• JonnyAJAX Buffering Images HELP

  Im not sure if this is the right place for this post, if not I apologize in advance this is my first time on the forum. My question is - I am trying to write an Image Viewer program that reads the file paths from the file system and stores them in a list. Then it loads the first 25 images into an Image list(the 25 can be set to whatever I want.). That all works fine. The problem is when you get to the end of the 25 and its time to add more images. It works but is EXTREMELY slow. I cant seem to figure this out and have been playing with it for a while now. Any insight would be appriciated. Heres my code for adding to the buffer - public void vScrollBar1_Scroll( object sender, ScrollEventArgs e) { Thread addThread; i ...Show All

• babarzhr IntellisenseTextbox

• LievenI Publishing in VB Express

  I am new to VB and program development. I have developed a program in VB Express that connects to Access database. It feeds some data onto forms to allow calculations to be done and saved to the database. It also connects to the same database and starts MS Access to access the reports. Although the program works when debugging I encountered a problem with publishing. If i set the setting in project properties, publish, application files, for my .mdb file to data file, the program returns an error message for starting Access, if i set the setting to include, it works to start Access but does not feed data onto the forms. It seems like I need two different settings for one .mdb file. I please need help on how to resolve the matter. ...Show All

• Gurpreet Singh Gill Win Forms Web Services - Batch Processing/Console Apps

  G'day all, I've been developing a Win Forms 2.0 app using Vis Studio 2005 via web services to a central server. The application provides customer information storage as well as part prices and order details. Periodically a user will be required to run a batch invoicing process which will effectively collate orders over a given period and create invoice records for each order. The batch process could potentially take some for clients holding extensive numbers of orders and parts etc. My concern is that users of the system must still be able to continue to use the application whilst the Invoicing Batching is taking place. From my understanding, using web services and singleton design, the next user 'waiting' to utilise the server ...Show All

• Per Bornsjo Custom Cursor, showing up only in...black

  I tried: this .Cursor = new Cursor ( Application .StartupPath + \\Images\\UI\\Cursor.cur ); to get a cursor, this is one from windows by the way, I used one that I wasn't using, so that I could tell the difference, but apparently... on form load, the cursor is black, not the blueish color it should be, it does this with every cursor I try too! Is there a form property interfering.. Languages: C# & VB .NET 2005 The cursor class only supports cursors of type *.cur. Along with that, I think Wang Chi meant it only supports "black" and "white" cursors. as it has been concluded, .NET supports black and white cursors not color. To use color, P/Invoke as suggested ...Show All

• patrick anguet Loading same user control

  I have a scenario for an MDI C# application, in the parent form there will be a datagrid from which a user may select one or multiple records. I will have to grab only the selected specific record cell values and pass it on to anotgher child form. Based on the number of selection the destination form will dynamically genrate the selected values list and a text box comments field next to each value.

I want to load this user control depending upon the number of record selection from the datagrid, for example if five records are selected then I ...Show All

• Jitusj Passing secure parameters / info to client

  Is there any other way to pass parameters to a clickonce application beside via the URL I do not want to pass the user password through the URL for security reasons. Plus, there's a limit to the URL length. The parameters are dynamic and dependent on the user so I can't hardcode them into the application setting. I *could* encrypt the parameter values but is there an alternative solution Thanks Brian for the information. I am already doing the webservice approach to communicate with the server. However, each webservice call requires the username, password, and db connectionstring to authenticate the user. So I need to somehow pass that information from the web app to the clickonce client app (customers ...Show All

  Hey All For a little project of mine, I need to creat buttons from either an ArrayList containing the names of what the buttons should be called or from or from a database table. Depending what was is easiest to understand/do. They all have to be in the same windows form, so that if the ArrayList contains 10 names then there should be generated 10 buttons on load, and if one of the names is removed from the ArrayList then the button should also be removed.
