How To Enable Environment To Allow To View Controls On Different Tabs
May 22, 2009
I am about dead certain that in VB Express 2008 that I was able to have multiple tabs. And, on each tab I put controls. I could also click on a tab and see the controls only on that tab.I am now in Visual Studio Pro and I cannot for the life of me look at what is on a specific tab. Only the first tab wants to shows its controls.Does anyone know how to enable the environment to allow me to view the controls on different tabs?!

I am working on a project that requires the use of multiple tabs, but the problem is all my codes/layouts so far has been on a single form. How easy would it be to transfer the existing codes and layouts on a single form to a multi-tabs environment ?

I am trying to put in scripts for google analytics in my code. But I want it to run only if the environment is production and not in dev or qa. This javascript runs at page load itself and I am confused how to make it run conditionally. My app is an asp.net app.
Javascript is always confusing to me. There are many other javascripts in the page and I just need to disable this one. Had it been a .net code/function I would check for the environment and conditionally run the function. But I am confused about how to accomplish this type of functionality with javascript

It's kinda overkill (i7, 8GB, SDD, W7 x64) for what I actually need but it is supposed to last for a few years.For maintenance issues I had to install Visual Studio 2005 and it turns out that "Edit and Continue" wasn't working . I found a thread here HTML Code:[URL] in which I read that E&C is not supported in 64-bit OS.

Using VB.NET 08 I'm using the following code which loops through a datagridview and makes the buttons found in the list visible
HTML Code:CallByName(Me.Controls("btn_" & list.Rows(J).Cells(1).Value()), "Visible", CallType.Set, True)
This code works fine with no issue with the buttons on on the form. However when I placed the buttons in to a tabcontrol on the same form I get the following error:Object variable or With block variable not set.
Does this error relate to the way CallByName calls the button handler and that its different to they way you could otherwise produce the same result using
HTML Code:
button1.visible=true

I need to be able to programmatically create new tabs on a TabControl, add controls to them, and be able to update the controls in each tab from another function. I already have a function to add tabs to the control, and to add controls to those tabs when they are created, but I'm stuck as to update the controls after they have been created.EDIT: This is what I have to make the tabs and add the controls:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tabpage As New TabPage
tabpage.Text = "(empty)"
[code]....
I can't seem to get back into the account I used to post this question, so I have to post my follow-up to Tim's question in the comments for the previous answer as a new answer.Debug.WriteLine(TabControl1.TabPages.Item(2).Controls.Find("textbox1", True).Count) returns 0. The tab and the controls have been created prior.

I have a form that has many tabs and I have some buttons just bellow the tabs, but if I could move those buttons and place them inside the tab I would save some space bellow and I could extend on the tabs. So is there a way of moving controls from one tab to another depending which one has focus.

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.
<asp:ListView ID="NewUsers" runat="server" DataSourceID="NewUsersSDS" DataKeyNames="ID">
<LayoutTemplate>

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 have a form with a TabControl on it. On the first tab I have a DataGridView and I have a series of controls to represent six separate filters that can be applied to the data in the DataGridView. Each of these filters consists of 1. a ComboBox to display the columns in the DGV so the user can select one to filter on2. a ComboBox to contain the different filter conditions ("Equal to", "Greater Than", etc...)3. a TextBox to allow the user to enter the string to filter againstSo that's what's on the first tab. Tabs 2,3, and 4 are visually identical to tab 1 although they will hold different data and have different capabilities.

How would I code it so that I can use a random to add the number of the control so that a random control will be enabled. I.E. I'm trying to make a duck shooting game, random will get a random number then append that number to "picturebox" so that it becomes "picturebox36" to "picturebox70". Then I wall use that string along with ".enabled = true" in order to enable it.
So far I have this:
Public Class Form1
Dim RandomA As New Random
Dim rnd As New Integer

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 m implementing control based security in my application. where i m saving controlname (per form) in database, which are to be restricted. So far I have implemented the security and restricted control get disabled.
Now what i want to do is that i have to prevent that for those controls the "control.Enable" property should not change. how can i restrict that.
I have achieved the functionality by canceling enable=true property in "Invalidated" event of the control. but this is not some generic way. I have to map this event for all controls in all forms :(.
What i really want is that as all my froms are derived from same parent which implements the security. so the parent should some how restrict enable property from changing.
So,HOW CAN I PREVENT CONTROL enable property from changing in their parent class?

I am trying to use (and this may be my problem already) e.Graphics.CopyFromScreen() in the OnPaint() method of my control to prepare a background onto which I can draw the content of the control. The goal is a tool-tip with rounded corners and other specific features to replace the default Windows tool tip.
Ideally the tool tip could be antialiased and blended into the backdrop, however at a pinch I could tolerate an aliased boundary. This may also be necessary as the control will often be covering a control with an OpenGL overlay and the whole blending procedure may end up a nightmare.
I have created a custom user control, a persistent instance of which belonds to my applications's main form, overriding the OnPaint and OnPaintBackground methods. The application of transparency however is challenging. As I understand, the graphics object passed to the paint method starts with a copy of the current VisibleClipBounds, where generally the first move is to clear the control with a solid colour and start drawing the main features. My first thought was to bypass the fill and start drawing on the captured background. For the first redraw this works fine, but subsequent redraws keep the previous content instead of re-capturing the backdrop. I hoped that CopyFromScreen would specifically eliminate the currently drawing control from its capture so as to start from a clean base but this is not the case, it captures the rectangle of the new location including the image of the previous location if it is in the bounds.

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.

I have to turn this program in TOMORROW! I can't seem to figure out how to do this section. If someone I can do the second part.I have two text files, one is a single dimensional array, and one is a two dimensional array. One titled "Months.txt" and the other "Rain.txt".The problem is I have to read those into an array, and then after that, use a query to pull the information and display it into a data grid view style box.The problem I'm facing is when I pull the "Months.txt" text file, which has the months in order from January....December, and try to display it in the data grid it puts the length of the names of the months, not the actual months. me on this matter? I've tried to no avail. Also, how would you add all of the numbers in a single row of a two-dimensional array to give a total to display in the data grid? Also, the column?

I have a vb application ive been working on and its pretty much complete. I posted in the asp section but we couldn't get it figured out there so im reverting back to vb so looking for some help.I have a vb.net app I created and I have an internet browser embedded in it calling an asp page. the asp page is just a simple file that searches an access database. I used the asp page because I wanted to display the results with graphics and tables so I used html for that.Everything technically works except I am running it on a local intranet and the asp file is located on a server that is REALLY slow so it is taking 20-30 seconds to get my results. so, my question is, Are there any other options or ways I can do the search within the vb app itself so everything stays local and I don't have any speed issues. I can't install IIS on the local computer because the IT department is strict unfortunately.I don't HAVE to use "html" but I would like it to look nice with graphics and html was the only way I knew how to do that.

I'm trying to fill a ListView control in a VB2005 project. It works fine from underpinning (Access) database IF all the data is present. However, if a field is blank (in this case - a field called "Actual Date" which is meant to be blank for this record), the ListView will stop populating at that point.I thought this may have been the 'CausesValidation' property of the ListView but that doesn't seem to change the behaviour.Is this an inherent feature of the ListView - if so it seems daft - or is there a property I need to change or an override that I need to code?

figure out a way to link datagridviews to other controls like a combobox, list view or even another datagridviewBecause much of the code is managed by the IDE, I was expecting an IDE approach to linking controls. Is this the case or do I have to modify the generated code to do what I want.An example would be to use a combobox to limit the number of entries in a datagridview etc

i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.
