• Visual Basic How to program software updating from the web

  I would like to add automatic software updating over the internet into the program I have written, but I don't know where to start looking for the relevant information. My program is written in VB.NET 2003 / Windows Forms and we use InstallShield Express 11. I have figured out how to create the web-based setup in InstallShield, and we have got a location to store it on our website. Now I need to find out what code I need to determine if an update is available, download the correct update, exit the program, run the setup and then restart the updated program. If someone could please point me in the right direction to any articles or examples of how this can be done in VB.NET, it would be greatly appreciated. Thankyou in advance. ...Show All

• Visual FoxPro VFP7 COM+ error while calling from ASP.Net 2.0 on IIS6

  Hi, I have an ASP.Net 2.0 application which interop with VFP7 COM+ (using DCOM). It was running fine on IIS5, WIndows 2000. Recently I migrated the server to Win2003 and IIS6 is running on native mode, and I couldn't get the COM+ running, below is the information and hope someone here could help: 1. If the application pool identify set to 'Network Service', I can't even create the COM+ object in the ASP page even though I have granted the 'Network Service' account with neccessary NTFS folder permission. 2. If I change the identify to let say Local System or Administrator, I have no problem to create the COM+ object in ASP page, and VFP codes in the OLEPUBLIC class Init event has actually being processed as well (for example I put a Create ...Show All

• SQL Server Union and Rank have dupliacted records

  Hi Everyone. I have a problem that I could not figure out what to do with it. I have a couple of tables and views. All have the same unique ID. When a user try to do a search on our web site we want to try to look in multiple tables and views, Rank the results and aggregate the results back (remove any duplicates). Part of the search is a Full Text Index search. I created already the following query that seems to be working ok except for one problem, some of the results are duplicated because the Rank is unique. select rank,[key],PL From freetexttable (dbo.items,*,'Key Words') as ft join Items as I on ft.[Key] = I.ItemNumber LEFT OUTER JOIN dbo.IM_90_UDF_IMMasterfile ON ft.[K ...Show All

• Visual Studio Team System Running TFS on Virtual Server

  Hi, Has anyone tried installing TFS on Virtual Server If so is there anythign special i need to do we're going to be instaling so i'd like to know if there's anything else apart from what's published in setup docs. Dellendinho We have also installed TFS in a virtual environment. In our case, we use VMWare Infrastructure 3. I have separate VMs set up for for DT, AT, and Build server. This is all working very well, but keep in mind that the server that's hosting the VMs is a pretty beefy machine (though it is only dual processor) - lots of memory and a SAN for drives. Short answer - it works fine. ...Show All

• Visual Basic Catch SQL connection timeout

  Hi, I have SQL installed on the same computer as Visual Basic. Sometimes when accessing the database file (using the data connection string created from the wizard) my application will receive an exception indicating a server timeout occurred. This only happens once in a while; always will only be the first time I try to run a debug of the application for that day (but doesn't happen every day). If I immediately stop and restart the debugging everthing is fine. I realize this could be a realistic error in the future with the application running on computers and connecting to a true SQL server (i.e. the server is down, network traffic, etc). I am trying to use a "Try...Catch" statement to handle this. My problem is that I ca ...Show All

• SQL Server Display Report Description within Report Body

  Hi all. I wanted to use the Report Properties|Description within the report.I thought it would be something like Globals!Description, but it seems not. Has anyone else found the syntax to use that (or Author) within the body I'm pretty sure that when i tried to do this I was advised that The author and description properties are not available to textboxes. Therefore you need to either hard code the values into a textbox(es) or to add the information to a table and pull it into the report using a dataset. ...Show All

• Visual Studio Team System not downloaded

  Hi guys, in solution control explorer, when i look team build type, why it shows " not downloaded " under colum latest How can i solve this problem Thank you for your help jia This means that the files (.proj, .rsp, Workspacemappings.xml) for your TeamBuildType are only under source control and not in your local dir. To get a copy of the files on a local dir, you have to check out these files. You would want to do this only if you were going to modify these files. You don't need the team build type files locally in order to perform a build. To check out Team build type files, right-click on the appropriate folder/file and select "Get latest version", then select the local dir to download to. Hope that he ...Show All

• Visual Basic Out of Disk Space Exception

  Hello, I have an app that writes Word documents through interop, then assists the user in managing open documents. The app may have one or more instances of the Word Application object open, with one or more active documents per application object. Users are reporting that at times (it seems to be only when more than one instance of the application object is running, but that may be wrong) when the user tries to save or close the document, they get an Out of Disk Space exception. This exception is invalid, because the location that the documents are saved to is a network share with about 500GB free space. I have not been able to recreate the error on my development machine, and so have no clue how to go about handling the exception. ...Show All

• Windows Forms DataGridView Search

  Hi I am using a DataGridView for a timeline - there is a time column starting at 00:00:00.0. I also got a timeslider (Trackbar). When I use the timeslider the correct row in the DataGridView should be selected/highlighted.. Therefore, when using the timeslider the application needs to search the DataGridView for a certain time string. What is the best way to do this Thank you With some more details I might give some suggestion how it can be done. I have worked a lot with the datagridview lately and in general it is advised to work on the datasource instead of the rows and cells of the grid. What is the typical range on the trackbar and how should the value of the trackbar match to a string in the ...Show All

• .NET Development Getting started with simple network game

  Hey guys! I'm pretty sure this is the right forum, but move around as you like :P I have been working on a small 2D game for 2-3 weeks now and it's pretty much done, now all it's need is some network. It should support up to 4-8 players, but I'll properly start out with 2, since the keyboard-key amount restriction is very annoying... I have been looking around at some forums but can't seem to find a good way how to do it.. I have made my own server-client program (tcp), but I need to learn how to use UDP since I need both way communication.. I will properly make a very simple network Pong game to get started.

• SQL Server Unequal operator with GUID

  Hi, Trying to create a conditional split on GUID. As simple as GUID1 != GUID2. According to BOL this is supported: (Quote) The expression set, expression1 and expression2, must follow one of these rules: .... - GUID. Both expression1 and expression2 must evaluate to the DT_GUID data type. (End quote) However, when I do this, I get yhe following message: (Qoute) The data type "DT_GUID" cannot be used with binary operator "!=". (End quote) So, in BOL it's explicitly possible, the error message says not. Of course I can work around it by converting to string, but I need to use this pretty often and would prefer not to convert to string every time. What's the story here BTW, I am on 64-bit ...Show All
