    - Is it possible to give a DataGridViewTextBoxColumn cell scroll bar I have a datagridview that is intended for read-only display (no editing whatsoever.) The problem is that one of the fields is bound to a SQL 2000 text field so it is potentially very large. At present I have the grid set up so that the text column has word wrap and displays everything. This might do but I think I can do better. What I would like to do is have rows of a fixed height, with individual text cells displaying scroll bars as necessary. Is this possible with the basic datagridview, or do I have to create a custom column control? Tag: Scrolling Menu Tag: 117793

Therefore I want to be able to block any attempt of closing app by user such as by clicking on close (cross) or Alt-F4 and once the app is finished doing what it is doing to close. In other words I need to close the app gracefully. How can I achieve this? Thanks Regards Tag: Scrolling Menu Tag: 117782

    - fill countries on image with color Hi all, Could the following be accomplished? I have a image of a map of the world as the background image of a form. The borders between countries are black lines. The countries have no fill colour, the are white. Dependent on some data about a countries I determine the fill colour of a country, say green. Is there a way I can specify a coordinate one my image and have the area (i.e. the country) in which that coordinate lies filled green? To make this work the area that is surrounded by black lines must be recognized by the software as a closed shape, which is not trivial I think. I have hopes that somewhere in .NET there is some pattern recognition algorithm that does this trick for me. Otherwise I probably will have to do a lot work defining all the countries explicitly as polygons,,,, Help would be very much appreciated!! Regards, Henk Tag: Scrolling Menu Tag: 117778

    - ClickOnce on Terminal Services farm Hello, We have a ClickOnce application that one of our clients would like to install in a Terminal Services server farm. The application is installed from a URL and added to the Start menu and uses the .NET 2.0 framework. The ClickOnce application files are stored in the directory C:\Documents and Settings\<username>\Local Settings\Application Data. The issue is that the Local Settings folder is not part of Profile Synchonization (or folder redirection). Their policy is that files in the Local Settings folder are removed when the user logs off. The result is that the application is re-installed each time the user runs the application from the start menu. This is of course unacceptable. I am afraid that the only solution is to have them use an MSI file, but I am looking for other ideas? I have read conflicting reports that there is a way to modify the ClickOnce store on each server? Anyone? Thanks in advance. Glenn Smith Tag: Scrolling Menu Tag: 117775

    - DataGridView question ... i'm hopeless I'm trying to automatically, using a timer, refresh a DataGridView (see attached code), but i don't succeed to display all rows correctly. I used both FirstDisplayedScrollingRowIndex as well CurrentCell but doesn't work (seeing all rows correctly). The delegate is only meant to call the MainLoop method after all rows are displayed.

    - URGENT * PLEASE - problem when sending mail - C# - Framework 1.1 Hey all, I have a URGENT problem and I hope someone could help me... scenery: I have a windows app, coded using C# (framework 1.1 - VS2003)... The exe and dlls of the app is are stored in a server, and the clients access this app through a shortcut that points to this. The folder of the app is shared on the network. This app accesses a oracle database. I'm using system.web.mail namespace.. The users/clients can access the app with no problem, everything ok. But when I try to send mails, I get an exception... When I'm debuging the app and running it local, the e-mail is sent, but when I copy it to the server and access the app through the network, i get the error... So here are my question: - What's the name given to this programming model (user/client accessing exes on a server)? - What are the requirements to accomplish this task according to this programming model? - Do the client pcs need something special to send the mail? Thanks for your help and sorry for poor english. Tag: Scrolling Menu Tag: 117756

    - DataGridView custom header row advice needed Hi I need to modify the header row of the DataGridView control. I don't want to change the current column headers but I need to add a kind of sub header row which will contain a couple of function buttons for changing the contents of a column. For example one of the column functions should allow a user to click a button which changes the values of all rows within a column to the value in the first cell. My question is what are my best options to allow for this? I have considered deriving from DataGridViewColumnHeaderCell but this seems a lot of work partly because I don't want to change the functionality of that type. I want to add a row underneath which is not data bound and always stays underneath the header row. I'm new to windows forms but have plenty of .net knowledge. I tried to find some examples/tutorials of modifying the DataGridView but have found very little. Any help or advice appreciated. Thanks Andrew Tag: Scrolling Menu Tag: 117751

Instead of it copying, I get an error message the the source file is in use. This happes regardless of whether I copy the file to another directory. I did change the name of the file and it copies fine. 1) why is the source file now in use by another program? 2) does the /z switch only work for the same session of robocopy?

    - who 'eats' my mouse click messages? Hi, I have a simple form with a simple button that does the following: static int button1Count = 0; void button1_Click(object sender, EventArgs e) { System.Diagnostics.Debug.WriteLine((button1Count++).ToString() +" Button1 - click"); System.Threading.Thread.Sleep(3000); System.Diagnostics.Debug.WriteLine("End Sleep"); } As you can see, when I click the button, it writes something to the output window and sleeps for 3 seconds. Then, it writes another line to the output window. Now, I do the following: I press 3 times quick enough that it takes less than 3 seconds. I notice that sometimes the button get pressed 3 times and sometimes, only twice. It looks like the messages are 'eaten' somehow... Can someone explain this? I tried to look for an explanation but failed to find such. Thanks in advance, Alon. Tag: Scrolling Menu Tag: 117748

Text boxes & labels, associated with some of the panels, only show up as outlines in the Design view. Their actual text is not displayed. What could cause this?

    - Images Do Not Show Up for TreeView Good afternoon. This had been working for several weeks, but something's changed and now my images are no longer visible in my TreeView! I've confirmed that the image file is in place and loaded correctly. I've confirmed that the ImageList is valid. I can reference imageList.Images[x] and access my icons just fine. However, if I add nodes to a TreeView and set their ImageIndex and SelectedImageIndex properties, I still see blank white. This persists whether the nodes are selected or not. It's not merely referencing the 0th element of the list, which had been blank white: for testing I made non-white. If the ImageList is valid, and the nodes' image indices are set, is there some obscure setting in TreeView that I need to enable display of images? Any ideas are appreciated! Code: ImageList imageList = new ImageList(); //imageList.ColorDepth = ColorDepth.Depth32Bit; // Has no effect imageList.ImageSize = new Size(20, 20); imageList.Images.AddStrip(global::MyNamespace.Properties.Resources.My_Icons); TreeTemp.ImageList = imageList; for (int j = 0; j < 4; j++) { TreeNode node = new TreeNode(j.ToString(), j, j); TreeTemp.Nodes.Add(node); // Show as blank white } TreeTemp.Invalidate(); // No effect BackgroundImage = imageList.Images[0]; // Displays test graphic as expected Tag: Scrolling Menu Tag: 117736

    - Drawing In my application I'm doing some drawing in my OnPaint routine using Graphics->DrawRectangle. The rect bounds are constant and not scaled in anyway. One of our Chinese customers is seeing the rectangles appear in the wrong place. When I started investigating this I found that I got the same problems if I changed my Windows DPI settings from 96 to 120. However the customer tells me that they are using 96 DPI. Are there any other settings which could cause this problem? They say it's the same whatever screen resolution they use. Also is there anyway to calculate the rectangle positions such that they will always be write no matter what the users Windows settings are? TIA, KK Tag: Scrolling Menu Tag: 117733

    - Odd query failure I'm writing a Winforms program in VB (Dot Net 2.0, VS2005) using a SQL Server 2000 database. I'm not sure whether I have a programming bug or a sql problem. I can't get a 'Like' query to work. I have a dll with an xsd. I dragged 2 fields from the Server Explorer onto the xsd. I then created a second query for a Like search. (I've probably used this basic technique hundreds of times on this job but I rarely use the 'Like' command.) This runs perfectly in the Query Builder. The query is as follows: SELECT serial, cnst FROM dbo.micro WHERE (serial LIKE @serial + '%') where 'serial' is the primary key, Char 11. 'cnst' is char 10 - null permitted. I have a data management layer which inherits the xsd. In that I created a pair of functions to fill the default 'micro' table: Public Sub FillMicro() Dim da As New DataManager.dsMicroScheduleTableAdapters.microTableAdapter Try da.Fill(micro) Catch ex As Exception MsgBox("Error Message") End Try End Sub Public Sub FillMicro(ByVal vsJobno As String) Dim da As New DataManager.dsMicroScheduleTableAdapters.microTableAdapter Try da.FillByLikeQuery(micro, vsJobno) Catch ex As Exception MsgBox("Error Message") End Try End Sub So, the first function FillMicro() works. The second, FillMicro(jobno) returns nothing, even though there should be about 1200 rows. I'm not getting any error messages or crashes. It just returns 0 rows. I'll probably find the bug 5 minutes after I post this but for now I'm stumped. Anyone see anything wrong with this? Tag: Scrolling Menu Tag: 117713

    - Can't remove highlighting when cursor is moved When I am editing code in VB.Net 2005 and I move my cursor, the code between where I was and where I now am stays highlighted.

    - Odd sizing problem I'm writing a Winforms app (Dot Net 2.0, VS2005, VB). I have a simple usercontrol with 2 panels on it, one with labels, one with a variety of editing controls, mostly datetimepickers and NumericUpDowns. A number of these usercontrols are then instantiated and put on a form in another project. The problem is this: The panel containing the controls is apparently expanding and increasing the space between controls, both height and width (so that part of it is hidden when the control displays). There is code that changes the width of the usercontrol itself and the position of the panel within the usercontrol, but no code whatever to change the width of the panel or height of anything. Autosize for the panel is False. What could I be forgetting? Tag: Scrolling Menu Tag: 117702

    - Custom form with its own designer / OnPaintAdornments (VS2008) Hi everybody, I have a form (inherits from Form) that has its proprietary title bar and and a footer section. I'd like to prevent the user from placing any control in those areas. That is, I'd like to define a deviating area on which controls may be placed. If i.e. a TableLayoutPanel is placed on the form and the Dock-property is set to "Fill", this needs to be the area that I define. I was assuming that it'd be sufficient to create a Designer that (just as with other controls) utilizes OnPaintAdornments to define/restrict the area where controls can be dropped. However, my designer is simply being ignored - none of the events there are being fired!? The scenario roughly looks like the following: --- 8< --- <ToolboxBitmap(GetType(Form)), Designer(GetType(My_Form_Designer))> _ Public Class MyForm Inherits System.Windows.Forms.Form '... End Class Public Class My_Form_Designer Inherits ParentControlDesigner '... Protected Overrides Sub OnPaintAdornments( _ ByVal pe As System.Windows.Forms.PaintEventArgs) MyBase.OnPaintAdornments(pe) '... End Sub End Class --- 8< --- The above designer's code should react if I add a messagebox-line and create a new form MyForm in a project. Unfortunately, nothing happens at all (no matter where I place a messagebox). Hence, is there any additional things one needs to implement in order to create a forms-designer? Any other base-designer I need to use or interfaces I would need to implement? Also, why would the behaviour of a forms-designer differ from that of other controls? I found many references on the web that were geared at control designers, but none of them explicitly addressed forms ...

When using a windows forms approach I can accomplish my goal - a portion of a window completely transparent so that it appears as though there is a "hole" in the application - I can do so in the following manner: 1 - Create Window, put Panel control on Window 2 - Set Window's TransparencyKey property to Pink 3 - Set Panel's background color to Pink This creates a see-through, "screen capture"-like look. There is, however, no TransparencyKey property on a WPF window. Is it possible to do this sort of thing in WPF? (I guess I could host a Windows Forms custom UserControl that does such a thing within a WPF window, but that seems a wee bit hoakie) Any advice appreciated! Tag: Scrolling Menu Tag: 117697

    - Winform sql server app Hi I am new to sql server and need to build a one-many winform app with visual studio 2008 and sql server backend and need some pointers. I have the following questions; 1. If I create the app by creating a relationship between master and child tables in dataset and then dragging the master table and relation onto a form to auto generate everything, would that be a good enough way to cerate the app? If so, what more can I do to turn it into a robust enough app such as error handling etc? If this is not a good way to cerate app what should I instead do? 2. Is there a good book on the subject of vs2008/vb2008 and sql server 2005 specifically, that will me sufficient advise on how to develop the app? Many Thanks Regards Tag: Scrolling Menu Tag: 117695

    - How to get text to fit inside a button Hi, I'm working with Visual Studio C# 2008 Express and I'm having the hardest time trying to get an 8.25f Microsoft Sans Serif font in a 70x18 pixel (width x height) FlatStyle.Popup button. The text just won't center to fit inside the button. The font gets chopped off at the bottom (because it doesn't want to perfectly center itself). Can someone else out there just try this to see what I mean? There's plenty of room in that button to fit that size text and it would save a lot of space in my app as I need several columns of these size buttons. It's just a Windows Forms App compiling to whatever Framework version Express defaults to (the latest, I presume). Thanks for the help! Tag: Scrolling Menu Tag: 117694

    - uncheck a checkboxcolumn in datagridview I've got a checkbox column in a datagrid view that I'd like to be able to validate, and if they've checked this column, but something else needs to be done first, I want to be able to backout and uncheck the column. How do I do that? Private Sub dgvDetail_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvDetail.CellContentClick With dgvDetail.CurrentCell Dim colIndex = .ColumnIndex If (.OwningColumn.DataPropertyName = "AccountingAcceptance") Then If (Convert.ToBoolean(.EditedFormattedValue) = True) Then If (dgvDetail.CurrentRow.Cells("txtNetPaymentAmount").Value.ToString.Length = 0) Then If (MsgBox("Do you wish for the Net Payment Amount to be updated with the value from the Check Amount?", MsgBoxStyle.YesNo, "Net Payment Amount Needed") = MsgBoxResult.Yes) Then dgvDetail.CurrentRow.Cells("txtNetPaymentAmount").Value = dgvDetail.CurrentRow.Cells("txtCheckAmount").Value Else ' uncheck it End If End If End If End If End With End Sub Tag: Scrolling Menu Tag: 117693

    - Interesting layout problem I have a rather interesting layout problem. At the moment I have a FlowLayoutPanel on a tab page. The size of the page may vary with the size of the window. The FlowLayoutPanel itself hosts a variable number of identically sized user controls. Autoscroll of the FLP is True. The idea, of course, is to smoothly fill the FLP horizontally no matter what the width of the FLP. So far, so good. Now I've been asked to change that. The powers that be want a left column of labels to match the individual controls on each of the user controls. (The controls of each usercontrol are arranged vertically.) I.e., if there were several rows of user controls, there would have to be a set of labels for each row. Even more interesting, they should stay parallel with their respective controls, no matter what the position of their row. In other words, they'd have to somehow stay in sync with their respective row while the user was scrolling the FLP up and down. Anyone ever do anything like this? (This is VB 2005.)

    - Storing form size To be user-friendly, I like to store the size and position of a window so that it can be opened in the same place the next time the user starts the app. Ideally, I would simply retrieve this information during the FormClosing event, but if the window is minimized at the time you get the minimized size and not the "restored" size. (The one thing I don't want to do is start the app minimized; it either opens at its last restored size or maximized.) Because of this I record the form's position and size during every Move or Resize event, but that seems clunky. Is there any way to ask (.NET framework method or API call, I don't care) a minimized window what its restored size and position are? Tag: Scrolling Menu Tag: 117681

    - Currency manager changes position on endedit Hi I have a winform app with fields bound to a backbend db via a currency manager (System.Windows.Forms.CurrencyManager). The app generally works fine but in a specific instance where I select a value from a drop down control and then call the MyCurrencyManager.EndCurrentEdit(), to begin to try to save the record, the position of the currency manger becomes -1 which creates problem in saving and accessing the original record. What could be the problem and how can I debug this? Many Thanks Regards Tag: Scrolling Menu Tag: 117675

    - Pausing a process without holding OS Hi I need to add pauses in-between processes in my app to give time to other users/processes on the network. Is there a way to pass control to OS for a specified time (say 15 seconds) to delay my app but at the same time not blocking OS's processor cycles? Thanks Regards Tag: Scrolling Menu Tag: 117673

    - Problem with forms MDI application I am building a MDI Windows Forms application where I have placed a splitcontiner. Using tabs I am trying to load different forms into the split container. Everything works fine, but for some reason the application hangs on exactly the 10th time a from is loaded into the splitcontainer (can repeat this). I have gone back to basics and removed all code from the child forms being loaded and still the applcaition hangs on the 10th time a form is loaded. If anyone can see any logic in why this is happening or can take a moment to look at the code below to se if I am doing something obvious wrong, that would be much appreciated Niclas Public Class Main Private Sub Lable1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Lable1.Click LoadForm(New frm1, SplitContainer1.Panel2) End Sub Private Sub Lable2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Lable2.Click LoadForm(New frm2, SplitContainer2.Panel2) End Sub Public Sub LoadForm(ByVal frmToLoad As Form, ByVal tab As Control) Try Dim Frm As Form For Each Frm In tab.Controls Frm.Dispose() Next Frm = frmToLoad Frm.TopLevel = False Frm.Parent = tab Frm.Show() Catch ex As Exception MessageBox.Show(ex.Message, "An error occured", MessageBoxButtons.OK, MessageBoxIcon.Exclamation) End Try End Sub Public Sub DisposePanelForm(ByVal TargetPanel As Panel) Dim f As Form For Each f In TargetPanel.Controls f.Dispose() Next End Sub Private Sub SideBar_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles Lable2.MouseEnter, Lable1.MouseEnter Dim lbl As Label lbl = CType(sender, Label) lbl.ForeColor = Color.Yellow End Sub Private Sub SideBar_MouseLeft(ByVal sender As Object, ByVal e As System.EventArgs) Handles Lable2.MouseLeave, Lable1.MouseLeave Dim lbl As Label lbl = CType(sender, Label) lbl.ForeColor = Color.White End Sub Private Sub Tab1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Tab1.Enter If SplitContainer1.Panel2.HasChildren = False Then LoadForm(New frm3, SplitContainer1.Panel2) End If End Sub Private Sub Tab2_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Tab2.Enter If SplitContainer2.Panel2.HasChildren = False Then LoadForm(New frm4, SplitContainer2.Panel2) End If End Sub Private Sub Tab2_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Tab2.Leave DisposePanelForm(SplitContainer2.Panel2) End Sub Private Sub Tab1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Tab1.Leave DisposePanelForm(SplitContainer1.Panel2) End Sub End Class Tag: Scrolling Menu Tag: 117670

Hi,

I have a menu which shows all the installed fonts on the system. The
menu is very big, and it grows too large to fit the current screen
resolution, and thus the scroll buttons are automatically added to the
top and bottom. I need to implement either of the following 2
solutions:

1. Provide for scrolling of the menu with mouse wheel, or
2. Stop the automatic scroll button from being added at the top, and
then implement my own scroll bar in the menu (something like MS Word
font selection control)

Any idea how i can proceed?

Regards,
Ankit!
