In a visual basic.net how do I program a combobox to autocomplete from listeditems in a collection that are filled during the run of the application? Any help offered is greatly appreciated.

I am using VB.NET 2002 and am working in a windows form I am trying to "Crawl" or index a search engine that has a database of just files, not websites. When you perform a search your results will be links to files to download. What i would like to do is create a program to index all files within the search engine's database. My question is how do i go about doing this the most effective way? I can see just trying every possible search string then placing the results in a database and filtering out any duplicate addresses i get, but this seems like a poor method. The restrictions on the search engine are a minimum of 3 characerts, so i can't just put in a "*" or "**…

Hi all I am in the process of trying to use Microsoft Application Center Test to test a web application. I am having problems following the notes in the help file, has anyone come across a good tutorial on how to use this tool correctly? Mike55.

I am writing a program that watches a certain folder for incoming files & then moves those files to another folder. Here's the problem: if I copy a group of files into the watched folder it works fine, but if I move a group of files into the watched folder it doesn't do anything, the event handler never triggers. What is the proper notify filter to use to watch for new files in a folder? I have tried both the Size & LastWrite filters but neither does what I want. Any help would be appreciated. Here is the code I have so far: Imports System.IO Imports System.Diagnostics Public Class Form1 Const watchfolder As String = "c:\checked" Const targetf…

I'm on an ASP 3.0 project right now and need to integrate a library (business) functions for use with this ASP 3.0 web site. I checked the 'Register for COM interop' on the build and put in all the necessary attributes...everything initially worked great...our old ASP 3.0 application was playing happy with a .NET dll. Then we went to make changes. We recompiled and no changes were detected in ASP application - long story short it was still using the old dll. I manually went in with regasm and put in the dll with /u and /tlb arguements and it came back with the successful message for un-registering. From experiance I went to delete the .dll and .tbl (and also th…

Hi! I am trying to to SQL updates with an access database. One of the fields is a Date/Time field, and the problem occurs when I do n ot want to insert a date.

Hi All, Does anyone know if or how it is posible to show or an image or a progressbar while uploading a lage file. I've seached the forum/i-net but didn't find anything usefull :o I'm using VS2005 and tried to hide/unhide an image but with no success. Thanks!

was wondering if there would be any difference between literal values and datatable placed in a session, suppose i have these Session("object1") = "the string" Session("object2") = 100 Session("object3") = True and these Dim dt As New DataTable("objects") Dim dr As DataRow dr = dt.NewRow With dr .Item("object1") = "the string" .Item("object2") = 100 .Item("object3") = True End With dt.Rows.Add(dr) Session("objects") = dt would it differ in performance? (probably will) what could be the best practice? (in general), just curious

How do you get form variables and substitute them into text queries using ADO.NET and also ensure that the common language runtime (CLR) does not confuse your variables for literal strings ? It was easy to do this with classic ASP, but not with .Net Approximately 80% of MySQL ADO.Net examples online have SQL values hardcoded. D Connector/ODBC with Microsoft .NET: http://www.mysql.com/products/myodbc/manual.html#ODBC.NET(C#) http://www.mysql.com/products/myodbc/manual.html#ODBC.NET(VB) Approximately all MySQL ADO.Net text query examples are simple selects and there are very little or no action text query examples. They have all been parametized and it is a m…

i want to create a central resource, custom control? or dll? that will provided a list of clients, and return the result to the program. I have no looked into using custom controls or dll's or yet, however wanted a suggestion as to the most logical direction to head. I want this resource to be located in the one central location, whereby any improvements / changes i make to 'dialog box' will flow through to all other programs that use it, without having to make changes to each of these programs. Thanks for any suggestions.

Is anyone else having memory issues with .NET 2005 Pro? When I first start up the IDE, it takes about 15 MB. When I load my project, it baloons to 85 MB, which, see as how I have 1 GB of memory in this machine, is still ok. However, as I code, the footprint keeps growing, with my machine noticeably slowing. This is all without even running my application. At one point yesterday, I think the "Mem Usage" in the task manager said that "devenv.exe" was taking something like 800 MB. With it that high, I was getting all kinds of errors in VS about it not being able to load files. I shut it down and restarted, and everything was fine. My machine is a Pentium 4 2.8 GHz w…

Hi All, I am looking at using SSL with my site, from what I have read, I need to create a folder in my web site into which all pages that incorporate SSL will be stored. I then need to set the AccessSSL = True property, and then everything should work without any major hassle. My question relates to incorporating SSL into the FTP, I have come across a number of companies that seem to offer the service, but nothing for configuring the FTP with an existing SSL certificate.

Hi. I'm getting some pictures from internet (through http protokol). I'd like to get the time, when they were put on the server, or (even better) when were they created. I cant read file creation property when pictures are allready downloaded, becouse this date/time represents file creation time on my disk (time of download). IE can do it, so I'm sure VB can allso For ex. look url: http://prognoza.hr/aladinHR/

i'm trying to implement 'Process.GetProcesses' on a citrix server however i received the "the application attempted to perform an operation not allowed by the security policy. The operation required the security exception. To grand this application the required permission please contact your syetem administrator" I beleive this is due to the fact that there are several people running off the server, and the 'Process.GetProcesses' command will also receive their processes also? Is there a way to obtain all of MY processes ? Thanks,
