    - Popup window on top of another popup Hi guys, I have a grid editor, with cells (DevExpress). I have a custom cell edit, which contains two other edits. When I click the cell, I get the first popup edit. When I click the other controls contained in this popup, another window pops up. The problem is that the moment I click inside the second popup, the first one disappears, and as a consequence, the second one disappears too. Is there a way to keep the first popup visible, while the second one is editing? Thanks in advance, Cosmin Tag: Drag & Drop - multiple controls Tag: 116296

    - DoEvents for a specific thread? Hi, I have a thread (not the main) in my app that draws GUI. It's a STA-thread, and it seems OK. Though I would like to process its message queue, like Application.DoEvents (for the main thread). It should have a message queue since it draws GUI. How do I "do a DoEvents" for a specific thread? regards Carl Tag: Drag & Drop - multiple controls Tag: 116290

    - Different Image for Control I've built a control that will be placed in the VS.Net 2005/2008 toolbox, but it shows up with a default image that's not too attractive. What can I do, in order to add my own image? Tag: Drag & Drop - multiple controls Tag: 116284

    - subscribing to events in controls in a separate window in another window ? < .NET 2.0, VS Studio 2005 Ent., Win XP Pro SPII, all .NET Frameworks from 1.0 to 3.5 installed > ... note : normally I do not cross-post, but I felt this scenario justified sending to both the controls and windowsforms groups ... Hi, 1. Main form creates other top-level winform windows at run-time (new window parent == null) from a pre-defined form template as : secondaryFormTemplate newSForm = new secondaryFormTemplate(); // set formborderstyle, set to topmost, toplevel, etc. newSForm.Show; 2. On each secondary winform you create there is treeview (which has public accessor); you subscribe to the After_Select event of each Treeview IN THE MAIN FORM with the same event handler in the main form like so : newSForm.myTreeView.After_Select += new System.Windows.Forms.TreeViewEventHandler(secondaryTVHitHandler); 3. so the handler for all secondary treeview selection in the main form looks something like this : private void secondaryTVHitHandler(object sender TreeViewEventArgs e) { // do whatever, get the node from e.Node, etc. } This compiles okay, seems to work okay most of the time, but once in a while it appears that node selections in some of the secondary windows are not reported to the subscriber in the main form. So, I switched back to the more "classic" paradigm of having the secondary form template implement an After_Select event which raises a public event, which I then subscribe to in the main Form. Intermittent problems of some selection events went away. My question is : were the glitches I observed using the first technique possibly a result of threading problems involving separate independent top-level winforms ? Another hypothesis : the .net TreeView (now, like me, so long in the tooth :) is, as we all know, a wrapper around a COM control ... issues related to COM ? My sense is that it is "best practice" to have objects raise public events from their own internal private events, rather than have "alien objects" subscribe directly to events of objects, but in the case where the secondary objects (winforms in this case) are being created at run-time by a "master object" it is "tempting" to just subscribe to their events there. Appreciate any comments, recommendations, insights ! best, Bill Woodruff dotScience Chiang Mai, Thailand Tag: Drag & Drop - multiple controls Tag: 116282

    - Where can I find a list of the sequence of events that a vb.net form goes through... when the executable is first run? Where can I find a list of the sequence of events that a vb.net form goes through... when the executable is first run? (Before the user has moved/clicked/typed anything). What order do these happen: load, active, validate, paint, resize, shown, etc (And all the others.) I'm trying to run some of my own code just BEFORE the form is shown.... (but AFTER Load() has happened). Thanks. Tag: Drag & Drop - multiple controls Tag: 116278

    - Overriding dataset connection Hi I have a windows form app with one master table and several details (grids). As I am filling both the master and details using vs 2005 generated dataset and data adapters, there are multiple connection open/close during the whole operation (one connection open/close per adapter fill). Is there a way to override the vs generated connection management code to open the connection only once at start, do all fills and then close the connection at the end, to speed up the whole fill process? As dumping the vs 2008 dataset altogether will involve too much code writing, I am reluctant to let go of it and would prefer to only override the connection management if I can. Many Thanks Regards Tag: Drag & Drop - multiple controls Tag: 116272

    - Problem Drawing in a ListBox Subclass Good afternoon, everyone. I've subclassed ListBox to draw an icon next to each line, and it works! Except for one thing... when drawing items, it seems that SelectedItems and SelectedIndices is not perfectly current. This means that if I use it to draw, in some cases I may draw an item highlighted when it shouldn't be, or vice-versa. This mostly happens when dragging to select multiple entries. My temporary solution is to force a Refresh after every SelectionChanged event, but this makes the list less responsive. Basically, I'd like it to paint just like a normal listbox. So far I've only used this with an extended multi-select list box. This is the relevant code in my subclass: // Constructor: ... DrawMode = DrawMode.OwnerDrawFixed; DrawItem += Draw; SelectedIndexChanged += SelectionChange; ... // Handlers: protected void Draw(object sender, DrawItemEventArgs args) { args.DrawBackground(); int row = args.Index; Graphics graphics = args.Graphics; Rectangle bounds = args.Bounds; if (row != -1) { object item = Items[row]; // Draw the icon, if any Image icon = GetIconForItem(item); if (icon != null) graphics.DrawImage(icon, bounds.Location); // Draw the text, if any string text = item.ToString(); if (text.Length > 0) { int textHeight = Font.Height; int offSet = (ItemHeight - textHeight) >> 1; Brush brush = new SolidBrush(SelectedItems.Contains(item) ? SystemColors.HighlightText : ForeColor); graphics.DrawString(text, Font, brush, ICON_SIZE + 1.0F, (float)(bounds.Top + offSet)); } } args.DrawFocusRectangle(); return; } protected void SelectionChange(object sender, EventArgs args) { Refresh(); return; } Any ideas from the Windows Forms gurus? Thanks! Tag: Drag & Drop - multiple controls Tag: 116270

    - Draw PDF onto GDI+ Surface I have a WinForm application. I would like to be able to read a PDF, and draw it onto the GDI+ drawing surface, along with other commands that I would draw on the surface, to then print it.

    - Update other GUI via BackgroundWorker thread? Hi, I know that you should not update the applications GUI with code running in the BackgroundWorker thread (or any other thread). But is it OK to construct, show and update new Forms inside the thread? The difference I'm trying to point out is that you don't update any existing GUI, but instead, create (of example) a new small form with a progress indicator, OK? regards Carl Tag: Drag & Drop - multiple controls Tag: 116262

    - .NET Mass Downloader Version 1.2 Released We have improved the proxy support and added more samples of usage for 2005 , 2008 and Visual Studio Express Editions. You can get your copy from http://www.codeplex.com/netmassdownloader .NET Mass Downloader Welcome to the .NET Mass Downloader project. While it's great that Microsoft has released the .NET Reference Source Code, you can only get it one file at a time while you're debugging. If you'd like to batch download it for reading or to populate the cache, you'd have to write a program that instantiated and called each method in the Framework Class Library. Fortunately, .NET Mass Downloader comes to the rescue! Using .NET Mass Downloader Open a command or PowerShell prompt and navigate to where you extracted the current release. The tool itself is NetMassDownloader.exe and when run without parameters shows the following help screen: .Net Mass Downloader 1.0.0.0 - (c) 2008 by Kerem Kusmezer, John Robbins Batch download the Microsoft .NET Reference Source code. Usage: NetMassDownloader [-file <file>] [-directory <directory] [-output <directory>] [-vsver <version>] [-force] [-nologo] [-verbose] [-?] -file - Download an individual file's PDB and source code. You can specify multiple file parameters. (Short -f). -directory - Download all the found PDB and source code for all files in the specified directory. You can specify multiple directory parameters (Short -d). -output - The output directory for PDB and source files. The default directory is the cache directory set in Visual Studio 2008. By using the cache directory, you'll have the PDB and source files available to Visual Studio 2008. However, to use the .NET Reference Source Code with VS 2005, use the - output switch and in the Options dialog, Debugging, Symbols property page, add the specified output directory to the "Symbol file (.pdb) locations." Also, add the directory to the Solution Properties, Common Properties, Debug Source Files, Directories containing source code location. The Visual Studio 2005 debugger will automatically load the source code. (Short -o) -vsver - The Visual Studio version number to use for finding the cache directory. The default is Visual Studio 2008, but if you want to use the cache directory for Visual Studio 2005, you would pass '-vsver 8.0' (without quotes) (Short -vs) -force - If specified, forces the downloading the PDB files into the symbol server. When downloading to a symbol server if the PDB exists, it's not downloaded. Using the -output switch will always download and process the PDB. (Short -fo) -nologo - Don't show the logo information. (Short -n) -verbose - Do verbose output. May be worth turning on as the downloading source code can take a long time. (Short -v) -? - This help message. The only required arguments are -file or -directory, both of which can be specified as many times as you'd like. When you specify a directory, only the .DLL and .EXE files from that directory will be processed. If you wanted to download all the source code from binaries in the .NET 2.0 32-bit and 64-bit directories, the command line you'd pass is: -d C:\Windows\Microsoft.NET\Framework\v2.0.50727 -d C:\Windows \Microsoft.NET\Framework64\v2.0.50727. The main purpose of Net Mass Downloader is to populate the source code download cache for debugging, the default download location is the cache you specified to Visual Studio 2008. The -vsver switch to account for future Visual Studio versions so Mass Downloader could work with future CTPs and versions. While it's great to see the .NET Reference Source Code in Visual Studio 2008, there are a lot of developers out there who can't upgrade yet, but would love to be able to debug into the .NET Reference Source Code. If you specify the -output parameter, the PDB and .NET Reference Source Code will be written to the specified directory. In Visual Studio 2005, place that directory in the Options dialog, Debugging, Symbols property page. In the "Symbol file (.pdb) locations" list box as the first item. Also in the Options dialog, Debugging, General property page, uncheck "Require source files to exactly match the original version." Finally, in each Visual Studio 2005 project go into the solution property pages, Common Properties, Debugging Source Files, and in the "Directories containing source code" add the output directory to the top of the list. That's enough for Visual Studio 2005 to debug into the .NET Reference Source Code. When you first run Net Mass Downloader, you will be prompted with the current EULA for accessing the source code. If you don't agree with the Microsoft EULA, clicking the Decline button will not download the source code. The code download includes a detailed documentation about whole steps required to use it with VS2005 If none of the files can be downloaded please download and install the rtm version of the RTM Version of the .NET Framework 3.5 According to the Shawns Blog The Following Dll Are Enabled For Now: Mscorlib.DLL System.DLL System.Data.DLL System.Drawing.DLL System.Web.DLL System.Web.Extensions.DLL System.Windows.Forms.DLL System.XML.DLL WPF (UIAutomation.dll, System.Windows.DLL, System.Printing.DLL, System.Speech.DLL, WindowsBase.DLL, WindowsFormsIntegration.DLL, Presentation.dll, some others) Microsoft.VisualBasic.DLL But our framework supports additional versions without update if microsoft doesn't change the download engine. The original framework anouncement can be found here: Shawns Announcement Acknowledgements Thanks to the Developer Division at Microsoft. First they released the .NET Reference Source Code, and second for allowing a couple of developers to have some fun and provide a utility for the community. Thank you for using .NET Mass Downloader. We just ask that you log any bugs and features into the project Issue Tracker. Contact Information You can reach us via the discussions or you can directly mail me at keremskusmezer@gmail.com Development Details If you have questions about particular pieces of the code, Kerem Kusmezer did the following parts: the PE (Portable Executable) Parser, the PDB Parser, the Webclient Class. and the SrcSrv class.

    - Relative path that works in development and after deployment I was wondering if somebody could show me on how to use relative path in windows application that will work during DEVELOPMENT as well as after DEPLOYMENT. In short, here's my situation. During development the files in my project are located as follows: MyProject\bin\Release\MyApplication.exe MyProject\Settings\MyXMLFile.xml During development I use this syntax to load to MyXMLFile.xml from the .exe: xmlDocument.Load(@"..\..\Settings\MyXMLFile.xml"); Everything was fine until after I deployed the project whereas the file location now changed to: C:\Program Files\MyProject\MyApplication.exe C:\Program Files\MyProject\Settings\MyXMLFile.xml Now I started to get an error message stating that file 'C:\Settings\MyXMLFile.xml doesn't exist'. Please keep in mind these limitations: 1. I do not want to hard-code the relative path in app.config, I just want to use relative path. 2. I cannot use resource file because I need to change the MyXMLFile.xml during runtime. 3. Basically what I need is the relative path that can point to the project folder instead of the .exe, much like ~ sign to point to application root folder in web application.

    - NumericUpDown ValueChanged not firing - scrollwheel+shift key pres Hello, really hope you guys can help. I'm using a standard NumericUpDown control on a form, and trying to change the increment depending if a Control.ModifierKeys is pressed when the mouse scrollwheel is moved. Default increment is 0.5 When Keys.Control is pressed and I roll the mousewheel, the increment is adjusted to 5 and the ValueChanged event firest. Great. But when Keys.Shift is pressed and I roll the mousewheel, the increment is adjust to 1 BUT ValueChanged does not fire, so the value in NumericUpDown doesn't get adjusted. Not so great. I'm really confused as to why Shift would not cause ValueChanged to fire. Here's the little bit of code : private System.Windows.Forms.NumericUpDown numPrice; this.numPrice = new System.Windows.Forms.NumericUpDown(); private void numPrice_MouseWheel(object sender, System.Windows.Forms.MouseEventArgs e) { //check it's capturing if (Control.ModifierKeys == Keys.Shift) { numPrice.Increment = 1; } else if (Control.ModifierKeys == Keys.Control) { numPrice.Increment = 5; } } I guess I can manually fire ValueChanged after Shift and bodge it in some way?

It modifies a property of an object which causes a separate visible TabControl to rebuild the tab pages.

My question is, if I use the splash screen feature from App Properties->Application->Splash Screen does it add to the app loading time and am I better of running the splash screen using the background worker?

    - Initial opening speed Hi My vb.net seems to be slow on initial loading. My clients are not impressed as they had used the ms access version of the app previously and think that the old app is faster in loading. I understand .net apps need to compile themselves before execution. Is there any way I can speed up this process or in general do anything else to speed up initial loading of the vb.net app?

    - UserControls? I am a web developer by trade, but have done a little with winforms. How can I add a winforms user control to an application without having to create a separate project for each control? From what I have been reading, you need to create a project for the user control, build it, and then add it to the tool box. Once it is in the tool box you can drag it onto the form or other control. I want the user controls to be part of the base project and add them to the forms without having to build them each time I make a change. Can I modify the designer.vb file to do what I need?

    - DataGridView & TabPages Hi, This is my first message to this group. I've already search the web, google, this group, found some clues to my problem but found no solution or workaround. So please let me explain my problem: I'm developing an application, which has custom UserControls containing DataGridView controls being put inside TabPages of a TabControl at runtime (I hope this made sense). Well, those are being added dinamically at runtime simply because VisualStudio keeps deleting my controls due to a bug in the designer. This is a issue, but the problem I'm facing now is other. Please check those images: http://www.comp.ufscar.br/~cesarsouza/archive/CSharp/bug/ The first image is of my application, windowed, in normal mode, with the DataGridView loaded. Then, the window is maximized in the second image, and you can notice the grid didn't resize itself. Now, the third image reveals that the 'gap' produced is indeed not being redraw at all. The DataGridView is anchored on the four directions inside the UserControl, which is set to DockStyles.Fill inside the tab page. An interesting thing is, everything happens normally _before_ the data has been loaded and the data is bound. The same occurs backwards, i.e. If I load the data when the window is maximized and then resize it, the DataGridView gets bigger than its container control and becomes corrupted. I'm pretty sure this is a bug in the framework (I'm using 2.0) dealing with DataGridViews being put inside TabPages. If someone has already face this problem, please let me know. If nothing else works, I would like to know how I could force a complete redraw, or a re-bind after I completed a resize move. Just calling dataGridView.Refresh(), Invalidate, Redraw, or whatever seems to have no effect. Thanks in advance, Cesar Souza Tag: Drag & Drop - multiple controls Tag: 116146

    - Dynamic event handlers Hi, I am trying to dynamically generate a menu, based on entries on a text or xml file. The text file contains the "tree" after which the menu will need to be created. Something like the following: Level 1 -- Level 2 -- Level 2 Level 1 -- Level 2 ---- Level 3 I can read the file and generate each menu item definition, with the corresponding "nesting", without a problem. What I'm having difficulties with is deciding on how to handle the events for each of the menu items. Generating the full menu dynamically would mean having to create the event handlers dynamically, unless I have a fixed amount of event handlers, which I'm not sure is the best approach. I might be wrong here... 1. What's the best way to generate event handlers dynamically? I've read about runtime IL generation, which makes sense but is a bit complex. 2. Using regular event handlers (hard coded), can I capture which of the menu items is being clicked and what component is the menu being displayed on? i.e., if the menu is being displayed after a right click on a button or a picture box, can I: 1) know if it's the picture box or the button displaying the menu? and 2) can I know what menu/sub menu is being clicked? Any ideas will be greatly appreciated. Thanks, </edwin> Tag: Drag & Drop - multiple controls Tag: 116136

    - managed Multimedia development I may be missing something, so I'm making this a general question. I need to do some multimedia work. Essentially display a movie image (or two in one windw) plus some text and overlay text. For the overlays to work I'll need to be able to identify the movie frame being shown (ideally via an event). I expect to use Windows Media Video 9 movies as a minimum, though Flash support would also be nice, and Quicktime support nicer still. The end devie will be semi-embedded, and run on XPe at least, though I'd love to be able to compile onto the .NET CF and run under CE6.0. I've been working with the Quartz library and a public domain managed code wrapper for that library. To the question - there must be a better way than this! Have I completely missed some .NET class? Yes, I've messed with the Media Player DLL but that just doesn't have the fine control of the Quartz functions .. but the Quartz functions are not managed and the process of calling it from a .NET environment is .. well .. kludgy.

I've recently migrated from VB.NET to C# and have 3 questions about drag/drop
differences between the two languages...

Question 1) I'm tweaking a C# app (DotNet 2.0) to support file drag/drop.
I have 2 textboxes with Browse lookups, but I realized some users prefer to
drag drop files from folders on the desktop. The examples I've seen are for
1 drop location on the windows form.

Are there any examples of implementing drag/drop for multiple controls?

Question 2) Take a look at the following function header:

private void txtFileToProcess_DragDrop(object sender,
System.Windows.Forms.DragEventArgs e)
{
//my code here...
}

What ties this function as the handlerto the txtFileToPRocess control?

Question 3) How do I add event handlers on the fly? This was trivial in
VB.NET; you simply selected the control (in the dropdown), then the event
(in an adjoining dropdown).

Thanks,

Top
