• Visual C# Set and Get text file properties

  Hi All, My application creates text files. I need to modify, programmatically, the created file's properties (available via righ-click > properties > Summary). Example 1: Set the string "Modified by Jack" into the comment field. Example 2: Get the Revision Number. Thanx, El. What you actually want is to access the Structured Storage, which apparently, is not available via the .Net Framework. Fortunately, this guy ("Mark") wrote a C# class to do it. http://www.hightechtalks.com/dotnet-framework-interop/reading-file-summary-net-186754.html (Warning -- it seems that High Tech Talks' URL rewriter ignores everything in the URL except the ID number at the end. ...Show All

• Visual C++ CRichEditCtrl Problem

  Hi, This is done in VC++ MFC I have created a vector vector<CRichEditCtrl*>RichEditBox; CRichEditCtrl *r1 = new CRichEditCtrl; r1->Create(WS_CHILD|WS_VISIBLE|ES_AUTOVSCROLL, CRect(x1,y1,x2,y2), p, 1); r1->SetEventMask(ENM_CHANGE | ENM_SELCHANGE ); RichEditBox.push_back(r1); With the above code I get n cricheditboxes on a window . How do I navigate within these boxes using Up Down Arrow Keys Pritha Hi, I think you can use "TabOrder" property of these controls, so you can navigate them by "Tab" key. If you want to use up and down arrow you must receive a "KeyPress" message and then set focus on CRichEditBox control. Regards. ...Show All

• .NET Development Error in using .Net Framework 2.0

  Hi, I have installed Visual C# Express edition. The installation seemed successful (no error during the installation of .Net Framework 2.0, Visual C# Express and MSDN Express.

• Audio and Video Development What is the correct way to ignore RequestSample()?

  Hi. I'm making source that has multipule output stream. What should I do when I received RequestSample() for stream1 but stream1 isn't ready to send sample If I wait for stream1 to be ready RequestSample() for stream0 will not be called until stream1 return RequestSample() and cause deadlock in source. If I return RequestSample() without sending any sample by not calling QueueEventWithIUnknown(). It will cause topology to stop. My topology is like this. source->videoDecoderMFT->EVR ->audioDecoderMFT->SAR Thanks. kasumi. RequestSample is expected to turn around pretty quickly. If your Media Source knows that it does not have a sample for Stream1, then it should ...Show All

• Visual Studio Express Editions Convert decimal to fraction

  Does VB have any built-in function to convert a decimal number to a fraction What I need is a way to convert a decimal number into a fraction string rounded to the nearest 32nd. So for example, .375 would be converted to "3/8" or .428 would be converted to "7/16" after rounding. If VB doesn't have this built-in, does anyone have code for a function to do this Thanks...

• Windows Forms A DetailsView Control for Winforms?

  Hello, I have gotten spoiled by the new DetailsView control for ASP.Net 2.0 which encapsulates all of the dirty work needed to switch between viewing, inserting, updating, and deleting for a databound object. Now that I am working on a Winforms application I'm trying to figure out the best practice for handling these rather common tasks. I dislike the look and feel of "in place" editing on the grid view control. Do you typically create seperate forms for inserting/updating/viewing Do you group these items into different panels or group boxes and then play the "hide the unused control" game Do you simply use the same form for these actions and simply disable the textbox (or other editing controls) for view m ...Show All

• Visual Studio Express Editions spellchecker?

  I want to make a spellchecker for a program of mine.  I did a search of the forums and found some code.  I slightly edited it to match my individual use and apparently did something to it to make it not work.  because it ended up throwing the exception and I KNOW I have MS Word. This is the code I used:  Function spellcheck( ByVal text2check As System.Windows.Forms.RichTextBox) If text2check.Text.Length > 0 Then Try text2check.SelectAll() ' Copy everything from the richtextbox to clipboard text2check.Copy() ' Make a Word server object.

• Software Development for Windows Vista FindFirstUrlCacheEntry and COOKIE_CACHE_ENTRY

  Hi, I'm trying to enumerate the cookies on a user's machine and present them to the user along with the associated cookie information. Using the FindFirstURLCacheEntry(Ex) and FindNextURLCacheEntry(Ex) API functions I can do this successfully in Win XP (and in Win XP with IE7 installed so it does not appear to be an IE7 issue). After having looked at the msdn entry for these functions they are listed as supported in Vista but, despite having cookies on my machine and confirming as much by looking in the cookies directory, these functions are not listing out the cookies. Is there a new API to retrieve them or is Vista storing the information differently or are they just flagged differently and it hasn't been documented Any he ...Show All

• Windows Search Technologies Index Global Address List

  Is there anyway to get Desktop Search to index the Global Address List I'm talking about the global address list that I think resides on the Exchange server.  Desktop search indexes my Contacts in Outlook, but those are only the addresses that I have manually added to Outlook.  I also want to index the Global Address List that has all email addresses for the entire company.  I have been trying out Copernic Desktop Search 2 vs Microsoft Windows Desktop Search.  The Copernic Search has an option to index the Global Address List.  This is great because I can just type in a name on the search bar and get an instant phone/email/office directory displayed.  Is there anyw ...Show All

• SQL Server Creating UserInstance DB at application startup

  Hi, I'm developing a WinForms app that will be deployed via ClickOnce deployment and that uses SQLExpress as a local data store. In order to avoid the upgrade DB problem, I'm having my application check for a database and check its version on startup. I am able to successfully create the database if it does not exist, but when I try to connect to the new database, I get a login failed error. However, if I restart the app, it is able to connect to the newly created instance. Here's what I'm doing: If the db does not exist, I connect using this connect string: Data Source=.\SQLEXPRESS;Integrated Security=True;User Instance=True;Connect Timeout=60 I then issue a CREATE DATABASE command and run my table scripts.

• Visual Studio Generating API documentation in visual studio 2005 environment

Thanks a million If you are using .Net 2.0 then NDoc will not work for you since it does not support all the features, plus support and development I believe has been discontinued. Mark. ...Show All
