    - VSS with .NET studio We have purchased Microsoft Visual Studio .NET 2003. We don't have Visual Studio 6.0 on our side. I was trying to install Visual Source Safe, unfortunately I was not able to install the same. I would like to know whether Visual Source Safe and Visio are bundled along with .NET 2003 and if not is it required to buy separately. If its there please let me know the steps to install it. Is it Visual Studio .NET Enterprise edition that includes VSS and Visio? I saw the File > SourceControl > Microsoft Visual Sourcesafe menu in the .NET IDE, but it was disabled. If VSS comes with the Enterprise edition, tell me how to integrate it with the professional edition. Tag: Files used by a process Tag: 67375

    - Please help urgently. Hi all My problem is a little lengthy. But please help me. In my application, ADO.NET DataSet object is not getting constructed in the Web Service Web Method called by the Windows Application passing an ADO.NET DataSet Object as a parameter to the Web Method in Web Service Debugging using the Soap Extensions, clearly shows that the Serialized DataSet is passed to the Web Service, but the Web Service Web Method is not able to construct the ADO.NET DataSet from the Serialized Data. I am hereby giving a brief overview of what I am doing. We're developing a WindowsForms based distributed application. All our WindowsForms clients connect to the business components layers using Web Service. Therefore, the front-end only talks to the Web Service and Web Service calls the Business and Data Layer components. Since the Web Service Layer acts as a gateway between the WindowsForms clients and the business components, We pass all the data using DataSets. Here is the code snippet, private void LoadGroup(string ticker) { //We're creating an object of a stronly typed DataSet EquityPeerCriteriaSet equityPeerCriteriaSet = new EquityPeerCriteriaSet(); //We're setting the properties of the strongly typed DataSet equityPeerCriteriaSet.CriteriaType ="Ticker"; equityPeerCriteriaSet.CriteriaValue =m_ticker; //We're creating the Web Service's proxy object WebReferences.EquityPeerListService.EquityPeerListMgmtService equityPeerListService= new WebReferences.EquityPeerListService.EquityPeerListMgmtService(); //We're calling the web method and passing the DataSet from Dataset DspeerListsSet = equityPeerListService.GetPeerList(equityPeerCriteriaSet); ... ... } Our Web Method looks like this, [WebMethod] [TraceExtension] public DataSet GetPeerList(DataSet dsEquityPeerCriteriaSet) { try { //Creating an object type of the Business Layer EquityPeerListManager equityPeerListManager =new EquityPeerListManager(); ... ... return peerListsSet.DataSet; } catch(Exception ex) { SoapException Se = new SoapException (ex.Message,SoapException.ClientFaultCode,ex.InnerException); throw Se; } } The problem is that, the DataSet object comes as undefined when entering the Web Method. We've also created a SOAP Extension class and debugged the SOAP message chain. The data is present in both SoapMessageStage.BeforeDeserialize and SoapMessageStage.AfterDeserialize stages and we're able to see the data in the log file. This behavior looks very strange. If you can provide a pointer, that would help us a lot. Thanks and appreciate your response. Thanks again. Tag: Files used by a process Tag: 67374

    - accessing VC ActiveX from .NET Hi All, I have created an ActiveX control using VC 6.0. One of the interface implements a method which takes in VARIANT FAR* as the parameter. Iam unable to call this method from C#(.NET 2003) no matter what.. I can call the same method from VB 6.0. I have been bogged down by this problem for quite some time.. I dont have a clue what to do.. The funny thing is that I created a VB stub (again an ActiveX with method taking byref Variant), which calls the earlier mentioned VC activex method with the parameter passed to it. If I call the above VB method from C# using "ref Object" param it works fine!!! Following is the code: C# static void Main(string[] args) { VBActiveX VB = new VBActiveX(); VCActiveX VC = new VCActiveX(); Object OOO = new object(); VB.TryThis(ref OOO); // This Works!!! VC.TryThis(ref OOO); // This gives Exception "Catastrophic failure" } VB6 Dim VC as New VCActiveX; Public Function TryThis(ByRef A As Variant) VC.TryThis(A) ' This Works!!! End Function VC6 short VCActiveX::TryThis(VARIANT FAR* Var) { MessageBox( "What is Wrong???", NULL, MB_OK); return 0; } Similar to this problem, I have a third party ActiveX (VC6) which has a metthod with the same signature(VARIANT *). On calling this method from C# an exception "Type Mismatch" is raised, where as from VB6 it works alright???? So where am I going wrong.. thanx a million in advance Niranjan Tag: Files used by a process Tag: 67373

    - Building My Own DataSource Control hi All, I'm hoping to build my own datasource control, and hoped that someone would point me in the right direction to start. I have already created a class, which accepts a form, a tablename, a connection and a collection of field object (which contain information about which field binds to which form control). I build all this in code, and then the class gets a dataset, binds the controls to it, and allows modifiaction and updates etc. then saves them back to the database. However, I'd like to build a control, which would automate all of this, by getting the fields at design time, and allowing the user to bind the fields and then the user could simply change the connection string at run-time to point to the correct database when deployed. I am trying to kind of replicate the method by which you build bound forms in access. Any pointers to articles, or advice is greatly appreciated. Thanks Alex Tag: Files used by a process Tag: 67365

    - Framework 1.1 on XP Client won't load Framework 1.0 Programs from App.Server Hello there. I hope you can help me out with this one. We have developed a .NET application with the 1.0 Framework. It is located on a Application Server. Windows XP Clients will start the application from the server and run them on their local machine. The local machine has Framework 1.1 installed. THIS DOESN'T WORK. Additionally installing the 1.0 Framework will help (but it is not desired). Also, the same situation with Win2000 Clients will work as well. Any hints on that? Has anyone experienced something similar? Can you guys @Microsoft verify this? Is this a known bug? What can I do? Tnx Heiko Tag: Files used by a process Tag: 67344

    - WebResponse Headers comma delimiting mistake The expires date in a Set-Cookie header includes a comma in every implementation I have seen or read documentation for. However, the CLR's WebResponse Headers collection delimits headers of the same name with commas. I thought I would get around this with the Headers collection method GetValues("Set- Cookie"), but even at that point the headers have already been corrupted by storage as a comma delimited string. Is there a way around this with the CLR? Basically, the WebResponse Header methods Get and GetValues are bugged because they use a comma delimited string to store the headers. I assume somewhere the real headers are available, but probably not available in public. I assume this problem was allowed to occur in the name of code reusability by way of the NameValueCollection. Where can I report this bug? Does anyone know of a workaround or a way to access the headers in their raw line delimited form? Is the CLR source available for perusing? -AB Tag: Files used by a process Tag: 67319

    - What's everyone's beef with Crystal Reports? At one of the VSLive! Orlando sessions there was much disdain expressed for Crystal Reports for .NET by many.

(And I've always wished you could save and reuse formulas, but I understand that's now a feature in v. 10) I like some of the things they've done with the Enterprise version, but I'm skeptical about the licensing costs if I get serious about that direction.

    - Detect encoding of a text file Folks, I have a number of text files in a directory, and I'd like to know what type of encoding they're in. I thought I could just open a StreamReader for each file one at a time, and let .NET determine the encoding (Default, UTF-8, Unicode) - there's a nice constructor for StreamReader which takes a file name, and a boolean "detectEncodingFromByteOrderMarks" which I figured would do exactly what I want - open the file and see if it's a Default (ISO-8859-1), UTF-8 or Unicode (UTF-16) file. Here's my function: public string DetermineFileType(string aFileName) { string sEncoding = string.Empty; StreamReader oSR = new StreamReader(aFileName, true); sEncoding = oSR.CurrentEncoding.EncodingName; return sEncoding; } But that doesn't seem to work - in this case, *all* files are being labelled as "UTF-8", which I *KNOW* is *NOT* true.... Is there any easy way in C# to let it determine the file's encoding reliably? Do I really need to "manually" look at the first three bytes of each file? Any ideas??

I had downloaded a sample WAB program from www.microsoft.com and this program too had the same problem. I want to know if it is a bug or a normal behavior in VC++ and WAB integration.

    - Excel/Outlook interop Hi, All! I'm working on a C# windows service project in witch I'm using MS Excel and MS Outlook automation objects referenced through Microsoft Excel 10.0 Object Library and Microsoft Outlook 10.0 Object Library. On my local computer, calling methods and accessing properties on these automation objects works smoothly. However, when I try running the service, having deployed it on the production server, the execution halts on the first attempt to invoke a method or access a property on one of the automation objects. Strange thing is that no exception is thrown, the service just halts and doesn't seem to get any further in execution. Consider the following code snippet: //-> Excel.Application xlApp; Excel._Workbook xlWbk; Excel.Worksheet xlWst; xlApp = new Excel.Application(); // <-- The call to the Excel.Application constructor returns OK. // However, neither of the following lines of code are ever executed. // The execution of the service just halts, waiting for control to be // returned from the automation object. --> xlApp.AlertBeforeOverwriting = false; xlWbk = xlApp.Workbooks.Add(Excel.XlWBATemplate.xlWBATWorksheet); //<- Just for the record, I've copied the versions of Interop.Excel.dll, Interop.Outlook.dll, Interop.VBIDE.dll from the the project directory on my local computer, onto the production server, in the same directory as my Windows Service executable.

I have the following table in the database: create table t1(f1 int) I already have an instance of SqlCommand (slqCommand) setup with the correct connectionstring and have the following peace of code: -------------------------- sqlCommand.CommandText = "select * from t1"; SqlDataReader reader = sqlCommand.ExecuteReader( CommandBehavior.KeyInfo ); DataRow[] infoRows = reader.GetSchemaTable().Select(); reader.Close(); Console.Write("\n" + infoRows[0].IsNull("NumericScale")); Console.Write("\n" + infoRows[0]["NumericScale"]); --------------------------- It gives me the output : False 255 But the documentation says: --------------------------- NumericScale: If ProviderType is is DBTYPE_DECIMAL or DBTYPE_NUMERIC, the number of digits to the right of the decimal point. Otherwise, this is a null value. --------------------------- - so i figure that this must be a bug (?), or what am I doing wrong? By the way same thing happens when "f1" is of type e.g. "text".

    - Solved: Microsoft Help: IEExe.exe and STA Hi. Thanks for all suggestions. I have finally solved the problem. The System.Windows.Forms.Timer fails because of the UI-operations it executes in my program. So the program crashes when it is being closed. The solution was to replace the System.Windows.Forms.Timer with an implementation of SetTimer and KillTimer. Now it works fine. ... int monitorTimer = SetTimer(this.Handle, 9999, 1000, 0); ... /--- Set timer [System.Runtime.InteropServices.DllImport("user32.dll")] extern static int SetTimer(System.IntPtr hWnd,System.UInt32 iEvent,System.UInt32 iElapse, int iCallbackMustBeZero); //--- Kill timer [System.Runtime.InteropServices.DllImport("user32.dll")] extern static int KillTimer(System.IntPtr hWnd,int iEvent); //--- Timer static static int WM_TIMER = 0x0113; protected override void WndProc(ref Message m) { //--- Check if it is a timer process if (m.Msg == WM_TIMER) { ) base.WndProc(ref m); } br/ peter Tag: Files used by a process Tag: 67213

Hi,

When you try to delete a file that is being used by another process, you get
the IOException: "The process cannot access the file "..." because it is
being used by another process."
Of course...

But which process(es)? is there a way to know which process(es) has/have
opened this file?

Regards,
Sebastien
