    - When to use the GAC and how. ? Okay, this is really a three part question. I'm trying to figure out how this whole GAC thing works. Here goes.... 1. When should you put an assembly in the GAC as opposed to just referencing the dll in a normal windows folder? 2. When you put it in the GAC how should you reference in the project? I would think that you shouldn't have to reference it because it's in the GAC, but it looks like you still do? If so, what's the benefit? 3. When should you set "CopyLocal" = False in the assembly reference properties in VS.NET? thanks in advance. Mark Tag: .NET software development tools Tag: 54157

    - URGENT: Internet Explorer Control: Print not working Hi, I have an ASP.NET page that sends a request to the server to generate some html on the fly and print it through the server. Once the request comes in, the page is generated. I have a Internet Explorer Control that loads this page on the server side. Then I am calling the print function to print that page. The code compiles and runs, but this page is not printed after the printing request has been executed. There is nothing in the print spooler. Here is the code ======================================================= Private WithEvents browser As SHDocVw.InternetExplorer browser = New SHDocVw.InternetExplorer() browser.Navigate(url) While (browser.QueryStatusWB(SHDocVw.OLECMDID.OLECMDID_PRINT) <> (SHDocVw.OLECMDF.OLECMDF_SUPPORTED + SHDocVw.OLECMDF.OLECMDF_ENABLED)) End While browser.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER) ======================================================= everything executes fine, but there is nothing printed. The control navigates to the correct page. Does anyone know why it doesn't print ? Only reason I can think of is the control is designed for WinForms and not for Server Side Classes (not web forms, just a class on the server side). Please help!!! Regards, Shardool Karnik.

    - define method that takes a method? Before offering architecture advice please read the short documentation for this project at: https://sourceforge.net/docman/display_doc.php?docid=18381&group_id=87262 if link does not work? try: http://sourceforge.net/projects/genadonet and go to "Docs" page, only 1 doc available... I have a generic data access DLL that returns IDbDataAdapter for a given data provider which is dynamically loaded at runtime. Unfortunately IDbDataAdapter does not have the event 'RowUpdated' defined. however, every provider has this method that takes basically the same arguements. OleDbRowUpdatedEventArgs inherits from RowUpdateEventArgs OleDbRowUpdatedEventHandler is defined as: OleDbDataAdapter.RowUpdated(object sender, OleDbRowUpdatedEventArgs e) SqlRowUpdatedEventArgs inherits from RowUpdatedEventArgs SqlRowRowUpdatedEventHandler is defined as: SqlDataAdapter.RowUpdated(object sender, SqlRowUpdatedEventArgs e); same for Oracle, and Odbc providers... I don't have a clue why IDbDataAdapter does not define RowUpdated?! Anyway I have a "generic ADO.NET" project which you can see from link in my signature. basically I provide a method that returns an IDbDataAdapter. Actually, I have one for each overloaded constructor of IDbDataAdapter. i have similar overloaded methods for all other IDb types (Connection, DataParameter, Command). The client can now develop database provider independant code. The provider used is determined at run-time. Since IDbDataAdapter does not define any events, I need to supply a way for users of the generic ADO dll to subscribe to them. So far i created a method defined as... ============================================== public interface IDbTemplate { ... void DataAdapterSubscribe(IDbDataAdapter da, DataAdapterEvent evt, Delegate target); ... } ============================================== DataAdapterEvent is an enumeration of events supported by all providers (Disposed, FillError, RowUpdated, RowUpdating) 'target' is supposed to accept a method pointer. Am I declaring it as the wrong type? here is how I implemented this for the Sql provider... ============================================== public class DbSqlTemplate:DbTemplate { ... public void DataAdapterSubscribe(IDbDataAdapter source, DataAdapterEvent evt, Delegate target) { SqlDataAdapter da = (SqlDataAdapter)source; switch(evt) { case DataAdapterEvent.RowUpdated: da.RowUpdated += new SqlRowUpdatedEventHandler( (SqlRowUpdatedEventHandler)target); break; case DataAdapterEvent.RowUpdating: da.RowUpdating += new SqlRowUpdatingEventHandler( (SqlRowUpdatingEventHandler)target); break; case DataAdapterEvent.Disposed: da.Disposed += new System.EventHandler( (System.EventHandler)target); break; case DataAdapterEvent.FillError: da.FillError += new FillErrorEventHandler( (FillErrorEventHandler)target); break; } // end switch } // end method ... } //this code compiles with no errors or warnings... ============================================== In the client I am trying to use this as follows: ============================================== public void ReQuery(...) { ... _da = _context.DbContext.DbTemplate.DataAdapter(cmd); if (!_context.DbContext.DbTemplate.SupportsMultiStepStatements) { //subscribe to the RowUpdated... _context.DbContext.DbTemplate.DataAdapterSubscribe(_da, GenDB.Data.DataAdapterEvent.RowUpdated, this.OnRowUpdated); //compile error here... // "method referenced without parenthesis" } ... } protected void OnRowUpdated(object sender, System.Data.Common.RowUpdatedEventArgs e) { if (e.StatementType == StatementType.Insert) { if (typeof(Int32) != typeof(System.Guid)) { //numeric pk IDbCommand cmdIden = GetIdentityCommand(); object newID = cmdIden.ExecuteScalar(); e.Row["ProductID"] = newID; } } } ============================================== -- Michael Lang, MCSD See my .NET open source projects http://sourceforge.net/projects/dbobjecter (code generator) http://sourceforge.net/projects/genadonet ("generic" ADO.NET) - does not yet include above described feature Tag: .NET software development tools Tag: 54153

    - Sluggish Performance All Round I'm just wondering if anyone else feels the same way I do. I find Windows XP Pro an annoyingly sluggish O/S where almost every basic task has an associated (and noticeable) reaction time. I've got a couple of hi-spec desktop machines but it doesn't seem to matter how much horse-power I throw at it (cpu, hd, hd controlllers, ram, etc) it still runs like a dog. I've tried turning off just about every "advanced" (aka power-sucking) feature but it doesn't make a jot of a difference. THEN, on top of this creaker we have to add the .NET framework and Visual Studio... and it's like being back in the days of 300 baud terminals (without a GUI, of course). Maybe you disagree?

    - Shared Assembly Problem in Remoting I am having a problem when using a shared assembly with remoting. I have a shared assembly (shared.dll) added in the gloabal assembly cache. The remoting server application (server.exe) uses this shared.dll. I have added a reference of this assembly with set local property false. On client application (client.exe), i have also added the shared.dll assembly's reference. When i execute the server app (server.exe), it starts with no problem. When i start the client application, it gets crashed with the FileNotFoundException saying that it can't find the shared.dll assembly and shows the server assembly's path while the server continues to execute without any problem. I have managed to solve the problem by making the copy local property of shared.dll assembly's reference to true at server side. But, this is not what required... I want to use the shared assembly from its original location (global assembly cache). If someone can tell me what exactly is the problem, i would be grateful.

I mean by this accessing the objects that are created on the given slide. I would like to identify the selected object, maybe check its category (arrow, text, etc), take and pass it to my program. Then put the changed object back into the slide instead of the selected object. Off course I will ensure the right format. But what format is it?

    - HttpWebRequest - the 6 million dollar question I'm posting this again as it's been 1 week now and still not a single reply, surely someone must have come across this problem! I've hit a brick wall with this one.. I'm trying to perform a HttpWebRequest that posts form data to the target server - the problem is that the request *always* contains an Expect: 100-continue header, which on HTTP 1.0 servers results in a 500 error. None of these seemingly obvious fixes work: Set the HttpWebRequest.Expect property to null or String.Empty Set the HttpWebRequest.ProtocolVersion to HttpVersion.Version10 Note that my class works perfectly with HTTP 1.1 servers, so I doubt there's anything I've done incorrectly in code. Also note that the problem only surfaces when you POST data to the server with the request, no post data = no problem. Searching google for this problem has given me a few people that have hit the same problem, but not one valid workaround. Help! Tag: .NET software development tools Tag: 54100

    - async callback problem Hi, I'm using a async callback mechanism to receive data from the socket. Once the data is received, I parse the data and if certain information is received I open a new form. Everything goes fine until the form is opened. The opened form seems to freeze and does not refresh (no errors are generated). However, If I output the received data to the console it seems to be receiving data. The problem is only with the UI. Part of the code is included below (pls let me know if you need the entire source code). private void Receive() { try { if ( callbackProc == null ) callbackProc = new AsyncCallback(ReceiveCallback); StateObject state=new StateObject(); state.workSocket = s; s.BeginReceive(state.buffer, 0, StateObject.BufferSize, SocketFlags.None, callbackProc, state); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void ReceiveCallback (IAsyncResult ar) { try { StateObject state = (StateObject) ar.AsyncState; int bytesRead = state.workSocket.EndReceive(ar); string szData = System.Text.Encoding.Unicode.GetString (state.buffer, 0, bytesRead); frmNew n = new frmNew(); n.show(); Receive(); } catch (Exception ex) { throw new Exception(ex.Message); } } Tag: .NET software development tools Tag: 54097

    - Reflection: Get type signed with attribute Hi! We defined an attribute that can be applied to a type multiple times (AllowMultiple = true). A type can have numerous instances of that attribute that it may have inherited from its base classes. Problem: If we have an instance of that attribute how can we find out which class originally was signed with that specific instance. E.g: [AttributeUsage( AttributeTargets.Class, AllowMultiple = true )] public class MyAttribute : Attribute { public MyAttribute( int intVal ) { ... } } [My(1)] class Base { } [My(2)] class Child : Base { } So Child is signed with My(1) and also My(2). If we have My(1), how can we get the type that was signed with My(1), in this case Base. TIA, Markus -- ########################################## Please do not send replies to msdngroups@syska.de.

    - FileSystemWatcher returns changed files in lower case Hi, The FileSystemWatcher works fine to return the files changed. However, the path returned through FileSystenArgs.FullName is always in lower cases, e.g., c:\projectfiles\watched\foo.txt even though both the directory and file names are in proper case like c:\ProjectFiles\Watched\Foo.txt. I've tried to instantiate a DirectoryInfo or FileInfo with the returned file path, hoping they will return the path in proper case but without success. Is there a work around? The project I'm working on copies the changes to another machine so it's important that I can maintain the case so users won't get confused.

    - Please help us... POSTing with Http/WebRequest I have noticed that a lot of people were having a similar problem to mine which involves using the POST method with the HttpWebRequest/WebRequest/WebClient classes (.NET 1.1). The classes will send out one HTTP packet that says content of a certain length will follow but the second packet is never sent, which usually results in a 400 error from the server. I've tried my code on both HTTP 1.0 and 1.1 servers and both gave the same result. Here is my example: Try Dim LogInURL As String = "http://s2.starkingdoms.com/scripts/main.cgi" 'Dim LogInURL As String = "http://sklone.homeip.net/scripts/BrowserLogin.aspx" Dim Account As String = "blah" Dim Password As String = "blah" Dim Request As Net.HttpWebRequest = Net.HttpWebRequest.Create(LogInURL) Request.ContentType = "application/x-www-form-urlencoded" Request.Method = "POST" Request.ProtocolVersion = Net.HttpVersion.Version10 'Request.ProtocolVersion = Net.HttpVersion.Version11 Dim RequsetStream As IO.Stream = Request.GetRequestStream() Dim ASCIIEncoding As New System.Text.ASCIIEncoding Dim PostData As Byte() = ASCIIEncoding.GetBytes("Account=" & Account & "Password=" & Password) RequsetStream.Write(PostData, 0, PostData.Length) RequsetStream.Close() Dim Reader As New IO.StreamReader(Request.GetResponse().GetResponseStream()) Dim ResultHTML As String = Reader.ReadToEnd() Reader.Close() MsgBox(ResultHTML) Catch ex As Exception MsgBox(ex.Message) End Try And here's what happens: POST /scripts/main.cgi HTTP/1.0 Content-Length: 25 Connection: Keep-Alive Host: s2.starkingdoms.com Followed by the Bad Request (400) error.

    - Multiple frameWorks, Serialization and Versions Hi I got some type of form designer where I could open up a .net form (done with reflection in run time so I'm not using design time environment or anything) move controls around and finally save the form. What it really saves is an xml file where controls properties are binary serialized. Next time I open up the form I could just load this this xml file deserialize properties and assign them to corresponding objects. Now the problem is the controls that I have are the custom controls inherited from dotnet ones, and we have a total build process that runs everyday and changes versions of these controls. So we are using simple binary serialization (doesn't include versions). This is fine if you don't have another version of .net framework in gac. What would you suggest here?

    - Windows Communication & Application Instancing in DotNet Good Morning, My problem is 2 fold. First of all, I want to find out a method of detecting whether a prev. instance of an application is already running (I think I already figured this out), and if so, send a message to that already running application (I am thinking by using the WIN32 API Call of "SendMessage"). I am trying to build an application within which I could do instancing/hooking. Basically, I want to be able to build an application that would be able to detect if another instance of it is already running, and if so, communicate with that already running instance, and send a command, and shut its self down. Almost the same behavior that outlook express has... i.e. if you already have outlook express already running and you attempt to lunch the executable again... it doesn't create a new instance of outlook. I currently have a function called PrevInstance() that detects whether or not a prev. instance of the same app is already running.. My only problem now is communicating with that already running instance of my application.

As I understand it (which is not to say I do understand it) I should be able to include a "transfer-encoding:" header of say- gzip, then gzip my content before posting. Since it is a transfer-encoding, I assume any half decent web server should be able to automatically ungzip it before passing it on to whatever app needs to handle it. Is this assumption correct? If so, does .NET support gzip transfer encoding or do I need an external library, program, etc. If external is necessary, where should I look.

    - Why does Microsoft have such a hard time understanding what they say? You know there is a difference between the Microsoft .NET Framework and the Microsoft .NET Framework SDK. Besides the fact that the former is 20 some MB and the latter is some 100MB there is a difference you know. But not according to this page: http://support.microsoft.com/?scid=kb;en-us;306160 This command near the bottom: N:\dotnetframework\dotnetfx.exe /t:c:\temp /c:"msiexec.exe /i c:\temp\netfx.msi REINSTALL=ALL ReinstallMODE=vomus" has not a damn thing to do with the Microsoft .NET Framework SDK. This is a reinstallation of the Microsoft .NET Framework which is NOT the Microsoft .NET Framework SDK as the title of this article says. To me this is like the misunderstanding of Microsoft Outlook and Microsoft Outlook Express. Why does Microsoft have such a hard time understanding what they say? And finally is there a repair for the Microsoft .NET Framework SDK not to be confused with the Microsoft .NET Framework? Thanks. -- George Hester __________________________________ Tag: .NET software development tools Tag: 54012

    - .Net Framework and Sharepoint Server I was just wondering if .Net Framework would interfere with stuff in a Sharepoint Server? Because in our IIS server, we are getting a 404 on a smart client app that we are trying to deploy. We tried 3 other IIS servers (development), and it seemed to work. It is just that one server (Release) which gives us a 404. Any Ideas? Thanks. Tag: .NET software development tools Tag: 54011

    - Screen capture? Under VB6, it was fairly straightforward to get a screenshot. For instance, the following code: Public Function ScreenshotBits(hWnd As Long, Optional compress As Boolean = True) As Byte() Dim bitmap_info As BITMAPINFO Dim pixels() As Byte Dim Size As Long Dim dc As Long dc = GetDC(hWnd) Dim memDC As Long memDC = CreateCompatibleDC(dc) Dim r As RECT GetClientRect hWnd, r ' Prepare the bitmap description. With bitmap_info.bmiHeader .biSize = 40 .biWidth = r.Right - r.Left ' Use negative height to scan top-down. .biHeight = r.Top - r.Bottom .biPlanes = 1 .biBitCount = 32 .biCompression = BI_RGB End With Dim bm As Long Dim ptr As Long bm = CreateDIBSection(dc, bitmap_info, DIB_PAL_COLORS, ptr, 0, 0) Dim oldbm As Long oldbm = SelectObject(memDC, bm) BitBlt memDC, 0, 0, r.Right - r.Left, r.Bottom - r.Top, dc, 0, 0, SRCCOPY ' Copy the bitmap's data. Size = (r.Right - r.Left) * (r.Bottom - r.Top) * 4 ReDim pixels(0 To Size - 1) GetDIBits dc, bm, 0, r.Bottom - r.Top, pixels(0), bitmap_info, DIB_PAL_COLORS If compress Then Dim z As New clsZLib z.CompressByte pixels End If SelectObject memDC, oldbm DeleteObject memDC DeleteObject bm ScreenshotBits = pixels End Function How do I duplicate this functionality in VB.NET? That is, I could import all the API calls and do almost the exact same code, but the .NET framwork abstracts tons of things that were previously the realm of API calls. Is there a .NET way to do this? ~BenDilts( void ); Tag: .NET software development tools Tag: 54003

    - How do I write to a private folder? Hi all, I am trying to write a stand alone C# Console program with .NET framework. The program will create a folder in a existing folder. The existing folder is set with "Make this folder private" and "Encrypt contents to secure data". I tried LogonUser, Impersonate, AddPermission to PermissionSet but none of them work. The error is "Access to ... is denied" eventhough I run the program in the same account that I used to create the folder. I dont have any problem to create to any other folders without the private and encrypt setting. I am using Windows XP, NTFS and the existing folder is created in user profile directory. Please help.

    - documents of MSIL & CLR? Hi, I am a C# developer and want to study deeply about the .NET internals, MSIL and CLR. Where can I find reference documents about them? For example, reference to all operation instructions of intermediate language, and file organization of a .NET assembler. I believe there should be documents about those areas, but could not find them in my MSDN Library(July 2k3) Very thanks, weixiang Tag: .NET software development tools Tag: 53981

When I try to have someone else run another session I get an error message: Error while trying to run project: Unable to start debugging on the web server. A debugger is already attached. Would you like to disable future attempts to debug ASP.NET pages for this project? We are running .dot framework version 1 and using Visual Studio 2002. Has anyone got any ideas or done this.

    - JIT For those of you coding windows Application under the framework you must noticed that forms take a performance hit loading the first time. This is because of JIT, I was able to fix this behavior by using ngen.exe, but then I don't get the same optimization JIT gives me and it is a headache for installations (negen has to be called right after the installation). According to Microsoft, a function gets JIT to native code the first time it is accessed. Is it possible to tell the framework to JIT certain functions at runtime without actually calling the functions? Basically, I would like to pre-JIT some of my functions so they don't experience a performance hit the first time they are called. Is this possible? Tag: .NET software development tools Tag: 53963

    - GetLastError Hi, I'm quite new to the .net framework and try to port some old code to csharp. In my code I have a call to a Win32 API function which returns error information by setting the last Win32 error code. I found a GetLastWin32Error() in the Marshal class which seems to do what GetLastError() did. Can anyone tell me how to get a string from the returned error code? In Win32 API code I used FormatMessage(), in Delphi SysErrorMessage(). Anything similar in the .net class library? thanks, Nick Tag: .NET software development tools Tag: 53962

    - Installation of Visual Studio Addin Hello, I'm actually trying to develop an ASP Parser addin for Visual Studio, and have some problem deploying it. When i try to deploy it on a machine where i didn't compile the project the addin fails to load when visual studio loads. There is an error and it proposes to uninstall the addin. When i scanned the registry while compiling or installing i remarked that the registry was modified only at compil time. So perhaps these registry settings(COM settings), are missing on target machine. Any idea, anyone? Tag: .NET software development tools Tag: 53961
