• Visual Studio Express Editions graphics question

  I have been asked to make a diagram out of information from a database. I dont know if this is possible but here goes: we have types of phone switches. that are connected via smaller ones BIG --> small --> and smaller Is there a way to have diagrams build via sql and VB Clueless Think of each switch as an object having properties. In actuality such an oject could be described in a structure which describes it including what else it is connected to.

• SQL Server Windows Event Log Notification

  I'm new to SSNS. How would I create an application that would watch the Windows Event Log for a particular Audit Event Source, Event ID (or range of IDs), etc. and send a notification to a subscriber app with that event's data I saw a SSNS filesystem watcher...is there a Windows Event Log watcher too Can I use the built-in .NET one Thanks, Mark More generically,  I have a "master/slave" setup, where I need to send messages (less than 1KB each) from one master to N slaves.

• SQL Server Lookup Task Datatype issue

  Hello: I'm attempting to use the lookup task and i'm running into an issue about incompatible datatypes. The table that i'm referencing in the lookup has a field named DateCreated, and it's DataType is DateTime. But when I hook it up to the Lookup Task, the lookup task thinks it's a DB_Timestamp, so i get an incompatible data type error. What can i do Duane: Thanks for your reply. My problem is not with the dataflow, but with the Lookup Task misinterpreting the Data Type of one of the columns in my lookup table. Instead of being DateTime as the column is set to, the the Lookup task thinks the column is a DB_Timestamp. ...Show All

  I have label1.text = "5/11/2006 2:15:01 AM" and datetimepicker1 with format of dd/MM/yyyy HH:mm:ss when i try datetimepicker1.value = Convert.toDateTime(label1.text ); system threw error saying that the string is not in a correct format plz help thats correct since it will be of an invalid format. generally the format should be everything except the AM part. why don't you just do something like..... DateTime result = DateTime.Now; if (DateTime.TryParse(this.label1.Text, out result)) { this.dateTimePicker.Value = result; } this will try to parse the DateTime value and if it works then it will set the value to the datetimepicker value property.

• Windows Forms 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
