• Visual Basic Security

  Hi all I am a relative newbie to .Net and know little about security issues. I have written a VB2005 application that I have installed on one workstation. This works fine. I now need to be able to run this application from another workstation. If I open the shared folder that contains the application from the second workstation and try to run the app I get a security message telling me that I cannot run the app. What do I need to do to allow this to happen I need to keep the application in an identifiable shared folder so that a second app running on the second workstation can call it. Thanks in advance Roy Thompson Hi, I think you would have to enable threading or is it called multi-threading for your applicatio ...Show All

• .NET Development How to use folder path to find pathnames of certain files

  Hello, For a windows application I have created I have used the FolderBrowserDialog to retreive the pathname of a desired folder. Now that I have that pathname I wish to look in this folder for all files with a certain extensions (.html and .htm to be specific), after I find each file I would like to store the file's path name in an array of strings. Also I wish not to look into subfolders, but just at the root of the folder. Is this possible I have looked all over the web and just cannot find anything that will help. I have looked at filestreams and have not gotten anywhere either. Can someone please help me with this matter Thanks, Tareq Ismail Hello, Thanks ahmedilyas fo ...Show All

• Visual Studio Express Editions Movie (Game) Collection XNA Questions

  I wasn't sure if I should spam this into the SQL forums, or here since this sample kit did come with the XNA installation. Either way, hopefully I can find some help here. The Movie Collection looked like a fun little project to tinker with, and I was going to attempt to transform it into a Game Collection program. Sounded entertaining enough, but I've spent the past two hours cursing the gods for the mess that is SQL. Ok, so I'm probably the mess, not SQL, but I can't curse the gods out for the mess that I am :) Here's my issue, I've read everything I can find on trying to fix this problem I'm having. There was some blog entry, a couple articles I found on Google, all of the saming the same ***.. Here's the problem, when I first open up t ...Show All

• SQL Server Dynamic RDLC generation layout problems. Overlapping.

  I am dynamically creating an rdlc file at runtime. I use multiple Matrixes (Matrices ) throughout the report. The problem is, upon viewing, the report isnt rendered the same way as if it was created as design time. The matrices overlap, where as if I create a similar scenerio at design time, they are moved to accomodate the size of the previous element. I have tried many different things as far as the Top and Left attributes go, as well as setting the ZIndex on all of the items to be 1 or 0. Nothing seems to work, they all just overlap. If anyone has any input on this, it would be greatly appreciated. nomer This is an rdlc file that I am having the issue with. Can you notice anything that may cause ...Show All

• Visual C++ Enabling Low Fragmentation Heap fails with GetLastError()=31

  Sorry, another novel here. I'm writing a templated collection class that stores objects by string index as a potentially very wide and deep tree representing all the characters used in all the indices. The class is a rework of one I already have in my project that has been a candidate for optimisation for a while now, and now it's essential because of a significant increase in load through my app. The main problem will be that one of these trees is going to be grown and pruned across a wide range of indices on a very fast basis - probably up to 100-200 times a second at the normal rate of activity, whilst in highly volatile conditions it could go up to 500 or 600 times a second. I ran tests of my original code against std::hash_map ...Show All

• Smart Device Development how to call a control's event?

  In my form_load function; I want to call private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { } how to do that Thank you So you want to call that function from your form’s constructor without explicitly raising the event that causes that function Does it use either the sender or e values being passed in If not it is as simple as: comboBox1_SelectedIndexChanged(null, null); Otherwise you may want to pass in a reference to the calling object and an empty EventArgs object ala: comboBox1_SelectedIndexChanged(this, new EventArgs()); Does this work for you ...Show All

• Visual Studio 2008 (Pre-release) Hide inactive buttons

  By default, buttons with an inactive command are gray. Is it possible to hide them instead Can also set visibility to 'Hidden' which will hide the button but hold its place in the UI (so stuff won't shift). A note on usability however, it is preferable in most situations to 'grey out' a disabled button, especially if it is part of your main user controls, because users get confused when things are there sometimes and not others.  My approach generally is to set opacity to .3 and disable the functionality in the code behind.

• SQL Server Replicating Schema Changes

  Hi there, I'm using Sql 2005 merge replication and I have noticed something, I'm not sure if this is true or not:... My publication is set to replicate schema changes (replicate_ddl = 1). Now, I have noticed that schema changes are only replicated if the current snapshot is valid. Is this right If so why My next question carries on from the first. If I'm about to run a TSQL script on my publisher that will add a column or two to a published table, how do I ensure my snapshot is valid inorder for the ddl changes to be replcated Should I be using: EXEC sp_mergearticlecolumn @publication = <publicationname> , @article = <article name> , @force_invalidate_snapshot = 1 , @force_reinit_subscriptio ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Calculating normals for large mesh with no vertex to triangle info

  I have a mesh of 100.000 triangles where I need to calculate the normals for the vertices. The datastructure, I am using, does not point from vertices to triangles, but only the other way arround. I therefore defined my vertex normals as the sum of the triangles using them, weighted by the triangles size. I simply set all vertex normals to zero and then run through my triangles (when running through them anyway for some other task) and add a triangles normal (weighted) to the vertices it uses. The I run through all vertices and normalize the normals. This is suposed to give me a valid normal for the vertices. I am not much liking waht i see though. The entire terrain is filled with little pyramids. Light ones and dark ones. When I ...Show All

• Visual Basic former issues, revisited: FileSystemWatcher

  My understanding of the FileSystemWatcher is that it can only watch a single directory, and either one file type or all file types (nothing in between). If that is true, I am looking at a different approach, if it is not true, perhaps someone could expand my limited knowledge. In short, here is what I want to accomplish. I have big files being uploaded to our FTP server (located in our office), by various speed IP’s (including dial-up) to over 30 unique folders, and I want them swept into a central location. Obviously I have to be concerned about whether the files have completed their upload before they are moved. I was thinking about an app that has a timed event to check all of the files in each named directory for the “da ...Show All
