I am using VBNET2008 to develop a Application using FORM and the Logic using FOR LOOP. Within FOR LOOP logic to fill the Form TextBox from DataSet and also to Fill ProgressBar Progress. Apparently Within the FOR LOOP the FORM TextBox and ProgressBar1 is not filled.
Here are the overall Coding
Private Sub FCountTotalOrderID()
'--- retrieve OrderID Row count from Table ---
Dim strsql As String
[Code].....
I was able to make my progress bar transparent, and I have a textbox, I want to see what's in the textbox behind the progress bar, but the progress bar it's not not showing it.
ProgressBar1.BackColor = Me.BackColor
me.backcolor = transparent
how to load data into datagridview using backgroundworker & progressbar?Let's say i have a report that shows some statistics, or has 100 000 of rows that should be displayed and during the load i would like to show the data that is already loaded and not to frees the form.Same example like in SQL when you perform a select command from a table which has 100 000 of rows and while loading the data, the grid is already filled up and progressbar is shown at the left buttom side.

I have checked out the webpage manipulation on VBForums but it did not help me in this case because this textbox is not part of a form.Okay so basically i need to be able to add text to the textbox where you type in your bid on eBay and then send the enter key to submit the form that i can't see (so just the enter key)
View 5 RepliesI am making a Help-form for my application. A Help-form normally has a ListView on the left and a RichTextbox on the right. When you click on a Help topic in the ListView, the text in the RichTextbox is supposed to change accordingly. The text file is part of the application's resources.

I am using a SQL query to fill a datatable from 2 associated tables. The first table has Products and the second has associated addonpackages. When I loop through my Products I am able to get all of the addonpackages for the first product but after that the datatable is only getting populated with the last addonpackage for each product. ie:
product 1 - all 6 packages are added tp the datatable
product 2 - only package 6 is added to the datatable
product 3 - only package 6 is added to the datatable
...and so on
My query follows. Why I am getting all of the info for the first product but just the last item for all others. No matter which product I would query first, I get all of the associated data with it but only the last for all others.
SELECT Products.ProductNumber, Products.Name, Products.Mnemonic, AddOnPackages.PackageNumber,
AddOnPackages.Name AS PackName, AddOnPackages.Mnemonic AS PackMnem
FROM AddOnPackages RIGHT OUTER JOIN
Products ON AddOnPackages.ProductNumber = Products.ProductNumber
WHERE (Products.Name = @ProdName)
ORDER BY Products.ProductNumber, AddOnPackages.PackageNumber
I am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?
To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?
this is my code
Dim str As String = "str1,str2"
Dim array() As String = str.Split(",")
Dim MyListOfTextBoxes() As TextBox = {TextBox1, TextBox2, TextBox3}
[Code]....
i have 5 textboxes. i want to fill just textbox1 and textbox2 with array value. because no i have to word.but when i run the code "str1" repetition on textbox1,textbox2 and textbox3.
I have a series of checkboxes named cbS1 through cbS20 and I set 'Count' as an integer.What I need help doing is taking the value of count and check the checkboxes that are greater than the count.example: count = 7 so checkboxes 8-20 would be checked.Im not sure how to make an array out of the checkboxes to use in a loop.
View 1 RepliesI have an Access 07 database I'm using to store my data. I have no problem at all filling a worksheet in excel or a table in word from the textboxes currently on the screen and saving it as a pdf. That's basically how I'm reporting my data from my program.
Where I'm stuck is how can I do the same process for each row in my dataset that has a date or value similar to a filter? I can filter the dataset by adding a query in the dataset designer so it only displays the rows I want to build form reports for, but I don't know how to code a loop to make it work for each row.
Basically I'm looking to find a way to print and/or create pdf form from one button click for multiple records and not just the one currently bound on the screen.
I am making this program that has a loop that goes to a website and fills in a form within the loop. But first, here is my code thus far
Dim message As String = TextBox3.Text
Dim loopnumber As Integer = TextBox4.Text 'makes the necessary variables
Dim browser As New WebBrowser
Dim url As String
[Code] .....
But what happens is that the loop runs a few times then it errors on the setattribute line (line 19 above) with
NullRefrenceException was unhandled
And I have a feeling that it is not loading the page fully before it tries to fill in the form.
I have a sub that i wrote only to temporarily fill the database in during run time to be able to test a few other functions that i wrote as well ... weird thing is by the way i wrote it it should only look 100 times... but by the unique ID in the database and the information it pulls back into my list box it loops 700 times before actually stopping the loop ...
Public Sub Fill_LeftOvers()
Dim x As Integer = 0
conn.Open()
[CODE]...
Now i used step debugging and sure enough it only loops 100 times during stepping but in the database it looped like crazy ... i have also tried while x < 100 instead of the do loop but it did the same thing ... i know this may be considered a double post i mistakenly posted originally in the PHP forums earlier today ...
How would you verify a textbox if contains at least one numeric digit and one alpha character using loop?
View 3 RepliesI've got Visual Studio 2010 and I am looking to clean up my code technique, since I've taught myself and now I'm taking classes.
I'm trying to use a For...Next Loop so that I can fill a text box with sequential numbers. For some reason, all I can get in the text box is the last number and I feel that at this point I'm probably overthinking it...
All I want is on the button push the text box shows:

I am using a select case loop to perform different tasks, one of the tasks the loop is doing is putting 1d arrays together into 3d arrays. But, when i come to print the 3d array only the 3rd "line" in the array is complete. Is there a way to pass variables created in a select case out of the select case?
Here is some code to try and explain better:
Select Case Int()
Case Is = 13

I recently finish my Microsoft VB.net training and learning something about delegates. I have two delegates in a excel source to control a progressbar and a text box on the mainform
Public Delegate Sub ReportProgres(ByVal percent As Integer)
Public Delegate Sub ReportText(ByVal Mytxt As String)
I want to use these delegates in a second excel source also. It gives declared in the first excel file and two conflict errors in namespace windows application.

View 3 RepliesI don�t want to use built-in data binding through Visual Studio, I would like to learn and code directly. I have created a form with a listbox on the left side and several texbox on the right side. I have code working that populates a listbox from my data reader (MyReader). The listbox works fine. There are two (2) buttons over the listbox to select All Active records or All Inactive records that queries the field �Status� in the �tblAdvocates� table.So the listbox works fine. Problem is trying to setup the SelectedIndexChanged function. I can�t figure out how to take the selected record from the listbox and use that to fill the textboxes. Do I �re-query� the database using the ID field from the table? Do I use the MyReader from the form load code and pull the data from that?
Here is my code:

Imports System.Windows.Forms.ListBox

Well, my problems is follow. I use a textbox where the user can enter a text but which I would like to prefill out with a variable (later , with more experience, want to ask the AD for the username and put it in the box).
That means, when the user runs the app, automatically is the username written in the textbox without pushing a button but the user has the opportunity to change it (For example doesnt want the second surname).
