    - Using parameters in a SQL OleDb provider leads to "must declare variable error" Hi I am using the code below to run a simple query using the SQlOledb provider but for some reason, I get the error "must declare the variable @BamDestination" when the SQL is executed. This works fine if I use the SQL Server provider. Anyone any ideas ? //Using oledb to support sybase as well as SQL server OleDbConnection conn = null; try { conn = new OleDbConnection(connectionString); conn.Open(); string sSQL = @"SELECT MESSAGEDATE, MESSAGEREF, RESPONSE FROM GENERATEDRESPONSES WHERE DESTINATION = @BamDestination ORDER BY GENERATEDDATE"; OleDbParameter [] arParms = new OleDbParameter[1]; string bamDestination = "BAM"; arParms[0] = new OleDbParameter("@BamDestination",OleDbType.VarWChar); arParms[0].Value = bamDestination; OleDb oleDb = new OleDb(); return oleDb.ExecuteDataset(conn, CommandType.Text, sSQL,arParms); Tag: How to build a component so its visible in the Studio "Add Referen Tag: 98646

    - managed C++: from 'array<wchar_t>^' to 'wchar_t*' I try something like: array<wchar_t>^ buf_str = gcnew array<wchar_t>(len); wchar_t* p_buf_str = &buf_str[0]; And although that work in C#, tha doesn't work in C++ ?!? Also, for some reason I cannot declare them on the stack array<wchar_t> buf_str = gcnew array<wchar_t>(len); (without the ^) but I could do thta with other type.. is ther a work around?

    - managed C++ StringBuilder & wchar_t* from some ManagedC++ code I'm writing I would like to call a function like that void myfunction(wchar_t*, unsigned); I would like to avoid attribute, particularly as I import the header, there are plenty of custom types and function and it's much more easy to just call the function (otherwise I rather code in C#, in fact...) I though I could just wchar_t* buf = alloc(n * sizeof(wchar_t)) for(...) { // copy char 1 by 1 } bur certainly there is a faster version? involving some memcpy, maybe internally to the StringBuilder?

    - Correct ways to throw custom exceptions &when to use inner excepti Hi, I've created a custom exception class that inherits from System.ApplicationException (implemented in a similar manner to the recommendations made in the Exception Management Architecture Guide). My question is: Whatâ??s the correct way to throw a custom exception in the following scenario? Example scenario: Custom Exception hierarchy: +---System.Exception | +---Application.Exception | | +---CustomBaseAbstractException | | | +---UtilityEx If client code calls a function in one of Utility's types and the parameters are two empty strings-- Is it better to throw the custom exception like this: Throw New UtilityEx(BAD_PARAM_EX_MESSAGE) OR-- since ArgumentException is the specific "way" to say "I can't use these parameters" is it better to set an instance of an argumentException to the UtilityEx â??s "inner exception" property? Throw New UtilityEx(New ArgumentException),BAD_PARAM_EX_MESSAGE) Should I only use inner exceptions when catching real exceptions or can you also just create one for the sake of specificity even though the runtime has not thrown one?

    - ASP.NET Security Exception Error I'm new tothe ASP.NET framework and my first task is to create a web interface for an n-tier application. I'm getting the following error when trying to authenticate a forms-based login: "The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file." I've seen a number of people posting this error in the newsgroup and have examined the solutions. Some are assuming a technical prowess with .NET that I just don't have yet while others are akin to reading Swahili. Tracing through the program I've found that the error occurs on the line of code currentDomain.SetPrincipalPolicy(PrincipalPolicy.UnauthenticatedPrincipal); and yields the following stack trace: [SecurityException: Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.] System.Security.CodeAccessSecurityEngine.CheckTokenBasedSetHelper(Boolean ignoreGrants, TokenBasedSet grants, TokenBasedSet denied, TokenBasedSet demands) +503 System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet grants, PermissionSet denied, PermissionSet demands) +144 System.AppDomain.SetPrincipalPolicy(PrincipalPolicy policy) +0 [...]..ctor(String userID, String password, Boolean usePassword) in [...]principal.cs:51 [...]Principal.Login(String userName, String password) in [...]principal.cs:45 [...]tryLogin(String userName, String userPassword) in [...]login.aspx.cs:53 ASP.Login_aspx.btnLogin_Click(Object sender, EventArgs E) in [...]Login.aspx:7 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +108 System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +57 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +18 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33 System.Web.UI.Page.ProcessRequestMain() +2112 System.Web.UI.Page.ProcessRequest() +218 System.Web.UI.Page.ProcessRequest(HttpContext context) +18 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication+IExecutionStep.Execute() +179 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +87 If ignorance is bliss then I'm ecstatic right now.

    - WebExceptionStatus.ReceiveFailure Hi, everybody. Do you know, which HTTP response produces WebException with Status == WebExceptionStatus.ReceiveFailure? I get this exception raised in my small C# tool whenever the HTTP server returns HTTP/1.1 200 OK with no more data in the response body. If there are some other data after 200 OK, then no WebException is thrown. Can it be that the reason of WebException in this case is the absence of the response body? Because in RFC2616 it is mentioned that in case when response contains no data the correct HTTP answer code must be "204 No Content". If this is wrong newsgroup could you please give me a hint, where can I receive an answer on my question? Thank you. Sergey.

    - Application Quitting with no Error I'm using Aspects for my middle-tier data access, and on call interception the application quits without error. It's inconsistent and I've found no solid repro. I'm assuming the CLR is encountering an error it can't handle, but I can't reproduce it consistently so it's hard to determine how this is happening exactly. The object is constructed, and then on property access the application quits. The aspect is used in other places (And is executed well over 50 times) before it crashes. It only crashes in one specific class that doesn't do anything special. Any ideas? Does the CLR have a log file I can access?

    - ASP.NET 2.0 ObjectDataSource question Hello all, The ObjectDataSource control uses reflection to create instances of business components and call the appropriate methods to select, update,... data. How can I use the ObjectDataSource control if I don't want to allow it to instantiate the businesscomponents directly but use a ComponentFactory which takes care of creating components. How can I use the ObjectDataSource control with this factory. The code to create the component and obtain a collection of business objects looks somewhat like this. ICustomerComponent component = ComponentFactory().CreateCustomerCompoment(); ArrayList customers = customer.ReadCustomers(); Is this possible with the objectdatasource?

    - HRESULTs Hi, I've been asked to write some code that only logs "serious exceptions" (a client... long story). I'm a somewhat young programmer and started w/ .net so I haven't been exposed to Com and Hresults before. My question is: I know that all .net exceptions have an HRESULT protected property. Is it true that there's a relationship between an error/exceptions "level of severity" and its HResult value? For instance: The HResult for a common error such as System.NullReferenceException is: 0x80004003 (Reflector has the integer value as: 2147467261) The HResult for an exception that signifies serious trouble such as System.ExecutionEngineException is: 0x80131506. Aka 2146233082 Would it be possible for me to define an HRESULT "threshold" and log all exceptions that are above or below such a value? Or is there no relationship between severity and an exception's HRESULT value? I suppose the other alternative is to use multiple exception filters but assuming that my "relationship" assumption is correct the user one if statement would be more simple and scalable. I know the Logging Block in the new Enterprise Library can do this but Iâ??ve been asked to implement a solution in the next couple of days and havenâ??t delved far enough into the Enterprise library to use it in a real project yet.

    - How do I launche browser maximized each time? I am running Windows XP, IE 6.0, and VB.NET, all with the latest service packs. Originally, whenever I would press F5 from VB.NET to start my web application, I.E. would launch full screen (which is 1024x768 on my computer). (I think I had the browser screen stretched to 1024x768 rather than using the Maximize button). Then I changed my Windows XP resolution to 640x480 to see how my web application would look. Then I changed my Windows XP resolution back to the original 1024x780. But now, each time I press F5 from within VB.NET web application, it launches IE at a resolution of 640x480. Regardless of whether I stretch the browser window or use its maximize button, the browser will launch at 640x480 (not maximized) the next time I press F5 to launch my VB.NET web application. How can I make IE launch maximized (or with a resolution of 1024x768) each time I press F5 in VB.NET? NOTE: If I just launch IE manually from my desktop, it DOES start in Maximized mode, so the root cause appears to be within VB.NET not IE. Thanks for your help.

    - How to use interfaces properly... Ok, I have been testing some things and now I have questions about it. I created a dll assembly that contains just one interface (called ITestInterface), which in turn just has one string property called TestName. I built that project and then closed it. Then, I created a windows forms project and added a reference to that assembly (it's named MyInterfaceTest). Now, before I did anything else, I ran the project and a blank form came up. That was as expected. Then I added the "Implements MyInterfaceTest.ITestInterface" line and it added the property code for me. I built the project again and it ran fine. Then I changed the "Copy Local" property on the reference to "false". I ran the project again and it gave me an error: ----------------------- An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module. Additional information: File or assembly name MyInterfaceTest, or one of its dependencies, was not found. ----------------------- Ok, so now I'm kind of confused. Does each application that implements an interface have to have its own copy of the dll that contains the interface? I'm asking this mainly because I'm working on building an app that uses a plugin architecture, and I am having trouble figuring out how to set up references that will work during development, but will also let the plugin developer drop his executable and associated files into the main application's plugins folder without breaking it. Can anyone explain how this should be done? Thanks! Tag: How to build a component so its visible in the Studio "Add Referen Tag: 98582

Even then, the windows service doesn't fully recover. All the static variables (reference types) in the class just loose their referrence. What's going on?

    - Excel in VB.NET form I need to display Excel data in a Windows form, and I also need to be able to update the data in cells, and allow users to enter data. I added a reference to OWC components in my project and I have a form with an AxSpreadsheet control in it. However, AxSpreadsheet is a Web control and I am running into stumbling blocks. Before I buy Alvin Bruney's book on this topic, I would like to know for certain that I can create a user-editable spreadsheet in a Windows form, and save and retrieve the data in xml or xls files. I don't want to proceed down a blind alley when my alternative is simply to use the Excel application itself. Thanks.

    - Simple question on dotfuscator Hello I'm pretty new to dotNet and am concerned that the code may not be secure. I understand we can use dotfuscator to confuse decompilers but am I correct in assuming that an SQL strings etc. used for ADO, or even such things as simple message box headings etc. etc. etc. would have to be left in tact?

    - Documenting .NET Class Usage We have a number of fore 'Helper' classes that are used throughout our application. All code for the application is in VB.NET. I have been asked to produce some documentation which will list usage for particular methods in these 'Helper' classes so that out BA's can assess the impact of any changes to these classes and hence modify their test plans accordingly. This documentation is aimed at our BA's\PM's that don't have VS.NET installed. Likely destination for the results are either a compiled help file or intranet or both. Where on earth do I start?

    - Can a service abort system shutdown? Hi, Is it possible for a windows service to abort a system shutdown? By registering for the shutdown event with the SCM (by setting System.ServiceProcess.ServiceBase.CanShutdownproperty to true), the service is notified of a system shutdown. But the service has only about 30secs to finish processing. Is it possible for a system service to abort the shutdown? (Something like what a windows application can do by handling SessionEnding event). Thanks, Roshan Tag: How to build a component so its visible in the Studio "Add Referen Tag: 98537

    - Debugging Hi, Im running a .net program I have made and all runs fine, but randomly it will reset itself without warning . The program is a touchscreen program and runs full screen forms ( borderless ). My first thought was a memory leak so I have been watching memory usage via the task manager. It seems that everytime I perform an action in the program ( all action use datasets and data fetches or local xml fills ) the memory usage increases by 5mb. As a test I performed about 70 actions with the program and at the end found that the memory usage was up close to 150mb. Knowing that the Garbage Collector should be collecting any memory that is out of scope ( all forms containing the datasets are closed ) I left the program running on the login screen for 15mins. When I came back I was presuming that the disgard memory would have been collected. But It hadnt, strangly enough the only way the mem used would drop was when I minimized the program and a few minutes later maximized it again. What im asking is : 1.) Does it sound like a memory leak ? or am I wasting my time looking for a leak as this is perfectly normal action for a program ? 2.) If its not a memory leak - what could be causing my program to reset itself ? on the initial form I added an onclose check ( yes / no msgbox ) as a test, but when it reset this check doesnt show. 3.) If it is a memory leak how do I begin tracking it ? I have no experience of finding this kind of error, as the usual stop and step into obviously wont work.

    - DataGrid: Read-Only Delay Okay, as a good neighbor, after searching through the different newsgroup posts without anyone with a similar issue, here's my problem... I have a little c# application with two little forms. One of them containing a DataGrid widget/component with two buttons. One for quiting and the other one calls the second form, which is used to collect data from the user that's then added to the DataGrid on the first form. It's a pretty simple setup. The idea is to keep the DataGrid with its Read-Only property set to true, and using the second form to collect the information for the first one. BTW, the second form also has two buttons: one to cancel the operation and the other one to complete it. The issue is that I started noticing that with this setup when I went to add entries to the DataGrid (using the second form) there was a delay of about two seconds while completing the first entry to the DataGrid. All other subsequent entries to the DataGrid were rather quick, as expected. It was just the first entry where I encountered the delay. Well, I'm using a datatable and a dataset, but these are already active by the time I input data. Not knowing what to do, I started playing around, and decided to try the exact operation with the DataGrid's Read-Only property set to false. Now, the delay was gone. Yes, it could certainly be something else also, but without changing anything else the delay was gone. Heck, maybe this is a known issue, but I certainly didn't know about it. Regardless of the implementation, which certainly could have a major influence on this, why would this property affect the speed of adding data to the widget?

    - .NET 2.0 beta and regex regular expressions Hi, I'm porting an app. from .NET 1.1 to .NET 2.0 and unfortunately the existing regexs don't work. Theres no mention of problems or differences with regex in the current beta release of .NET 2.0, I'm just wondering if my original expression was 'broken'? The regex is: Regex hrefExpression = new Regex("href\\s*=\\s*[\"']?((?:[^>]|[^\\s]|[^\"]|[^'])+)[\"']?"); it's purpose is to extract URLs from HTML links. In .NET 1.1 it will take a string like <a href=blah.html></a> and give me a group with blah.html In .NET2 it seems to match everything after the URL aswell. Any ideas? Only thing I found on the net was a guy with the same problem: http://groups-beta.google.com/group/microsoft.public.dotnet.framework/browse_frm/thread/43876377b41545a5/343595f830499738?q=dotnet+2.0+beta+regex&rnum=1&hl=en#343595f830499738 Thanks Jim Tag: How to build a component so its visible in the Studio "Add Referen Tag: 98524
