Windows Forms MenuItem Displaying 2 Columns?
May 5, 2011
I am making a change to some code written in vb.net, its a winforms app. The menuitem uses the System.Windows.Forms.MenuItem control. I need to display the values in that drop down menu into 2 columns. It displays a number of items and therefore is too long.I wish to display the items side but side in 2 columns. In C# you can use ToolStripMenuItem which allows you to display multiple columns. Even though ToolStripMenuItem is available in Vb.net its difficult for me in the current app to switch to that tool.

I have a progress bar on a Windows Form which displays the number of records as they are retrieved from the database.The problem I'm having is that the entire Form.Load() method seems to run prior to the form being displayed, which means all my code updating the progress bar is gone to waste.

I try to create a MDI child form that should be resizable but it should not have a title bar visible. Is it possible? Or is there a better method to display child windows within a main form than displaying other forms. In this case the panel would be visually better than the form but the panel cannot be set to act as a child like a form.

I have an application written in VB.net, compiled and loaded on machines running XP, Vista and Server 2003. When I loaded it on a machine running Windows 7 64 bit, the application runs fine, but one window that has MenuItem controls does not work properly, instead of being able to change items from the collection, that area is just greyed. I loaded the .NET 4.0 framework on it in hopes of some miracle, but it still does not work.

I have a gallery which holds a large number of thumbnail images and I want to show 6 at a time.
I have this working using the code below, but I can not get the images to display as 2 rows of 3 - it shows as 6 rows of 1.
I can get the desired result by using a datalist but that stops the pageindex function from working.
I'm sure there's an easy solution but I can't figure it out.
<asp:GridView id="GridView1" runat="server" AutoGenerateColumns="False" AllowPaging="True" PageSize="6" onpageindexchanging="PageIndexChanged" PagerSettings-Mode="NextPrevious" PagerSettings-NextPageText="Next" PagerSettings-PreviousPageText="Previous">

This is a follow up to my previous question: Filter DirectoryInfo files by date in asp.net
I have a gridview that is populating data from DirectoryInfo. However, I only want to display certain columns, and customize the column names and the hyperlink value in the row.
My code is:
Dim files As FileInfo() = New DirectoryInfo(strDirectoryPath).GetFiles().Where(Function(x) x.LastWriteTime >= (dtStartDate) AndAlso x.LastWriteTime <= (dtEndDate)).ToArray()
[Code]....
How can I loop through the columns, to display only "name", "extension" and LastWriteTime?

I'm trying to write a jukebox application as part of my undergraduate coursework at university, and have hit a brick wall. Using while loops, I'm trying to display tracks/songs under particular genres, as listed in a simple text file, from which the programme reads.The issue is, although I can get the columns to be named after the appropriate genres, as stated in the text file, the songs are read, and placed in the first column, regardless. I can't seem to get them to move to the next column, when the previous genre is finished.[code]

I'm making a console game that shows some data:
#: Item Name Item Slot Cost Item Price
in that order. The thing I want to do is to make it come out in nice even columns...but I can't seem to make it do that. It comes it out in nasty uneven rows that don't look attractive...
Basically, here's what it looks like now:
1. Sword Slots: 2 Price: $40
2. W. Stick Slots: 4 Price: $1
I want to get each column to line up nicely with the other (since I control the size name).

I have created an application that uses two forms one is displayed on a touchscreen and is a basic input form, the other is displayed on a large display monitor and is basically an information form, both displays are connected to the same pc. The program works great I have just one annoyance is if the program is restarted it displays both forms on the touchscreen and I have to drag the information form onto the big display. Is there a way to specify on load that each form gets displayed maximized on a certain screen so I don't have to drag one form onto the correct screen?

I have a datepicker control that displays an appointment date. This date may be nothing, but the datepicker always displays a date, understandable I suppose.There a plenty of occasions when I want a date to be null, and to display that status, how is this commonly handled in the user interface? I don't want to give up the nice functionality of the datapicker, but I need to somehow indicate that no date has yet been set.

I have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer)
Dim sw As New Stopwatch
sw.Start()
Do While sw.ElapsedMilliseconds < interval
' Allows UI to remain responsive
Application.DoEvents()
Loop
sw.Stop()
End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.

I am having a problem with objects that have other objects as properties on a property grid. Now when I display the object clsPropsFrame on the property grid, everything shows up as expected, except when I try to edit the x, y, or z of location which is of type clsPropsVec3, it ignores the change. What's strange is that when I type the vector in as a string (like "0, 16, 0"), it changes.
I have the following
'//////////////////Object Component///////////////////////////
<TypeConverter(GetType(ExpandableObjectConverter))> _
Public Class clsPropsVec3
Inherits ExpandableObjectConverter
Private refvec As TV_3DVECTOR
Public Sub New()
[Code] .....
I noticed that when I changed a component of clsPropsVec3, the property change in clsPropsFrame does not get executed. I tried making it fire of an event when a component is changed in clsPropsVec3, with the following additional
Public Property X() As Single
Get
Return refvec.x
End Get
Set(ByVal value As Single)
[Code] .....
But for some reason it ever fires off the ValueChanged event. So how can I make the sub properties of clsPropsVec3 work?

I have a panel with some controls in it (several textboxes, a slider, 2 buttons, and a small groupbox).. When I click a button, I want all of the textboxes within the panel to be readonly... So I have this code: [code] When I run it though, I get the following error:Unable to cast object of type 'System.Windows.Forms.Button' to type 'System.Windows.Forms.TextBox'.If I remove a button, it moves on to give me the same error but for a label..

I am running into the strangest problem that I just can't place my finger on. I've been developing an application in VB.net for the last couple months in Windows 7. The program involves some basic OpenGL drawing and animation with basic shapes (squares and circles) and basic textures mapped onto pointlists. The time has come to distribute the program to another machine. On some machines though, I encounter problems when I'm drawing textures. I know that openGL is still functional because drawing basic squares and circles still occur, the textured objects are the only things missing.

I am having some trouble with some data I want to display on a form. The data is in a 2-D array, call it myarray(x,y). My attempts to display it have so far not worked. Similarly, I also need to read this data from the form back into an array for further calculations.

I would like to display 2 forms side by side. Frm1 will call Frm2. The problem is, if Frm1 is too near the edge of the computer screen, when Fr2 is shown, part of it will be outside the screen. How do I make it so that if Frm1 is near the right-side of the screen then Frm2 will show on the left-side of Frm1 and vise-versa?

I want to read from a text file and display it in a label. However, when I do that, I see that there is no word wrapping. In the sense, a whole paragraph is displayed in one line and the next one in the next line and so on. Can some one please tell me how to read text from a file and make it display as it is (lines as they are)? I am using the following code right now:
Imports Microsoft.Office.Tools.Word
Imports System.Runtime.InteropServices
Imports Microsoft.Office.Interop.Word

actually i'm trying to write a small program for my project's presentation. i created a form with buttons, each time i click on a button, i want a text loaded from MS word document to be displayed inside the form.
i thought about dislaying the text inside a label or textbox, but the problem is that the text doesn't preserve its state, i mean colors and fonts which are defined in the MS word document, it just displays everything in black color, small size..etc, even if i change the properties of the label in color or font, thoses changes will be applied to the whole text.
is there any control who can display the text loaded from a MS word coument with its colors and fonts which are already defined in the word document, or there any solution to do this ?

Just moved a .NET 2.0 App from VS2005 to VS2010 and noticed that now when a window containing a WebBrowser tries to retrieve a pdf it thows out an error (unknown file type System.Byte[]). This would usually indicate that Acrobat Reader has not been installed - but open up IE9 and enter the link into the address bar and the PDF displays in the browser without any incident!
Should point out that the app created in VS2005 and installed on Win 7 (actually Server 2008 R2 in 'Workstation Mode') has the same issue.. All works fine in XP and below... Do seem to remember this on a Vista box, but put that down to Acrobat not being installed!

The functionality of the application is not that difficult. The challenge is in the displaying of the forms. I have not started coding yet. When I run the application, the screen should be in the land scape format irrelevant of which computer or laptop you are using and how costly it is. The form should be displayed 90 degrees rotated in counter clock wise direction. How is that possible? Attached is the screen shot of what I want.
