    - Smart Client Software Factory Hi Has anyone used Smart Client Software Factory http://msdn.microsoft.com/en-us/library/aa480482.aspx? Does it have any benefits in winform database app development? Thanks Regards Tag: Data Selection Mode in Combo Box Tag: 117808

    - Encrypting and Decrypting AppConfig Hi, You can encrypt and decrypt AppConfig using the "ConfigurationSection.SectionInformation.ProtectSection" method as follows. //To Encrypt Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); ConfigurationSection cons = config.AppSettings; cons.SectionInformation.ProtectSection("DataProtectionConfigurationProvider"); cons.SectionInformation. cons.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); //To Decrypt Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); ConfigurationSection cons = config.AppSettings; cons.SectionInformation.UnprotectSection(); cons.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); But the limitation here is that it is machine specific, in the sense that you can only decrypt in the same machine where you encrypted it. For an example say that you want to deliver a solution to a customer with sections in AppConfig encrypted, once you encrypted it in the developer pc, you wont be able to access information in AppConfig in client's pc even through the program. So this is not possible if the machines are changed in the process. Seems it takes internal machine specific keys to do the encryption and seems there is no way to specify a custom key which can be delivered to the customer for decryption. Even the class "SectionInformation" is seeled so that cannot derive it and do any modifiations. One way to overcome this is by, encrypting it while installing using a post action command in the Setup project. So then it will become machine specific and can decrypted as needed. But what I want to know is, is there any other work arround for this? I would like to know all the other ways if there are possibilities to do this. Please let me know if you know anything regarding this. Thank you Dilum Tag: Data Selection Mode in Combo Box Tag: 117807

    - Force dropdown of DataGridViewComboBoxox Any help would be appreciated: Is it possible to programmatically force a datagridviewcombobox to open its dropdown? The reason is, I have to click twice one the cell to make it drop down: one to get focus and the next click to drop down. I want it to drop down at the moment it gets focus.

    - Dynamic colouring of areas of image 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!!

    - Scrolling Menu 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?

    - 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: Data Selection Mode in Combo Box Tag: 117793

    - 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: Data Selection Mode in Combo Box Tag: 117775

    - 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: Data Selection Mode in Combo Box 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: Data Selection Mode in Combo Box Tag: 117751

    - I started a robocopy on friday using the /z switch.... The source machine was rebooted in the middle of the copy. I was hoping to be able to start the copy over again from where it left off. 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?

    - 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: Data Selection Mode in Combo Box Tag: 117736

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.

    - 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: Data Selection Mode in Combo Box 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. Pressing ESC does nothing. In order to continue, I must close the window and begin again, but as soon as I select text, the problem occurs again. I don't have this problem in the VB6 IDE or in Word. I have a second machine that uses the same mouse and keyboard through a switch and I don't have the problem in VB.Net on the second machine, so it's not the mouse or the keyboard. I need to be using the machine that's having the problem. Has anyone seen this before? If so, how do I fix it? Thanks in advance, Carol Tag: Data Selection Mode in Combo Box Tag: 117712

    - 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: Data Selection Mode in Combo Box 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 ...

    - Equivalency to TransparencyKey in WPF? 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!

    - 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: Data Selection Mode in Combo Box 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: Data Selection Mode in Combo Box 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?

    - 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: Data Selection Mode in Combo Box 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: Data Selection Mode in Combo Box Tag: 117675

I have a desk top application where the user selects an item from a combo
box and the resulting selection populates other parts of the form. The list
is quite exhaustive and I'd like to let the user type the name and match on
more than the first character that I get by setting the combo box's
DropDownStyle to DropDownList. Do I need to get a custom control? Any
suggestions?

TIA
