• Internet Explorer Development IE7 displays my xml/xslt page differently from IE6

  Hi, I have a Web application that works as follows: - An ASP.net page generates an XML string linked to an XSLT stylesheet and sends it to Internet Explorer. - Internet Explorer applies the stylesheet and displays the resulting HTML page in the browser. Everything worked great with IE6 and most of this still works fine in IE7 except for one page. In that page, I return an XML string similar to the following: 1 < xml version="1.0" encoding="utf-8" > 2 < xml-stylesheet type="text/xsl" href="styles/volumetryAdmin.xslt" > 3 <ifinance xmlns="urn:ifinance" auth="0" lang="fr" today="20061109"> 4 <precomps> 5 <precomp id="5& ...Show All

• Visual Studio Express Editions How do I make a custom Control?

  Okay, hopefully I'm phrasing this question correctly. I'm writing a sort of black jack game. I have, in my project, a card class. One of the properties of the object contains the image of the card, which I can use to pass the image to a picture box on a form. This works okay. But what I want to do is actually place the card object itself on the form. How do i create a class from which I can instantiate an object that has a visual element that I can actually drop on a windows form, and possibly add events and so forth... ala a custom control If someone could maybe point me to the correct article. I've been searching, but i don't think I'm phrasing my question correctly. Thank you and best regards P ...Show All

• Windows Forms update datagridview to datatable

  my solution is a winform app that has 3 layers : UI,Bl and DAL. So yn my UI layer i have a winform with a datagridview inside which is feed with a dataview from a datatable and i have a combobox in the same form to filter the datatable , create a dataview and feed the datagridview. The thing is that the user can enter data in the datagridview, which means this data must be updated to datable in order to keep the data, because the user can shot a selectedindexchagend in the combobox so this fire a rowfilter in the dataview and the data shown in the datagridviws changes, so what i want is to keep the data the user enter in the datatable before update the database. but remember i am working in layers, not using datadapters. hope i m cle ...Show All

• Visual Basic Is there a way to change the folder name for project settings?

  Is there a way to change the folder name for the project settings i.e. “My Project” to “MyProject”. The place wher files like AssemblyInfo.vb and others are stored. Our source control implementation does not allow spaces in directory names and this I giving me grief in the VS IDE. One thing missing is that when you click on “Assembly Information” it does not know that the file moved and displays blanks. I know we can edit the files directly but this whole workaround becomes a training issue to users in our environment. IT would be nice to make this configurable in the next release or a service pack if possible J ...Show All

• .NET Development Binary serialization stream/buffering issue.

  Hi there. Take a look at the following bit of code. It's fairly simple. String Message = "Test" ; MemoryStream MemStream; Byte [] Buf; MemStream = new MemoryStream (); new BinaryFormatter ().Serialize(MemStream, Message); Buf = new Byte [MemStream.Length]; MemStream.Read(Buf, 0, ( Int32 )MemStream.Length); MemStream.Close(); Can anyone tell me why "Buf" only contains zeroes after this process is complete It should be filled with the serialized object data, not nulls. --JT http://zhaymusic.com/ Lucian Bargaoanu wrote: After Serialize you are at the end of the Stream, so actually you're not reading anything.

• Windows Live Developer Forums ASP.NET Virtual Earth Mapping Control

  Here's a link to an ASP.NET Virtual Earth Mapping Control that I'm developing. http://pietschsoft.com/product/ve3 The goal of Atlas is to bring a familiar experience to JavaScript development for ASP.NET developers. They have an abstraction layer built that makes JavaScript programming similar to C#. It is actually rather awesome. With my project, the goal is to create an abstraction layer (the PietschSoft.VE3 library) that eliminates the need for an ASP.NET developer to write JavaScript when utilizing MS Virtual Earth v3. As you can see, the goals are similar. The big difference is that my project is specialized for just MS Virtual Earth mapping. And, the reasons I am not using Atlas within my control are: 1) It's in Beta a ...Show All

• Windows Forms Test for Existance of Object

  Using C#, VS 2005, Windows app - on the main menu we have a menu item to open a mileage screen. If the user clicks on the "Mileage" option on the menu, the screen opens as per the code below. However, if they minimize the screen, or lose track of it below another screen and click again on the mileage option, it will open a second mileage screen. How can I test for the existance of the mileage object, and if it exists, simply bring the screen to the top private void mnuMileage_Click(object sender, System.EventArgs e) { Mileage mileage = new Mileage(); mileage.Show(); } Many thanks Mike Thomas you could just do ShowDialog(), instead of Show(), which prevents the user from going back to the othe ...Show All

• Software Development for Windows Vista RPC problem with MSDTC

  Hi everyone, I am having some trouble with the DTC on a client machine and need help to get it working. The problem started while doing some experimenting with the new WCF stuff, but has evolved into a simple client side dtc problem. In a nutshell, I can't get dtctester utility to work.

• Visual Studio Tools for Office Synchronize between Word and SQL Server trough content controls

  I want to create a Word addin that allows our client to create documents such as invoices and contracts in Word 2007. There are three important constraints...... The documents must be centrally stored within a database. The documents must be based on a templated that is generated on information in the same database. It must be possible to (on-the-fly) add 'free text' content controls that are also stored in the database.... For example....
