I need to create a notification system for my application that will alert the user once new items have been sent to their queue, which is made of up database entries. The latter part of this question may need to be asked in the database forum, but I guess we'll figure that out First, since I haven't created anything like this before, I need some direction on what the best possible solution would be.The notification system should always be running and work independently of the main app. With this requirement, I thought a Windows Service would be best.
The notification itself will just be a quick form that alerts the user. I'm sure most of that will be fairly easy to create. The only issue I'm wondering about is how to constantly check the database and determine a new record has been inserted.Would a windows service have a timer or something that allows me to constantly check?If it does, how would I determine a new record has been inserted?
I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.
I have an installer for my application that makes changes to the registry for better application performance However, depending on the language of the operating system installed this input need changes For example (which is the case itself) Systems in Portuguese the entry is called (Padrao)Systems in English the entry is called (Default) I know I have I change the property "Condition" of the entry I created but I do not know what I have to write in this "Condition" I write within this property to validate that The system is in English or The system is in Portuguese I plan to put the project set two registry entries, one that will be done on systems with English language and other entry in systems with Portuguese language?
View 1 RepliesMy problem is, I have set the parameter to be 150 in the database. and the alert triggered should refer to the parameter value. if the calculation result exceeds the parameter value, it will turn the box to red colour. however, i notice that it only compares the first three number. for example, if the calculation result is 1778.99 it will turn the box red because its first three digit is more than 150. but if the calculation result is 10234.90, it does not trigger the alert. i assume it only takes the first three digit.
Here is the code for this part;
Dim total1 As Label = CType(e.Item.FindControl("total1"), Label)
total1.Text = e.Item.DataItem("inventories").ToString * 365 / e.Item.DataItem("operating_cost").ToString

"When I click on "update page" the control goes to "ActionRepeaterItemBound" on code behind and then to my action.js page and this way I am able to add attributes and use them while calling my jscript function.

i have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?

View 3 RepliesI am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

MSDN: Int32 values are represented in 31 bits, with the thirty-second bit used as a sign bit. Positive values are represented by using sign-and-magnitude representation. Negative values are in two's complement representation. Isn't it true that the representation of positive values using sign-and-magnitude system is identical to the representation of positive values using two's complement system? So shouldn't it have been rewritten as: "Int32 values (regardless of positive or negative) are represented in two's complement representation",
