• 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

• Visual Studio Team System Solution requiring hardcoded path to projects

  I have a master solution that I'm using to build all the dependent projects in our web application. When I use team build to build the solution it fails because the use of the BuildDirectoryPath is throwing off the full paths in the solution file. I could get around this by overriding the BuildPath in tfsbuild.path, but my real question is what would cause my solution to require that the hardcoded paths to the projects exist, rather than rely upon the relative paths For example, here is a sample from the solution file. Microsoft Visual Studio Solution File, Format Version 9.00 # Visual Studio 2005 Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "CompanyName.Common.Global", "D:\IT\Objects\Common\CompanyName ...Show All

• Visual FoxPro Shellexecute on win98 / XP / 2003 server.

  does Shellexec behave differently on win98 than on XP I have a shellexecute command to unzip a zip file. The 'pfiles' folder the zip file resides in is under the folder the application runs in: =ShellExecute(0,"OPEN","unzip.exe","pfiles\01.zip","",1) On XP machines it works fine. On win98 machines it fails because it won't find the pfiles folder. Thanks. Hi Aleniko, Shellexecute shouldn't be dependant where your application is ran from. In other words in any OS I wouldn't trust it'd resolve my current folder and explicitly pass the path. ie: ShellExecute(0,'open','unzip.exe', fullpath('pfiles\01.zip'),0,1) Alternatively you might pass 5th parameter (working folder). ...Show All

  hi every body Is there any way to read ONLY the last line out of a very Big text file in C# .NET Thanks Here's another way to do it. It is fairly unintuitive and I ran into a few surprises, as documented in the code:     public static String ReadLastLine(String path)     {       String retval = "";       FileStream fs = new FileStream(path, FileMode.Open);       for (long pos = fs.Length - 2; pos > 0; --pos) {         fs.Seek(pos, SeekOrigin.Begin);         // Try to detect the linefeed in the file    ...Show All

• Visual Studio Express Editions Sending Page Down to WebBrowser control

  I have a VB.NET program that loads a web age into a WebBrowser window and I want to programmatically page down to a section of the page. I can get the page to load fine, it is the Page Down command that I am having trouble with. I tried to activate the webbrowser then send the {PGDN} with SendKeys method. It works intermittantly. The problem seems to be in getting the webbrowser to be actived before I send the {PGDN}. I have tried things like: WebBrowser1.Focus() Me .ActiveControl = WebBrowser1 active = Me .ActiveControl but I see other controls on my form get highlighted from time to time. If i manually click in the WebBrowser then send the {PGDN} it works fine. I even tried programmatically moving the ...Show All

• Visual Studio Team System creating work - item. is attribute refname just a qualifier?

  hi, i want to create a set of work-items to replace our existing requirements-database. these are 12 classes. therefore i had a question. in the xml-definition of a work-item i do see often the attribute "refname". a value of this attribute is " Microsoft.VSTS.Build.IntegrationBuild". is this just a qualifier or is there more semantics behind this refname if it is just a qualifier it should be possible to define something like this: <FIELD name="CustomerID" refname="ProjectPweb.CustomerID" type="String" reportable="dimension"> <HELPTEXT>something</HELPTEXT> <SUGGESTEDVALUES> <LISTITEM value="None"/> </SUGGESTEDVALUES> </FIELD> is this assumption correct what do i have to consider when usin ...Show All

• Visual C# How to use DllImport with c++ functions that take a function pointer as an argument?

  I'm trying to understand how dll importing in c# works. I've managed to get it working for function F1 shown below, however I want to extend this to a function of type F2, which takes a function pointer as an argument I've look at the example on MSDN, but it is too dissimilar from what i am trying to do and I don't really understand it. Can someone tell me the c# code that will enable me to import the function F2 into my c# program, or point me to a a more basic tutorial than the MSDN help site, because I really didn't find it useful in helping me solve this particular problem. This is the .cpp file that i compile into a dll which my c# program then uses. I have successfully imported F1, but all attempts to import F2 have failed... extern ...Show All

• SQL Server Questions about various DB connection methods.

  Hello All, I am looking to get some guidance and feed back from the community as to the prevalence and usage of the following technologies: ODBC Descriptor support OLE DB support External Linked Server support Data Link support for Data Transformation Services Specifically I am hoping to find out when each technology should be used and the types of applications that use them. Additionally, I am wondering if there are alternatives to these technologies and why they may have been used instead. Any guidance/feed back is appreciated. Thanks, Hi Jay, The best source of information in this case seems to be the SQL Server Documentation that comes with SQL Server 2005. It is also available at the online MSDN http://msdn2.microsoft.com/e ...Show All

• Visual Basic VB6 Variable Name

  I have declaration in one of VB6 projects. Public Class as String When upgraded to .NET, the statement looks like: Public Class_Renamed As String Because, Class is a Keyword in .NET, it has been renamed. My issue is we are converting only the VB components to .NET and not the ASP pages. Since this is a public variable and it is being used by many of my ASP pages, Is there a way that I can use the same variable name in my converted .NET component You can define your variables like this to allow them to avoid Keyword conflicts: Public [Class] As String You will have to refer to the variable in your local .NET code in the brackets for it not to conflict with the Keyword but in the instances of your class you won ...Show All
