I have been trying to figure out how to use <asp:requiredfieldvalidator> with ValidationExpression but am having a difficult time understanding the syntax of ValidationExpression. I'd like to make sure one textbox's number (1-12) is equal to or higher than the other textbox's (1-12) number. How is this accomplished and what's the syntax of ValidationExpression (hopefully I'm stating the question correctly).

View 1 RepliesI have a SQL database with a table storing three collums. ClientID, StartRange, EndRange.The user needs to add records to a different table - the number being inputted by the user eeds to fall in the range where it is equal to the client he is adding if for. There can be a number of different ranges for a client which where I am falling over, it would be easier if it was just the one range!What is the best way to check this- I was thinking a customer validator method in the code behind?Would I need a Stored Proceedure? or some DataSet Tables and some how parse the ranges?

I have a peculiar situation at hand in which I need to validate a pair of dates in an ASP.Net web app.This is how my page looks like : I have a "From Date" field which consists a set of three dropdownlists ( for Year , Month and Date) I have a "To Date" field which also consists a set of three dropdownlists ( for Year , Month and Date). There is a "Download Report" button on the screen ( which allows a user to download a report for the specified date range) All these six dropdownlists are wrapped in a user control. Now all the 6 dropdownlists have a default "please select" value. When a user lands on the page for the first time , all dropdownlists are set to "please select". The "Download" button is enabled only after valid 'From' and 'To' dates are selected. Now my requirement is that :
When a user lands on the page for the first time , no attempt to validate the dates should be made until he selects all the 6 dropdownlists at least once. When the 6th dropdownlist is selected , the From and To dates should be validated. Once a user has selected all 6 dropdowns once , subsequently on every dropdownlist postback , the dates should be validated. My Issue: What's the best way to track these 6 distinct postbacks ( for each of the dropdowns) before starting to validate the From and To Dates.

How to Validate the Range of Number
[Code]....
i have imported data from excel to datatable but i need to validate port no column which should
allow only numeric value and also i need to check the single quotes and need to replace to double quotes.
it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)

View 2 RepliesI am planning to start up a small business, where i would like to provide my service as a software developer, web applications, or desktop applications etc.I am not sure what Visual Studio license i need to buy,to allow me to do this legally and how much it would cost.to give you an example -
customers provide me with the requirements- i write the application with my copy of visual studio and sell it to the customer for an agreed price, and he or she uses the application commercially , for exampel if its a website i write it, then he/she can publish it via a webhosting company.but i am not sure what license of VS i need to buy which will allow me to do this legally.
I have a license file that I need to access at runtime in order to create pdf-files. After I have created the in memory pdf, I need to call a method on that pdf to set the license, like this:
pdf.SetLicense("pathToLicenseFileHere");
The license file is located in the same project as the.cs-file that creates the pdf, but is in a separate folder. I cannot get this simple thing to behave correctly, which makes me a bit sad, since it really shouldn't be that hard. :(
I try to set the path like this:
string path = @"ResourcesFile.lic";
But it just isn't working out for me.
Edit:
A bit more info. I should mention that this is a web service which returns pdf:s as byte[]. The web service creates the pdf:s, and during this creation process I need to set the license file so as to remove any watermarks from the pdf document. The pdf itself is not saved to disc, and only needs to access the license file once when it is created.
i have developed an app using the devart dot connect control. I have deployed on the server, using iis. However, whenever i try to do anything with the database i get the license not found error.

View 1 RepliesI'm working on a project for a client in which the client owns the source code that I develop. I plan on purchasing and using a 3rd party .NET library in this project. When I purchase the library, I have the right to use it royalty free on as many sites as I like. However, the library uses a license key that must be set in a property before using the library.
What would be the best way to "hide" this license key from the client?
