Debugger anomaly Paul Silvernail15-Dec-02 5:25 Paul Silvernail 15-Dec-02 5:25  This is a first !!!! After working on my final project for school late last night, I woke to find the debugger gremlins had come. When I try to debug my project (F5) MS VC# hangs. The task manager show a process for my app was created, but the app never shows up as a task. I tried deleting the debug directory and doing a rebuild, no luck! If I execute without the debugger (ctrl+F5), either in release or debug build, the app runs. Sounds like a real world release nightmare If anyone has ideas, please please let me know. Thanks, Paul Re: Debugger anomaly leppie15-Dec-02 5:34 leppie 15-Dec-02 5:34  Paul Silvernail wrote: I tried deleting the debug directory and doing a rebuild, no luck! Delete all them directories, and try again. I found that seems to work. A reboot is sometimes required.

James T. Johnson15-Dec-02 2:49 James T. Johnson 15-Dec-02 2:49  First get to the same directory your source code is located in then use the sn tool like so sn -k mykey.snk Now find the AssemblyInfo.cs or .h/.cpp file and find where it says In C#: [assembly:KeyFile("")] In C++: [assembly:KeyFileAttribute("")] Change the values of each to point to the mykey.snk file. In C#: [assembly:KeyFile(@"..\..\mykey.snk")] In C++: [assembly:KeyFileAttribute("mykey.snk")] Now you should have a strongly named assembly. The down side is that you need to do this to all assemblies your code references (excluding the ones that come with .NET).

It returns a gdi+ error This is what I do : tmpfileloc= apppath + "temp_make.jpg"; FileStream fs= new FileStream(tmpfileloc,FileMode.OpenOrCreate,FileAccess.Write); Image tmpimg= pictureBox1.Image; tmpimg.Save(fs,ImageFormat.Jpeg); fs.Close(); And the error I am getting is this : An unhandled exception of type 'System.Runtime.InteropServices.ExternalException' occurred in system.drawing.dll Additional information: A generic error occurred in GDI+. Whats wrong ? Tweety If you can smile when things go wrong, you have someone in mind to blame Re: Problem with Image saving leppie14-Dec-02 19:31 leppie 14-Dec-02 19:31  The only thing I can think of that perhaps the image format is not 24bppRGB. Maybe the stream need to have read rights as well or you perhaps dont have write access to the disk.

Re: Problem with Image saving Smitha Nishant14-Dec-02 19:46 Smitha Nishant 14-Dec-02 19:46  Hi Leppie, Thanks for the prompt reply. I am loading the image into the picturebox from a JPG file in my desktop. And the program does create a 0 byte file, when I try to save it. Then it crashes. Specifying the fileaccess as FileAccess.ReadWrite doesn't stop the error. What is 24bppRGB format ?

The way I was loading the picture into the picturebox was not perfect. I think that corrupted the image format. I fixed the issue. Thanks.

If I use an HTML button, it shows up fine. Both appear to be server side controls (both have runat="server". What's the difference between Web Form controls and HTML controls?

There can be many reasons, be a bit more specific. Maybe you are not running fast enough WebControls are server-side controls that normally will do some processing where HTML controls are basically literal controls. Both have a runat=server attribute, although its not required for HTML controls, but they are there so a literal control can "controlled" referenced from the server-side.

Re: Web Controls vs HTML controls JoeMcK15-Dec-02 9:18 JoeMcK 15-Dec-02 9:18  I've been trying to keep my samples as simple as possible...create a new project (web app). On the grid that's displayed, drop a web form button onto the grid from the toolbox...compile, then execute and the button doesn't show. Only labels show up. I have a feeling it's something silly that I'm just not aware of. It's been frustrating to track down why I don't see what I expect. When I drop an HTML button (from the toolbox) onto the grid, it shows up when I execute. Joe What kind of control should I use? Paul Silvernail14-Dec-02 12:40 Paul Silvernail 14-Dec-02 12:40  I was hoping to have a listview control in details view, where each column was bound to a data source. When the user clicked in a box (grid lines on obviously) a drop down box filled with the bound data should appear. Does anyone know if such a control exist . Maybe point me to an article detailing the procedure. Thanks in advance, Paul Re: What kind of control should I use? leppie14-Dec-02 12:51 leppie 14-Dec-02 12:51  I think you can do that with the datagrid, but to be honest I hate that thing. Either here (on CP) or on GotDotNet there should be a sample.

The program works and all but is set up too only encrypt one file at a time. im trying to find a way to encrypt a hole folder just by typing the directey i.e "C:\\my folder". I have just started programming...in c#(or any lauguage for that matter) so i need help with this perticular subject. I have been going at this a diffrent way (allowing the user to selected a file and writing the FileName to a listbox..then pulling the files off the list box 1 by 1 to be encrypted). please help me if you can. Re: how can i encrypt a hole folder? instead of 1 file at a time. leppie14-Dec-02 11:51 leppie 14-Dec-02 11:51  Directory.GetFiles returns a string[] with filenames and Directory.GetDirectories to get the directories. Then just setup a recursive function to "crawl" all the subdirectories. There is an recursive example on MSDN at this topic.

Burt Harris15-Dec-02 8:50 Burt Harris 15-Dec-02 8:50  The hourglass shape of the mouse cursor generally indicates that an applicaiton (as opposed to the mouse itself) is busy. If you're writing an application in C#, this is typically controlled with the Cursor.Current static property (in System.Windows.Forms). I'm not sure this will do what you want, but it's the right general direction. Burt Harris C++ to C# conversion? Zibar14-Dec-02 5:55 Zibar 14-Dec-02 5:55  This piece of code is from the DX8 tutorial: VOID* pVertices; if( FAILED( g_pVB->Lock( 0, sizeof(g_Vertices), (BYTE**)&pVertices, 0 ) ) ) return E_FAIL; memcpy( pVertices, g_Vertices, sizeof(g_Vertices) ); g_pVB->Unlock(); Is it possible to translate it in C#? I'm trying to write a simple DX8 application as I use only C#. I'm using the VB type lib but obviously there are functions not available in C# like D3DVertexBuffer8SetData, that replaces the above C++ code in VB. While this exercise might be a little unpractical it actually helps me better understand the difference between managed and unmanaged . Any ideas how to set up and run DX8 in C# (is it possible at all; is it possible to do it in a' managed' way)? Thank you Z. Re: C++ to C# conversion? David Stone14-Dec-02 6:01 David Stone 14-Dec-02 6:01  DX8 is a pain to work with in C#. If you can, I would just wait a few months for the DX9 SDK to come out. That'll have C# support. I don't know whether it's just the light but I swear the database server gives me dirty looks everytime I wander past. -Chris Maunder Microsoft has reinvented the wheel, this time they made it round. -Peterchen on VS.NET
