecteditem but none of them work because its a number.
I've been making a table control for a few days, and I've got to the point of making it capable of accepting new data. To do this, I'm making it generate a row of text boxes, combo boxes, and date selection windows along the row that you're entering data into.
I've tried using an array of 'control' types and changing them to whatever specific control I need as I generate it. That sort of works. For example, the code under 'Case "Employees"' below will make a combo box display on the form, but 'ControlArray(i).Items.Add' gives an error because it doesn't think that ControlArray(i) is actually a combobox yet.
You might also be interested to know that everything will have to be dynamically generated since the table I'm using will not always be the same (and the Select Case code will eventually be replaced by something that checks for relationships in the database).
Dim ControlArray(NumberOfColumns - 1) As Control
For i As Integer = 0 To NumberOfColumns - 1
ControlArray(i) = New TextBox

View 5 RepliesI have a button (named Test) and I have the X and Y coordinates of the 3 buttons (Which are A, B and C) to click. Now what I want to do is, when the Test(button) is pressed, timer1 (22 seconds) would start and after 22 seconds it presses automatically button A and if it isn't the right button then it will wait another 22 seconds and then presses button B and if it is right it will start another 22 seconds and if it is wrong it would start another 22 seconds and press button C. If the correct button was B then another 22 seconds would start and this time it would start again from A.
1.When Button TEST is press the timer will count down 22 seconds.
2.After 22 seconds it will press the button A (timer will stop)
3.If button A was the correct letter then Timer will count another 22seconds.
4.If button A was wrong it will start the timer (22seconds) and then press B (timer stopped).
5.If button B was correct, timer will start another 22 seconds (back to step 2)
6.If button B was wrong then timer will start and will click button C. (timer stopped)
7.If button C was correct then timer will start (Back to step 2)
8.Will continue like this until 25 clicks had been made then it will stop.
I have a question regarding clicking a button on a web page through the web browser control in VB .Net Express Edition. I have figured out quite a few tricks and stuff with the web browser control but I can't figure out how to automatically click a button. I know I can invoke the 1st instance of a "submit" type button but I want to click the 3rd instance (or chose which ever one I want). Unfortunately the button declarations in the HTML don't have ID or NAME tags to make it easy to pick them. How would I go about extracting all the buttons on a form in an array form, so I could invoke a certain member of that array and click a button of my choosing. Is this possible?

View 3 RepliesI'm making a program which will work minimized in the system tray.Now, what it have to do is to load a page [URL] and then input a specific string which i have stored, into this element:
HTML Code:
<input name="ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$txtUsername" type="text" id="ctl00_ctl00_JobnetBaseMiddelContent_LoginContentPlaceHolder_txtUsername" class="text required" style="width:183px;">
and another string into this one:
HTML Code:
<input name="ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$txtPassword" type="password" id="ctl00_ctl00_JobnetBaseMiddelContent_LoginContentPlaceHolder_txtPassword" class="text required" style="width:183px;">
and then press this button:
HTML Code:
<input type="submit" name="ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$btnLogon" value="Log ind" id="ctl00_ctl00_JobnetBaseMiddelContent_LoginContentPlaceHolder_btnLogon">
After that, it would login to the website, and would afterwards press on another button.Each week, i have to login to a website, and press a button in order to keep my current economic status. Which is quite meaningless. Therefore, having a program to press it for me, working in the background, would be so much easier, and make me not forget it?

I know how to grab all the links of a page, and I tried using that same principle to grab the buttons, but I'm not exactly sure how to click one based on a certain parameter.
Here's what I'm trying to do. When the page completes (this code is obviously under Document_Completed), the program should grab all of the buttons on a page and go through each of them, and if any of them have a value of "value1", the program should click that button. This should be done with a for loop.. but like I said, I'm not sure how to accomplish this.
1- Read an Excel Worksheet into DataTable (dt);2- Check 'dt' to know if some columns titles exists;3- Query 'dt' and discard rows where some itens are null or empty;4- After query 'dt', fill some ComboBox.I wrote the code below. It works nice, but I don't know if I'm using best practices when I use Linq to query the data table like I did.

I'm working on a college VB project using an 2D array with 2 combo boxes. One combo box selects a size and the other selects a style. I have everything working correctly with calculations except I need each combo box to pop up a message box if the user doesn't make a selection in a combo box. It will pop up for one combo box, but not the other. My question is how do I get the program to pop up a message box for each combo box independently? Should I use Try/Catch or would another method work better? (I'm using VB Studio 2010)

Now i called this function on the button click of my login form and passed the values of username and password textboxes as parameters to it. But the problem arising is that it is logging in by simply clicking the button irrespective of what is entered in the username and password textboxes.
I think this is because ds.Tables.Count is never 0(whether the username and password match or not) Use code tags when posting your code. Code tags are used like so =>
I am trying to do a form it has 2 comboboxes and I have the arrays set up one of the combboxes is for pizza size and it has 4 selections and the other combobox is for crust style it has 2 selections. The user has to pick on of each and it pills the price from the array and then displays the price in a text box. I for the life of me can't figure out how to get it to pull the info from the array and then display it in the text box, it either displays nothing in the text box or a 0 or 1.
