Multiple Forms - Quickly Opening All Tabs?
May 11, 2010
I'm just having a small problem with tabpages. I have a program that have multiple forms (on startup they are all created and hidden, except for the one being viewed by the user). When the user open one particular form, I has a tab control with two pages. I also have a toolbar. when the user click a menu option, I call a method that assigns all my controls to a variable (to be used in an insert statement later).
Here's an example of that Sub:
Public Sub SetValues()
'page 1
DateCreated = Date.Now
DateEdited = Date.Now
DateCompleted = Me.DateTimePicker2.Text
[Code] .....
The problem is, the controls on the second page cant be "seen" (this is confirmed by placing a msgbox in the above sub, which comes up blank) until the user open the second tab, at least just once. Then its ok. I know I can just run a small method to quickly open all tabs, but is there a reason this is happening, and a better way to do this?

Over the past months I have been working on small windows forms applications and learning vb as i go along. The aim was to pull these altogether into one big application.
I am now at the stage of pulling these together I have created a new project (called MainMenu) and designed all the buttons and interface. I have added my other projects (SISApp, CURApp) to this project. File > Add > Existing Project. I can see these projects in the solution explorer.
Now my problem. How can show Form2 in the SISApp project when I click ButtonX in the MainMenu project.
I dont just want to show Form2, i want all the functionality and the database connection in form2 to also work etc.

I have a program that will let you open a certain table in the database and query it on a child form in a MDI parent form. Of course the child form is a new instance of an existing form.The thing I want to do is that the opened table in the child form cannot be reopened again in the other child form. So I did was to create a childform name on every new instance of a childform depending what is the name of the table.
The first thing I did to do this restriction is to put the names of the opened table to an public array and when the user tried to reopen the table, the program will check if the childform name is already existing... and if it exist it will not let the user to open the table in new childform.When the childform is close it will erase it's name to the public array. And it can be open again.If you don't understand what I want to do this is the situation for example in a microsoft office when a word document file was open it will be put in a childform, and when the user tried to open the word file again and still the word file is open in the microsoft word the application will tell it's user that the word document file is still open.

I am running Microsoft Visual Basic 2010 Express. I created a simple program that is nothing more than dozens of Windows Forms that are linked together by the various clickable buttons I put on each form. The program is like a "book" with several pages, and you jump to a specific page by clicking on specific buttons on the current page ("Windows Form").
My question is, how do I change my program so that when it is launched, instead of just 1 Windows Form opening, the program opens up several Windows Forms (of my choosing) automatically? In other words, instead of my "book" (VB program) opening "page 1," when I run it, I want it so that pages 4, 7, 8, 10, and 15, are "opened" whenever I run my "book."
Is there some code I need to insert into each Windows Form I wanted opened automatically when the program is loaded? Or is this a MS VB 2010 Express environment option I need to set?

Starting to design an application and wondering if its ok to have only one form as the application which could hold up to 15 gridviews separated in tabs etc. with a navbar as navigation on the left. Is this too much or ok? Is it better to have one gridview per form? What is the norm?

i am building a tab control (using VS 2010 and 4.0 framework). on Tab 0, this works as expected:
Me.ddUE_B1.SelectedValue = Me.B1.Text <-- changes the combo box selection to what is in the label.
on the other tabs this does not work. when I do a messagebox to show, say, Me.Ea1.Text on Tab 1, nothing is returned.
Is there an issue with referencing controls on tabs that I am missing? In general, I will need to set combo box's value to what is in the database when the form loads.

I use VB. NET 2008. I'm starting to work with the Tab Control and command will want to know about techniques such as adding tabs at runtime using this control.
To illustrate what I'm saying, just take one checked on your browser or in the VB (Start Page, when we add other forms to our project).

Using vb.net 2008 Forms. I have a groupbox consisting of several textbox's and a push button. I put this groupbox in a control collection in order to validate each texbox when the push button is clicked.
The code to do this is as follows:
Private Sub bn_updateadditem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bn_updateadditem.Click
Dim InvalidInput As Boolean = False
Controls.AddRange(New System.Windows.Forms.Control() {Me.GroupBox1})
Dim ctrl As Control
For Each ctrl In Controls
[Code] .....
This worked great. However when I moved this groupbox with all its controls onto a tab, the groupbox contents disappeared from the form after the control collection is created and contents validated (per above code).

I have a tab (created in the form developer) that contains about a dozen controls. I need to be able to clone this tab w/all controls. I have no problem creating the forms. However, the controls don't copy. This is true whether I create the new tab with a string:
TabPages.Add(MO.Name)Or with a tab object assigned to the base form:
Dim NewTab As New TabPage
NewTab = MyBaseTabPage
TabPages.Add(NewTab)
In either case, my first tab has everything it should have the other tabs have, the other tabs have only the tab name.Basically, I want to be able to clone my base tab into n number of tabs.

I've got a tab control and want to dynamically add tabs depending on the output from a database. I can easily add a new tab, however I want to inherit the controls and layout from the initial tab.

I was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?

My code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.

Since last 2 days I have been getting a strange problem with my Vb programming (VS2005). Whenever I open any Vb or C# code and press F5 (in order to debug), several windows open at a time like Memory1, Memory2, Memory3, Threads, Processes, Registers, Data sources. And simultaneously the SOLUTION EXPLORER that is present at top-leftmost corner generally goes missing. When I restore that and put my cursor over SOLUTION EXPLORER, the program hangs and a message comes as : "Microsoft Visual Studio has encountered a problem and needs to close".I have attached the screen shots of the problems to this Thread.I tried various ways like restoring my computer to an early date, repairing Windows XP and then uninstalling and reinstalling Visual Studio. But none seem to work.

I am having a serious issue with Visual Studio 2005. Whenever I open any Vb or C# app and press F5(to debug), multiple windows open simultaneously like Memory1, Memory2, Threads, Processes, etc... Also, SOLUTION EXPLORER goes missing from top-leftmost area(where it is present usually). When I put the cursor over SOLUTION EXPLORER (after restoring it), the program hangs and the following message is displayed: "Microsoft Visual Studio has encountered a problem and needs to close".
There is no option to attach something, otherwise I would have attached the screenshots of the problems.

I'm writing a program which gets the time and date from forums which only show "x hours ago" on the main thread list.What I do is get a list of threads, open their print version and fetch the info.I'm currently using a single webbrowser, because there's no control array anymore. This makes the proccess very slow.Is there a way to open all the threads' print versions simultaneously?(BTW, I'm using DOM functions like GetElementsByTag, so I'll need to get the page's "Document" object.)

I have made a registry entry as follows: HKEY_CLASSES_ROOTMy AppShellOpenCommandAnd gave it the value: "C:Program Filesmyapp.exe" "%1" "%2"I also had a drophandler to for the apphis entry works fine for opening one file that is dragged to my app's icon. The problem is that I can only drag one file at a time into the app. If I try to drag more, it only ees the first file and ignores the others. I use the My.Application.CommandLineArgs array to access the command arguments. For example, My.Application.CommandLineArgs.Item(1) will open the file. If I change the registry entry to:"C:Program Filesmyapp.exe" "%1" "%2" "%3"This will open the first two files, but ignore the rest. If I change the registry entry to "C:Program Filesmyapp.exe" "%1" "%2" "%3" "%4"This will have the same behavior as the previous entry and ignore all but the first two files.

I'm implementing a poor-man's ORM an a legacy application (.NET 2.0 web app, hand-coded SQL queries). I have two data classes: Customer and Order:
Public Class Customer
Public Property CustomerId As Integer
Public Property CustomerName As String
[code]....
I'm concerned about the performance of this method, namely if I'm pulling multiple Customer's. For each Customer pulled, I have to hit the database again (opening another connection), and getting the orders for that given customer. If I'm not mistaking, it wouldn't take many records to accumulate a large number of open connections.
How can I determine the number of new connections being made and whether or not I'll encounter any connection pooling or other such .NET-imposed limits?
One thought I've had is to pass the SQLConnection object created in the calling class to the getOrdersByCustomerId function and have that function use the (apparently?) already-open connection. I have not tested it namely because I don't know how to determine if it's better than my existing method. Thoughts?
I'm creating a search web service that returns JSON for processing by the client. The service takes a single search parameter, performs multiple lookups on different tables, then returns a custom JSON object. For example, if the user puts in what appears to be a name, I search both the Customers table for a list of the top n customers and the Orders table for the top n orders that have a customer with that name.

Firstly though, I'll have to mention that I'm a relative newcomer to vb.net and don't really know that much about advanced functions.I have my main form which dynamically generates 15 buttons.
Each of these buttons will need to open another form, depending on which form has been assigned to that button in a config file (the config file isn't yet done, as I want to get it working simply by hardcoding the name of the forms for the time being)
The way I have it in my head is that I would assign the form name that needs to be open to the name of the button, if that makes sense....However, I have absolutely no clue how to do it, I've tried a couple of things but to no avail.
Here's my code, and I have no problem changing any part of it if it will help things along, this is just the only way I know how to create dynamic buttons.[CODE...]

I want to open a VB.net form using a ThreadPool with a maximum of 10 threads. I need to do this because, the form should open based on a live event and i need atmost 10 forms on the desktop at a time. If i open the form on every live event without using a ThreadPool, the desktop will be floaded with many forms. I am using QueueUserWorkItem method of threadpool to queue a method which opens the form. In this queued method, there is form1.show() statement called. But after displaying the form, this method finishes execution and again we have 10 threads available in the system. I somehow want to either keep this method running so that 1 thread is occupied or i want to keep the thread alive till the form1 is closed by the user. I want the 11th form to appear on the desktop, only when any of the existing forms out of the 10 (already on desktop) is closed.

I might be going about this the wrong way, but I'm trying to create a form that will include a single button, for instance "Enter". When "Enter" is clicked, I want the form to then display the contents of form 2, which might include more buttons and/or a textbox, etc. I want to do all this without ever opening or closing a form.
