I have a desktop application by which i have to send mail to multiple recipients. There is a grid view in a form. There are some customer list in the grid view and for each row there will be a check box. User can check or uncheck the check boxes. Also there is a send button. when user click on the send button then a mail will be sent to those customer whose check boxes are checked.

I can propagate string values, but not the status of check boxes. code is like this UpdateForm.chkboxincomplete.CheckState = dgridview1.Rows(e.RowIndex).Cells(3).xxxxxxxxxx i need to know what to put for xxxxxxx or any other method to do this task.

i am trying to automatically generate multiple text boxes on a form with the following code
Private Sub CreateTB(ByVal x As Integer)
Dim y As Integer = 1
Do Until y = x
[Code]...
i need it to generate as many text boxes as the variable x states, so i used the do until loop thing. But i am stuck when it comes to naming the text boxes because obviously all the text boxes cannot share the same name. so i would like to know how to programmatically name each textbox uniquely.

View 6 RepliesSo as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I use check boxes and place them on my user interface (See attachment)I have coded the code for "select all" button :
Code:
Private Sub checkedall_Click(ByVal sender As System.Object, ByVal e As_
System.EventArgs) Handles checkedall.Click
Dim chkboxes, outs As New Collection()
[code]....
I could not seems to check all the boxes. Is there something wrong with it? I am not sure how to assign array to check boxes.
I have actually two list boxes and grid view.The grid view has three coloumns fields.Now i want to customize the grid view with the list box. Suppose the fields are employeename,employee id,employee code. The left list box contains all the three fields namely employeename,employee id,employee code.There is an add button fixed so that on adding the selected row moves to right list box;the moved row gets removed from left list box.Now left list box has only rows employee name and employee id.Whereas right list box has employee code.Now when user hits Ok button the rows in the right list box are only highlighted.

I have a FlexGrid control in my Windows application that contains a row of data. The data in this row is related to even more data that won't all fit on the same row. For Example:The main data row contains Username, Last Name, First Name, Middle Name, E-mail Address, Phone Number, etcA secondary row to this might contain user permissions to certain resources, such as File Server Access, FTP Access, Remote Access, etc.Now, I can use the subtotal and outline capabilities of the VSFlexGrid to make a second row, but the column widths are still bound by those set for the main data row. Additionally, I can't put real "headers" on the supplemental data. I have to fake it by creating an additional row, setting the background color of that row to gray, putting the header strings into those fields, and then adding the next row with the actual details.
What I would like to do is create separate grids for these secondary rows and "embed" them in a blank row of the existing FlexGrid control directly under the related main data row. This would give me the ability to use a different number of columns, to format these columns independently of the "parent" FlexGrid settings, as well as put a new header row for the new grid that identifies its data.In other words, I'd like to somehow make a "child" grid that's related to a particular row of the "parent" grid (not the entire grid itself). I don't know if this is possible, and if there is another way for me to accomplish this goal, I'm all ears. However, if it IS possible, I'd love some advice on how to implement it.
I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.

The Object Browser does not seem to help - am I reading it wrong?
View 14 RepliesIf I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

I've got a screen with 4 group box and several text box inside them.Each group box is controlled by a check box, so if the check box is true, the group box is enabled. Otherwise, the group box will be disabled.So far, I've been using a 'Refresh' button to evaluate the check boxes values.Now I'd like to give up using that button, so if when I change the check box state, so will do the group box. How could I do that?

View 2 RepliesUsing Studio/VB 2010 here and would like to find out how to approach the following. Examples would also be welcomed as I've not yet tried the progress bar control.
Scenario: A windows form will contain multiple check box controls that will be "auto-checked" as other parts of the user application/interface are completed. I would like to show a progress bar on the form that will give the viewer some idea of what has been completed. For example, 5 of 20 checked-off would show 25% in the progress bar.
I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
I was thinking of checking the registry keys that a web browsers makes, and hopefully seeing if I could get accurate answer. Yet I only discovered that most of them do not remove registry values after a uninstall, nor do they make any indication that the program was removed from the system.
View 6 RepliesI'm attempting to write an app that watching for process spikes. IE: Watch every active process and log the difference between initial and max values of cpu percentage (or load) of each process. The problem is that, as far as I can tell from the MSDN, the Process class doesn't contain any property that is even remotely equal to the true load of the process. For the time being I've written the code to watch the PagedMemorySize64 property, but the values that are being spit out appear to have no relevance to load.
To be clear, I don't need the actual load percentage (though it would be handy), all I need is a property that is directly related to load to show what processes 'spike' during the execution of my program.
My code as it stands (initialProcessCheck runs first, then processCheck runs every 1.5 seconds or so until other threads doing irrelavent tasks are finished, then computeDeltas is run):
Private Sub initialProcessCheck()
'Checks the current load on all active processes and stores as initial values
For Each intPID As Integer In ActiveProcessIDs
Dim CheckProcess As Process = Process.GetProcessById(intPID)
