    - Application settings Hi For my db app, I need to save the location of the db (really a windows path) which normally only needs to be set at the first app start (I can check if the setting is missing and ask user for a value). Occasionally (once in a blue moon) I may need to change this setting in case db is moved to a different server etc. My question is what sort of mechanism can/should I use to store this setting? Thanks Regards Tag: Shared control tab Tag: 103991

    - Resource satellite assemblies - max size? Hi, We are building a big enterprise class product using winforms. The product needs to support multiple langauges. So we have separated all resources, esp strings, in separate resource assemblies which are loaded based on the culture. We have separate assemblies for labels, messages, errors and hint messages. we had also planned to have separate satellite assemblies for each module. We have around 10 modules each of which could contain many thousands of string resources. Some string resources are common across modules, so we had planned to keep them in common assembly. We have the following questions related to the resources: 1) What would be the impact on performance (of GetString) if we have a single satellite assembly instead of multiple ones which could contain close to a million string resources compared to the approach of opening two to three different resource files which could contain 1/10th of the total number of strings? Are the strings indexed in some way? 2) Is there any recommendation on the maximum size of a resource file containing string resources? (Individual strings are not big, but the total number is big.) We are debating having multiple resource files(satellite assmeblies) per module versus single reosurce file for the whole product. With mutiple resource files, we will need to open separate resource managers and with single resource file we are concerned if the search to find a string using GetString would slow down our application. Separate resource files will allow us to give smaller patches to our customers (we have needs to customize parts of product). Ideas/thoughts/recommendations would be appreciated.

    - Changing items in bound ComboBox I have a combo box (dropdown) that is bound to an array of objects with the member specified by a property name. There is one item on the drop-down that when selected I want to be able to change the text displayed. I cast the selected item to my object and set the value that I want to change. The text shows in the debugger just fine but both the selected text and the drop-down text is not correct and the properties are never queried to get the new text. It is like the drop-down is ignoring the fact that the field has been changed. How do I make sure that the drop-down first, knows to requery for the changed item and second, displays the correct updated text? Thank you. Kevin Tag: Shared control tab Tag: 103965

    - Strange mouse behaviour on form? (VS2003) Hi All, I have a very straighforward form with a number of text and other fields on it, which are bound to fields in a data source. All the fields get populated properly from the database, but there is a strange problem with mouse usage. If I click anywhere in a text field, the flashing cursor will only appear at the beginning of the field - regardless of where I click. I can't highlight any text in a field by dragging with the mouse. I can get a word in the field to highlight by double-clicking on it, and I can move the cursor around with the keyboard. Any clues? I've never seen this before, and it doesn't happen on any other of my forms, as far as I know. About the only thing unusual is that it is an MDI child window - it is invoked from a "sibling" MDI child window like this: Dim f as New frmShowOne f.MdiParent = Me.MdiParent f.Show() Tag: Shared control tab Tag: 103964

    - Combo Box not Repainting when updated out of focus I am using C# on a windows form with three tabs. Each tab holds a user control and there are several combo boxes on each user control. On all three user controls there is a combo box that contains information from the same location in a database. but the information is displayed differently in each instance. In one combo box all values from the table are displayed, on another box only the values that meet a certain criteria are displayed and on the third combo box only the values that meet an additional criteria are displayed so all three display different information from the same source. On one of the controls I can update the information in the DB. When I do so I want the other combo boxes on the other user controls to update their information, essentially requery the database and redisplay the new information. This works fine for the combo box that is on the user control in focus but the user controls on the other two tabs that were not in focus when there combobox data was updated seem to lose the ability to repaint themselves. However they do seem to have the updated information. I can click where the drop down arrow is though I cannot see the drop down arrow. The combo box will drop down and show the values inside though the text box portion will not repaint. I can scroll through the list of values in the dropdown though I cannot see the combo box scrolling and I can select a value, though I cannot see the value I scrolled to. The combo boxes that were out of focus when their data was updated will not repaint until I close and reopen the form. I also tried a different method of throwing an event on the user control in focus that told the parent form that the combo boxes need to be updated. The parent form in turn would notify the other user controls that they needed to update their combo boxes by setting a variable and then on the Enter event on the other user controls I checked the variable to see if it was true when the user control comes into focus and if so would requery the info in the database and refill the combo box but this did not work either. The combo box will not repaint it self even though its info if updated when the combo is in focus it appears. It seems this has something to do with the idea that you should not update the UI directly from a worker thread but should call the UI's Invoke method for updating which I tried doing as well but it does not seem to work either.

    - VB 2005 visualstyles problem. My application seems to be ignoring Enable XP visual styles, which is ticked on in the application properties. the Toolbar and Menubar, which appear the nice looking shaded blue appear like that whilst in the IDE, but when I run the app, they both go to boring grey. In the application.designer.vb self generated file, it does have PublicSubNew() MyBase.New(Global.Microsoft.VisualBasic.ApplicationServices.Authent icationMode.Windows) Me.IsSingleInstance = false Me.EnableVisualStyles = true Me.SaveMySettingsOnExit = true Me.ShutDownStyle = Global.Microsoft.VisualBasic.ApplicationServices.Shutdow nMode.AfterMainFormCloses EndSub If i create a brand new application, just as a test and drop the two controls into that, they appear with visual styles. So it looks like its something to do with my project, but i can't find out where or why. any help appreciated. Cheers Nig Tag: Shared control tab Tag: 103957

    - ComboBoxColumn = Slowww I have a DataGridView with about 450 records. There are five columns: three ComboBoxColumns and two TextBoxColumns. When loading the Form, even after all the BindingSources are filled, it still takes a long time before the data shows (and I'm running on a pretty fast machine). Also, if you try to re-sort one of the columns, it sits there for a good long while before it redraws the table. So, I was thinking, if it's possible, maybe I should just use standard columns (TextBoxColumns) and then use event handlers to insert and remove ComboBoxes on the fly on an as-needed basis. This seems like it would speed thinks up a lot but I can't figure out how to change an individual cell's EditingControl from a TextBox to a ComboBox. Please advise. Thanks in advance, -Dan Tag: Shared control tab Tag: 103944

    - How to elegantly handle resizing dialog box in 2005? I have a dialog style application that uses DirectX to play DVD movies. In the center of the form is the main panel where DirectX displays the movie. Around the edges are various list controls, checkboxes and buttons. When the window is resized, I only want the main panel to resize and everything else to stay as stationary as possible. In the case of vertical resizing (expansion), I would like the controls on each side of the main panel to expand proportionately. However, I want the buttons on the bottom to stay the same giving all the new room to the main panel. I could override the OnResize and write the logic to reposition all the controls. Uggghhh... Does .NET 2005 have anything like a java gridbaglayout manager? I know .NET 2003 could resize a dialog box and allowed you to specify how it would resize. But this did not give me enough control and I experienced very ugly results. Is 2005 more sophisticated in this way? Thanks, Siegfried Tag: Shared control tab Tag: 103943

    - How can I keep a contextmenustrip from adding Icons in task bar? Hi, I am working on an app that can launch launch other apps. I then setup a hook into the systems menu of these apps that posts a message back to the parent app. This message is used to display a special context menu that runs in the original app's process space, but is displayed on top of the child app that invoked it. This actually works. The problem is that when the contextmenustrip shows up, it is matched by an item in the task bar. This item has an icon but no title. To top it off, if I open a drop down menu on the contextmenustrip, another identical item shows up in the task bar. Tag: Shared control tab Tag: 103937

If I want to use GACUtil do I have to sign my project?

    - UserControl Docking/Resizing Problems I have a UserControl (size = 800 x 600) that contains a TableLayoutPanel. The TableLayout Panel's Dock property is set to Fill. When I place this UserControl in the left panel of a SplitContainer and set its Dock property to Fill, it takes on the size of the panel (500 x 600), but the TableLayoutPanel remains 800 x 600. If I return to the design tab for the UserControl and change it's size manually to 500 x 600, however, the TableLayoutPanel resizes as expected. Note: I experimented with the AutoSize, AutoSizeMode, and Anchor properties but none of these made any difference. Another Note: If I change the size of the left panel of the SplitContainer to 900 x 600, the TableLayoutPanel *expands* to fill the extra 100 pixels. So, expanding works but shrinking doesn't. And this is true even if I set the AutoSizeMode to GrowAndShrink. Any idea what's going on here? Visual Studio bug or programmer error? :) Thanks, -Dan Tag: Shared control tab Tag: 103905

There is one thing though that the designer fails to do: it does not add the necessary: this.userControl1.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] {this.columnHeader1,this.columnHeader2,...}); into the InitializeComponent() Method in the UserControl.Designer.cs. What do I need to do to make that happen ? Tag: Shared control tab Tag: 103882

    - Reset DropDown ASP.NET 2.0 webapplication DropDown list and button on same page DropDown_SelectedIndexChanged - redirect to selected item value Button_Click - redirect to another location Select item from dropdown correctly goes to selected location. Back arrow returns to my page. Selected item is shown as selected. Selecting button transfers to previously selected item Url and not the Url in the Button_Click handler.

    - Defaults for data bindings Update Mode When you bind a data source to a control the binding data source update mode defaults to "OnValidation". I find this a pain and I would prefer the default to be "OnPropertyChanged". Does anyone know if this default could be changed or how I could go about overriding this behaviour. e.g. using descendant controls. I only want to change the default (I might need to change it back to "OnValidation" if needed.

    - NumericUpDown select contents I am having a hard time trying to select thet contents of a NumericUpDown control when it gets focus. When the control gets focus I want all the contents to be selected so that the user would per default overwrite it when she enters data. Basically I overrode OnEnter and did this.Select(0, this.Value.ToString().Length); (seems a bit cumbersome, but I haven't found a better way of doing it). Nothing happens. MSDN documentation states NumericUpDown should have a Text property, I can't see that it does. It does not have a Selection property either, so if I needed the actual selected numbers I don't see how I would get that. When you TAB into the control the contents is selected (as I want it) so I know this must be possible to do when I select it with the mouse also. Thanks. Tag: Shared control tab Tag: 103857

    - Urgent Help - SMTP mail I have created the send mail application in console application of c#.net 1. When I set my smtp server as some ip address which is a smtp server and when the smtp runs in my local machine where my exe resides, the mail is sent perfectly. 2. When i specify the ip address of some amtp server in my intranet and when the smtp server is not configured in my local machine whre my exe resides, the send mail fails. My doubts: 1. Eventhough i sent it to the correct ip address of local intranet which is having amtp server , why it is not working? 2. Does it expect to run smtp service in the local machine? 3. Whether smtp has to be configured in local machine. But logically it should not be the case. It should work eventhough the smtp is not configured in the local machine and if it is configured in any other machine which is having amtp server 4. some of the sites specified that the smtp server should be hard coded as "localhost". Is it so? Please help me ASAP. Its urgent Tag: Shared control tab Tag: 103852

    - Windows App Freezing I have a muti-threaded windows app that creates child forms in a separate thread which then invoke a delegate on the MDI parent form. I have put all time-consuming tasks on separate background workers like running stored proc, poppulating data grid, etc. I am running VB.Net 2005 on Windows 2000 SP4 and on XP SP2. After a period of inactivity in the app (15-30 minutes), it freezes. The task manager says its running but I cannot switch to it. I tried using the DoEvents method on a timer but that had very strange results - the app was responsive but all the functionailty errored out. I read up on message pumps and STA model. Even though its should be an MTA, when I try and do application.run - it forces me to create the MDIFrm as STA or a Treeview control on it will not register drag-drop events. I am not using application.run but have set the MDIForm as startp form (and not set it to run as single instance so it should be STA). I am not using any COM but am using Infragistics 3rd party grid control and dock manager. Both are .Net components and don't require registering. The MDIForm as a treeview, dockmanger and a tablelayout panel prior to opening child forms. Any ideas why this freezing is occurring? It was much more frequent (even if there was activity) on XP with SP1 but with SP2, it was much less. Please advise. Thanks Anita Tag: Shared control tab Tag: 103849

    - Installing Windows XP x64 I bought and built a new couputer a few months ago. Part of it was a copy of Windows XP x64 Professional. Every time I have installed the windows I have run into a problem during the Finalizing Installation phase of the installation. During the Saving Settings the installation locks up and stops with a time of 8 or 9 minutes remaining. I have tried switching the CDRom thinking that maybe it was bad. If I just leave it there and see if it will get past it and is just running slow, eventualy the screen saver and eventualy sleep mode kick in and the installation just stops. I am out of ideas as to what it might be. Tag: Shared control tab Tag: 103846
