View 2 RepliesI am trying to update a Vs2008 project to vs2010. In one of my projects I have two controls. The controls are not being seen by the form when I open it up in design view. They are friend controls. (No code has changed since I opened it up in vs2010.) But it was running fine in vs2008.

View 13 RepliesI've been digging around but I can't seem to find anyway to adjust the volume controls (the windows general ones) using VB .NET.Basically, I want to make a program that's always on top that allows me to changemute the microphone and the other volume values on a specific device - not necessarily the one set as default.
I got this weird feeling that I'm missing something quite simple but I simply could not find anything. I saw some media players and such but nothing similar to what I was looking for.
I have this VB.Net form and I need to know the names of all the controls on it. I would suppose that Microsoft keeps a list of all the controls on any given form I just don't know how to access it.
View 4 RepliesI am editing an application that was developed using VB .NET. The form has a button, I see it in the code but it is not visible in the Form. Also, when I place a new button, it comes as Button2 meaning there is a Button1 - I am not sure how to find where it is and place it at the right place.

View 2 RepliesI have a group of controls dynamically added to a forms with a name like "OptionID_#" where the "#" is unique number.1st I need to check if these controls are checked/unchecked, but am having a difficult time even finding them to make that first check.I thought controls.find might work, but Controls.Find ("Option ID_" True) dues not seem to find my controls.2nd I need to get the "#" from each of those checked options.I think that Split(conControl.Name, "_") should work to get me two different parts one with the OptionID, and the other with the "#".Still stuck on the first part though of actuall locating the controls I need.

View 2 RepliesI have a form with many buttons on it and I would like to loop through all the controls in a group control and find out which button is clicked.
I plan to use the click event of the button and I know it's easy to create a click event procedure for all of the buttons but would like to avoid that.
The group control is called GroupFilterButtons.
1. i added a datagrid at runtime on a form. i want to bind a datasource to the datagrid in a button's click event handler, but the datagrid doesn't seem to be visible anywhere else outside the form load event where it is declared. how can i find the datagrid control?

I have been writing VBA code for MS Access for years, but am starting my first project that will need to retrieve data from the Internet. I have come across code samples that use "Microsoft Internet Controls" and "Microsoft HTML Object Library", and I can make them available references in VBA, and available methods and fields etc. show when writing code, but I cannot find any documentation for these APIs. Does it come with MS Office on the CDs (if so, where?), or is it available over the Internet somewhere?

There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

If I have the following ListView, how can I attach a SelectedIndexChanged event listener to the DropDownList so I can perform a command on the respective object? Imagine I have a list of new users and I want to add them to a usergroup by selecting the group from the DropDownList.

I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?
I've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.
There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.

I've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out. After all this time I remembered about it again.If I create a usercontrol/containercontrol and add one or more controls to the controls surface, I just cannot figure out how to access the controls at design time.

View 2 RepliesI have a query about dynamically added controls to a form. I have a series of buttons which are created and added at run time. I have a two drop down lists and two buttons which are created at design time. Button 1 creates a series of buttons called "Test 1.x" based upon the selection of the two drop down lists. This works fine and am happy with the logic.However.... Button two should remove all the dynamically created buttons from the form.This does not happen. What does happen is that 50% of the buttons are removed starting with the first one. WHen checking the loop it only enters the loop half the amount of times that there are buttons. Very strange. When the loop is run repeatability it will remove all controls. Why will my logic not remove all the dynamically created controls at once? What is wrong with my logic?
I attach two code snippets and the .net file for your consideration.Button method which creates the dynamically created buttons from the two drop down lists and adds to form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

View 4 RepliesI have aspx form with several textboxes.They are populated with values from a table via retrieval of a dataview.If the row count for the dataview is 0, then I'd like to reset the values in all textboxes. How can I loop through all the textboxes and set a default value?I've tried the following, but no sucess.
For Each ctrl As Control In Page.Form.Controls
If TypeOf ctrl Is WebControls.TextBox Then
CType(ctrl, WebControls.TextBox).Text = ""
End If
Next
My first For Loop was using Page.Controls but it returned only 1 count.The textboxes are inside a tabpanel (ajax), so do I have to locate the tabpage and then find all it's controls (for each tabpage)?
I am currently using the code below within a VB.Net application to find specific text in a Word document. The text is surrounded by symbols represented by the character codes in the .Text statement. The code below is working fine. The issue now is that sometimes the desired text within a document has been marked for deletion and appears as tracked change within the document. I would like to find only the desired text that has NOT been marked for deletion. Does anyone know of a way to determine if the found text is a deletion?

How can I add controls to a form in code and set the properties of the controls using the With statement?Also I would like to know how to add a container control and then add a control to that container.
View 2 RepliesI have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
