• .NET Development In C#, what is the difference between System.String and System.string (lowercase)

  This mignt not be the correct forum, if so, I'm sorry about that. I am trying to get a better understanding of the .NET library. I am programming in c# and I see that System.String (uppercase String) and System.string (lowercase string) seem to be the same objects. However they are color coded in different colors. I am guessing that there is a reason, but I cannot seem to find it in the documentation. Can anyone shed some light on this Thanks! Bob Hello All. Bob: You can go to the Environment node in Tools -> Options, and select Fonts and Colors to see all of the different settings for Font, ForeColor, and BackColor for all of the different items in the text editor.

• Visual Studio Team System Missing references..

  Good afternoon, I have a .sln with three projects, two are C# and one is VB. I have migrated the code from VSS and converted from .NET 1.1 & VS2003 to .NET 2.0 & VS2005 with Team Foundation. I open the .sln and all three projects seem to load without issue, however my references for the VB project are missing and I'm unable to add them. Has anyone run into this issue and found a resolution Thank you! Mario, Thank you for the tip! I will try adding the references in the project file using Notepad. I will provide updates as progress is made. Thanks again, Peter ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Making 3d Models?

  Can you make 3d models like characters and stuff in XNA or not...Im new to this whole thing but want to pick up on it so bad. Wings3d is my favorite, although I don't think it exports into file formats that can directly be used (last time I checked this, I was using MDX2, not XNA). There's also Milkshape. I say pick out a few and keep the one for which the interface feels the most natural. ...Show All

• Windows Forms form method Show()

  I have 2 forms. from the button of form1 i display the form2 Form2 f= new Form2(); f.Show(); How can i check if the form2 is dislayed (or has been closed) , so i dont display twice the form2 when i click again the button. I have been searching for a solution to this problem too and wasn't happy with all of the work-arounds on the internet. Public Vairables are bad, disabling buttons is no good for some and keeping and integer counter is complicating a simple problem... Okay, So a good clean solution is to use Application.OpenForms()... For Each shownForm as Form in Application.OpenForms if (shownForm.Name = frmTheScreenIAmCheckingFor.Name) then 'Found you! the pesky is shown up already :-) 'Do somet ...Show All

• SQL Server How to : Truncation : Can i write a log entry whenever data is truncated?

  I'm reading data from a flat file source. If some data gets truncated, i have the option of 'ignoring', 'redirecting' or 'fail component'. What i'd like to do is, to allow the data to be truncated, but i'd also like to write a log entry so that i can know that a particular rows data has been truncated. I've tried 'redirecting' the row to a script component (as transformation), but i don't know how to determine if the error is truncation or not, not only that, i can't redirect the row back to the 'original' flow, which is a derived field column. Any ideas on how to do Cheers. That kind of dilutes the generic nature of the logging infrastructure. now you're talking about raising events for arbi ...Show All

• Visual FoxPro How to create a Word document?

  I wish to convert a memo field into a Word format document. I searched around and found this: oWord=CreateObject("word.application") oWord.Documents.Open("c:\test.doc") oWord.ActiveDocument.Range.Start=0 oword.ActiveDocument.Range.End=0 oWord.ActiveDocument.Range.Text="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" oWord.Documents.Save() It works if the test.doc is already there. How do I create the file using VFP code because the file name should be created by the user himself. Thanks. Thank you both. =filetostr()  does create a word document and it runs fast. But when you try to open it. you got a prompt to convert and need to inst ...Show All

• Visual C++ Odd pre-compiled header question

  Hi folks, I suspect this is an easy one but I can't seem to solve it. A week ago, I decided to reset my VC++ environment settings to the default values. Now, I'm getting errors related to the PCH whenever I try to build a file that's either creating or using precompiled headers. The error if I try to use a pre-compiled header ("/Yustdafx.h") is C2857 -- included file not found in source. If I try to create one ("/Ycstdafx.h") I get C1010 -- end of file while looking for PCH. The compiler helpfully suggests that perhaps I forgot to include #include "stdafx.h" in my source; I didn't. Figuring maybe I'd screwed something up, I reset to default settings once again, created a brand new Windows Forms app and a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Performance issue about UpdateSurface

  Hi all, I'm doing a pretty simple thing but I have too much more CPU load than I expected. Now, what am I doing I need to update a texture from CPU (and draw it) very often (may be about every frame). To do so I create a texture in D3DPOOL_SYSTEMMEM and one in D3DPOOL_DEFAULT (so the first should be in system-memory, while the latter should be in video-memory). I lock the first texture, fill it, unlock it and call UpdateSurface to copy the content into the video-memory texture. Then I use this latter texture to render. (In fact I have two swapping video-mem textures, but for this issue it doesn't matter) Doing so I noticed a quite heavy CPU load on the Present() call. Using a 16MByte text ...Show All

• SQL Server Script task DLL reference w/o being in GAC

  I need to add a reference to a DLL from a script task. But I do not have the ability to put the DLL in the GAC. The DLL is a 3rd party DLL and they do not want to strong name it because that creates a chain effect having to strong name all DLL's that are used in their projects that share the DLL I need to refernce. Ok my question is.. Can i reference that DLL somehow in the script task by manually adding the reference at runtime I found this next snippet of code on the internet, i cant get it to work though.
