 - How to run vsvars32.bat to make its changes persistent? Hi All, I opened a Command window and changed its directory to one that contained a HelloWorld.cs program. I ran "csc HelloWorld.cs" and got: 'csc' is not recognized as an internal or external command, operable program or batch file. I ran "vsvars32" and got: Setting environment for using Microsoft Visual Studio .NET tools. [snip] (which worked because I had previously amended PATH to include "[snip]\Microsoft Visual Studio .NET\Common7\Tools") Of course, if I opened another Command window, "csc HelloWorld.cs" would again give rise to the "'csc' is not recognized" message because the changes made to the environment variables in the first window were made only to the session in which that window was created. I thought if I ran "vsvars32" in Start | Run the changes would be persistent, but that has proven not the case. I used vcvars32 in the Win2000Pro environment with no problems. What is going on here? TIA, Richard Tag: Desktop Icon Tag: 102588

 - Is there a way to force the precision of a decimal variable? If I have a decimal value, say foo: decimal foo = 3; when I serialize that decimal value to XML, I'll get an element like this: <foo>3</foo> If I have a value like: decimal foo=3.00M; serializing to XML produces: <foo>3.00</foo> My problem is that if I have a textbox and a user types in a value of "3", I need to parse it into a decimal variable and end up with 3.00. (Alternately, if there was a way to tell XML serialization to output "3" as "3.00", that'd be fine but there doesn't appear to be any way to do that.) Is there a way to force the precision of a parsed decimal value? Thanks, Doug Harber Tag: Desktop Icon Tag: 102582

 - Best way to study for the MCSD C# .NET Exam It seems that the official book and course for the 70-316 MCSD exam is covering far fewer details than are required to pass the MeasureUp pre-test. Is this really true, and what can I do about it? How can I best fill in all the required details that the MeasureUp pre-test for MCSD 70-316 requires? Does the MeasureUp pre-test cover far more details than the actual MCSD 70-316 exam? Thanks, Peter Olcott Tag: Desktop Icon Tag: 102577

 - Dynamic Data binding Hi, I am looking for some quick advice on the methods I'm investigating.. I have a portion of my program that allows a user to import address data from either an excel sheet, acess db, or a delimited file. What I need to do is set up their data in a specific format that we use without needing to inform the client ahead of time. For instance we need the full name in a column called "Name", but the customer's file might have a Last Name column and a Full Name column. What I'm trying out is to fill a dataset with their data, and pop up a screen that has 2 data grids(one that specifies what it should be, and one with the actual data) and a bunch of check boxes. While the "Name" column in the ShouldBe table is highlighted, they select a column in their data and then click the checkbx that describes their data. For instance name is highlighted and they click the last name column in their data and check the last name check box and the same for first, then click the next button. This is supposed to bind the checkbox title with the column heads so I can concatenate them into the proper column. It is then supposed to move the highlighted cell in the ShouldBe datagrid down one and allow them to proceed, until at the end I have a dataset that is in the proper format, despite its original format. I have figured out how to create a column of combined columns with ADO using the expression property but I'm still learning how to do the rest. If anyone can give me any advice, tell me a better or easier way to accomplish this and point me in a direction to learn how to do so, or simply say you're doing it the best way, I would really appreciate it.(sorry I'm a novice...my first job) Thanks!

 - Serialization error Hi. I have a class A with an attribute of type B that has an attribute that is a collection of type C. In B, the attribute that is a collection of C is marked with the NonSerialized attribute and in A, the attribute that is of type B is also marked with the NonSerialized attribute. class A { [NonSerialized] B b; } class B { [NonSerialized] C c; } class C : IEnumerable { ... public void Add(object o) {} } I save an object of type A with the Configuration Application Block of Enterprise Library, which tries to serialize the object. And there comes the error. The message says that the collection of type C should have an method Add because it inherits from IEnumerable. The collection has the method Add and should not be serialized once it is marked with NonSerialized attribute. If anyone can understand the problem, can you help me? Tag: Desktop Icon Tag: 102553

 - .NET Intranet Zone Permission to Full Trust?? I build installs for our software CD. One of the application is a vendor app and we don't have access to the code. They recently implemented .Net platform. When we received their latest updates, we are having problems with LAN/Network installs. One of the function is to create a pdf document and gives you an option to print. I am getting .NET security errors. One error box has WsPrint.exe as title and throws in an exception. Another message is Microsoft .NET framework error saying application has attempted to perform an operation not allowed by security policy. If I go in Control-Panel-Admin Settings -.NET Framework 1.1 Configuration - Runtime Security Policies, and change the LocalIntranetZone from medium trust to FULL trust, I resolve all of the my issues.

 - Is the Threadpool useless ? I have a problem with the threadpool I can't seem to figure out. If I use ThreadPool.QueueUserWorkItem to queue say 25 work items, I would expect the Threadpool to give me the 25 free threads of the thread pool i.e. execute my WaitCallback method 25 times instantly. However, there seems to be about 0.5 sec. delay in pulling each thread of the queue. Running the test code public void WaitCallback( object state ) { System.Diagnostics.Debug.WriteLine("Thread "+((int)state).ToString()+" started"); Thread.Sleep(10000); } for( int i =0; i<50; i++) ThreadPool.QueueUserWorkItem(new WaitCallback(WaitCallback),i); I would expect the threadpool to instantly give me all available threads thus executing the WaitCallback method 25 times. However, it takes at least 25 seconds for the pool to kick off 25 threads. If you do not get the threads immediately, this in my book would make the Threadpool completely useless for server purposes and any other for that matter. Is this as designed or am I doing something wrong ? Regards Per Millard Systems Architect Copenhagen Denmark Tag: Desktop Icon Tag: 102511

 - Problem with .Net app using 25% cpu Hi! I am developing a .Net app and I have got some problems with the program suddenly using 25% cpu... The strange thing is that my program is not doing anything(as far as I can tell), and the UI is just as responsive as ever, even though it's single threaded (shouldn't it get a little sluggish??), leading me to believe the problem must lie in a thread I don't controll (GC????) . The program will keep using 25% cpu until shutdown, when restarted it can work satisfactory (about 1-2% cpu) for anything between 10 minutes to 10 hours before the problem reappears.

 - Binding a datagrid to a System.Collections member Ok, all I am doing is trying to bind a data grid to an IDictionary. Here goes: Sub Page_Load(sender As Object, e As EventArgs) If Not IsPostBack() Then Call BindData() End Sub Public Sub BindData() Dim Skl As New Hashtable Skl.Add(1, "Visual C#") skl.Add(2, "Visual Basic") skl.Add(3, "Win32 API Programming") dg.DataSource = skl dg.DataBind() End Sub The error I get is: System.Web.HttpException: DataGrid with id 'dg' could not automatically generate any columns from the selected data source. on the line: dg.DataBind() So, is there some special glue when you have to bind a datagrid to a non-relational source such as IList or IDictionary or Hashtable?

 - String stream in VB.NET 2003 (.NET 1.1) I have some libraries that will write to a stream. I would like them to write to a string, which I can then manipulate in memory, rather than to a file. I cannot find documentation for how to get a stream that writes to or reads from a string. Is such functionality available? Thanks! ~BenDilts( void ); Tag: Desktop Icon Tag: 102433

 - Converting Tif to Jpeg problem (Sorry for the double post I just saw the naming required for themanged newsgroup and I need an answer!! Thanks) Hi, I'm writing an application that extract attachment from Exchange, save it in an SQL DB and then display it over the web. Everything works fine for JPG, GIF, etc. However for TIFF file I need to convert them. However my code does not seem to work... I can convert from JPEG to GIF but not from TIFF to GIF or JPEG. For some reason the converted TIFF image appears to become corrupted during the conversion... The resulting JPEG image shows an empty large image holder. If I "re-convert" (or if you prefer "re-save as a JPEG") a second time the image again before displaying it, then it shows a portion of the image but then seems to repeat a "pixel row" indefinetely till the bottom... Any idea has to what I'm doing wrong? Thanks a lot for your help. Here is the code I use: //Converts the bytes extracted from the exchange attachment //Note: I tried using a file instead of memory stream with the same results public byte[] ConvertTiffToJpeg(byte[] tiffImage) { //Creating memory stream with the raw image data System.IO.MemoryStream memStrm = new System.IO.MemoryStream(tiffImage, true); memStrm.Write(tiffImage, 0, tiffImage.Length); //Create an image from the memory stream System.Drawing.Image img = System.Drawing.Image.FromStream(memStrm, true, false); //Get the list of available encoders System.Drawing.Imaging.ImageCodecInfo[] codecs = System.Drawing.Imaging.ImageCodecInfo.GetImageEncoders(); //find the encoder with the image/jpeg mime-type System.Drawing.Imaging.ImageCodecInfo ici = null; foreach (System.Drawing.Imaging.ImageCodecInfo codec in codecs) { if (codec.MimeType == "image/jpeg") ici = codec; } //Create a collection of encoder parameters (we only need one in the collection) System.Drawing.Imaging.EncoderParameters ep = new System.Drawing.Imaging.EncoderParameters(); //Create an encoder parameter for quality with an appropriate level setting ep.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, (long)100); //Convert the tiff image to jpeg and save the result to a new memory strem System.IO.MemoryStream convertedMs = new System.IO.MemoryStream(); img.Save(convertedMs, ici, ep); //Convert the jpeg image back to byte return convertedMs.ToArray(); } -- Martin Rajotte Incycle Software Tag: Desktop Icon Tag: 102428

 - Microsoft.Web.UI.WebControls not found I downloaded a complete DataGrid example, "IssueTracker", for accessing an Access DB with a DataGrid control. Sounded like a cakewalk.

 - Enterprise Library - Asynchronous Logging... I have managed to get asycnhronous logging work for an asp.net application and I wanted some clarification on the method. Normally if the application is logging synchronously it has all the settings for the logging application block in the app.config for the application. But if you want to use asynchronous logging you have to specify asynchronous logging for all logging types in the app.config of the application and then define the extact logging sinks in the app.config of the msmqdistributor.exe (windows service). Is this correct? Seems rather confusing and rather messy - application specific logging information have to be put into a generic widows service that could be used by more than one application on the system. cheers Ollie Riches Tag: Desktop Icon Tag: 102382

I have C# project with an associated deployment project, which creates
a Desktop shortcut. The icon on the shortcut is some plain-vanilla
document, not the app's icon. Where does one tell the project what
icon to use, or why isn't it picking up the app's icon? The app itself
shows the correct icon.

You will need to associate the doc files with your app by modifying the
registry under the HKCR\your ext\Shell\Open\Command key and specifying
your app location for the default value.

My problem is not one of file association. The shortcut to the app itself
displays a piece of paper (with the little link arrow) as the icon. Why is
it not finding the icon that is part of the exe?
