• .NET Development FileIOPermission ACL Question

  Hi, I've got myself very confused about the usage of the FileIOPermission.Demand method. For example; If I supply a path that I do not have "write" permissions to via ACL: FileIOPermission fileIOPermission = new FileIOPermission ( FileIOPermissionAccess .Write, @" \\server\path\path2\path3 " ); fileIOPermission.Demand(); The demand does not fail as I expected. I've search the forum and found the following: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=149239&SiteID=1 I amended my code to no avail. I've obviously got the wrong end of the stick about how this works! I was assuming it worked by looking at the permissions on the folder or file. Does it just evaulate the assembly evidence ...Show All

• Visual C# root node should not be expanded at page load

  Hi.. I have created a treeview in asp.net using c#. But the problem is all the nodes are expanded when the page loads. In Treeview control, when the page loads, the tree should not be expanded. Only when the user clicks on the root node the child nodes should be seen. There are subchild nodes for the child nodes and they should be expanded only when the user clicks on the child node. How to implement this in asp.net using c#. Please help ...Show All

• .NET Development Confused on the setup of VS with SQL Server

  Hi, I have a bit of confusion over what exactly is happening here. I have taken over a project that was left over from a company and I have just got out of school and my experience is more so with Java and Sun(as my University was sponsored by Sun). Anyays, I have a project in VS 2003. It is a web server application(that is many people inside the company can access this program by typing in the url://myprogram/ ..." The web application uses a MS SQL Server Database. Fine and dandy... I can open up VS connect to the database, view the tables and such but cant view the stored procedures. So I asked, and was told to use the SQL Query Analyzer to create and edit my Stored procedures in the database. The list of queries is in a file called ...Show All

• Software Development for Windows Vista Why IVMRMonitorConfig9::SetMonitor can not work

  I have two monitors with a graphic card with two DVI interfaces. In MSDN, it said The VMR-9 supports a maximum of 16 display devices. The interface IVMRMonitorConfig9 determines the display devices on the system. However, its SetMonitor method seems did not work. My code is: CComPtr<IGraphBuilder> pGB; CComPtr<IVMRMonitorConfig9> pMonitorConfig ; CComPtr<IBaseFilter> pVmr; HRESULT hr = CoCreateInstance(CLSID_VideoMixingRenderer9, NULL, CLSCTX_INPROC, IID_IBaseFilter, (void**)&pVmr); hr = pVmr->QueryInterface(IID_IVMRMonitorConfig9,(void **)&pMonitorConfig); hr = pMonitorConfig->SetMonitor(1); hr = pGB->AddFilter(pVmr, L"Video Mixing Renderer 9"); But, the MFC-dialog sti ...Show All

• Visual Studio 2008 (Pre-release) GridViewColumn.HeaderTemplate

  Hopefully someone can help me with this: In the HeaderTemplate property docco on MSDN it says "After a HeaderTemplate or ColumnHeaderTemplate is specified for a GridViewColumn , it cannot be changed." However, doing ListView/GridView column sorting pretty much as per the Avalon ATC team's post resetting the HeaderTemplate does work and arrows appear in the Header as per the post. What doesn't seem to work is the Header's layout being invalidated. Assuming something like < DataTemplate x:Key = " AscHeaderTemplate " > < StackPanel Orientation = " Horizontal " > < TextBlock HorizontalAlignment = " Center " Text = " {Binding} " /> & ...Show All

• Software Development for Windows Vista Unit Testing with Team Foundation

  I have written several custom activities. I would like to unit test them in some manner. What is the best approach for this I am using Visual Studio with Team foundation and the workflow addins. Currently, the way I have been testing them is creating a workflow that just holds the activity, running the workflow with the desired inputs to the activity, and then comparing the output from the activity to the expected result. I have been running this through a console app, but this doesn't allow for the test cases to be added to the test suite built in to team foundation. In addition, if I try and make test cases for the functions that start the workflows, visual studio crashes. Thanks, Amanda Amanda, an ...Show All

• Visual Studio 2008 (Pre-release) VMR9 and MediaElement

  I am trying to use a DirectShow filter in MediaElement, and although it works in WMP it does not work in a MediaElement. The author has suggested that maybe MediaElement requires the VMR9 in renderless mode with a custom allocator-presenter but I didn't know so I am asking :) Also what are my debugging options I have hooked up the relevant error event but nothing fails, it all seems to work, I just see a blank area instead of the expected video. I don't know if it is relevant but this filter is for DVB-T and as I mentioned works (very) well in WMP. Any help appreciated. Thanks Nicholas, but it didn't, I appreciate the reply though - more than I've got from anywhere else ;) I was under the impression that ...Show All

• Visual C++ Warning C4482 - Enums

  Maybe this isn't the correct forum, perhaps if I ask the question this way. Is there anything wrong with the way I am using the enum below FigureNames is simply an enum {jack, jill, etc..}. When compiling, it get the following warning; Warning 2 warning C4482: nonstandard extension used: enum 'Names' used in qualified name c:\Documents and Settings\Steve Jackson\My Documents\MySchool\C++\Assign1\Assign1\Assign1\Main.cpp 282 switch (name) { case Names::jack: cout << "My name is jack!"; break ; } C++ is certainly harder to master than VB, but its popularity continues due to its flexibility and "to-the-metal" code generation.

• .NET Development Circular reference

  Hi, I have a webmethod returning a "tree" but each node has a reference to its parent. But the XMLSerializer doesn't support circular references. Is it possible to return such circular reference types from webmerthods Thanks, Kostadin XML, with its parent-child structure format, doesn't support circular references. What you can do is use the <XMLIgnore> attribute to prevent the XMlSerializer from the serializing that field, then on the client re-build the circular reference. http://msdn2.microsoft.com/en-us/library/system.xml.serialization.xmlignoreattribute.aspx You could also use a dataset as it supports circular references, not through pointers (ByRef), but through PK/FK (int ...Show All
