Generating Alpha Numeric User Ids?
Mar 10, 2011
I would like to generate sequential IDs in the format ZZZ999 starting from AAA001 but this is not for batch insertion of data. I want to issue the ID to users that signup on the website with the next available ID. Mutiple users can signup and should be issued the next available unique Id. I was thinking of storing the last used Id (just one row that is always updated with last issued id) in a table that I can lookup and use to determine the next id and update it. But given that mutiple users can be signing up at the same time, what is the best way to ensure that each user is issued a unique id while maintaining the issue of sequential ID. Will record locking work? I don't think so, as the last issued id can still be read by mutiple users and that it self will generate the same Id which will not work.

I'm looking at some site code on an XHTML doctype and from what I'm seeing the framework is ASP.net. The IDs in the HTML has a "$" in there. For example:
<img id="$ct100templateContent$SectionPanel1$ctl01$ctl02ctl00_templateContent_SectionPanel1_ctl01_ct999img" src="this.jpg"/>
From a W3C semantic point of view the "$" is not valid in an ID or Class. IDs and classes can only contain alpha numeric characters in an XHTML doctype.
Is the the "$" a ASP.net naming convention referencing a web control or template item?

I have a gridview control that has two bound fields. I want to restrict the user's to enter only numeric values in the second bound column. I went into the properties of the gridview control. Selected "Columns" and clicked on collection. The fields showed up.
I selected the field and clicked on the properties. I found DataFormatString property. can I restrict by making changes to this property?

I need to make sure a user can only enter numeric values for my Invoice Amount Textbox. It is a decimal field in my database.
I came across the MaskedEditExtender. It seemed like the solution for the problem. However, say I want to enter an amount of R50.00
The mask is set to 9,999,999.99.
When the textbox looses focus the amount becoomes 5,000,000.99.
Is there a better way that I can achieve this??
Code:
<cc1:MaskedEditExtender ID="InvoiceAmountMaskedEditExtender" TargetControlID="txtInvoiceAmount"
Mask="9,999,999.99" MessageValidatorTip="true" MaskType="Number" AcceptNegative="Left"
DisplayMoney="Left" ErrorTooltipEnabled="true" runat="server">
</cc1:MaskedEditExtender>

I found this code online to generate a password [URL] ....
How do I know this won't generate a word that might offend the user? I remember seeing something in another page about skipping curse words. Is that worth looking into? I could remove s-f-h-u-i-c-t-k from possible characters?

I need to generate small images for certain parts of text. Those will have to fit into the text seamlessly. I know I can not make up for every browser font settings available, but how do I have to check for Linux, Mac and Windows users depending on the user agent? I want to use the right font (of the three "Verdana, Arial, Helvetiva") for the right user agent OS.
So:How do I check for the OS? What do I have to compare to in the user agentWhere can I get the other two fonts. Does the Windows-included Verdana look the same as the one used on Linux (or, is it free anyway? I don't know much about fonts)? Where do I get Helvetica? Is it Mac OS licensed?
Any code examples can be in either c# or VB.NET. I can read both.

I have very similar problem as this: Allowing users to download files - ASP.NET , but in my case I am generating xlsx file with ajax, and on ajax-called aspx page I am using:
[code]....
When this file is generated, control is returned to ajax calling page and from there I wan't to show save file dialog based on this ajax response and allow user to download this generated file. I don't want to save file on disk with ajax called page and then redirect ajax calling page to that file, because of popup blocker in IE. I am using jquery for ajax calls:

I have a Gridview that I am using in a User Control. The grid loads great and my paging buttons that exist outside of the grid itself work properly. When I click my delete button inside the grid, I am getting an invalid postback message. How should I handle this? My control raises one event by the way.

I came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database development tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding.
The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?

I've just encountered an interesting problem in a standard BoundField in a GridView. The field is for EmployeeCode, which is purely numeric, but stored in a character column in the database. The DataFormatString="{0:00000}" attribute on the BoundField doesn't work, as I assume that format is only for numeric values.
To work around this, I had to use a TemplateField, and bind the text value using the attribute Text='<%# PadNumericString(Eval("EmployeeCode").ToString(), 5) %>'. Is there no simpler way of doing this?

how can I allow only alpha characters into a dynamically created textbox? I don't think I can use a regular expression validator for this issue. Unfortunately, I cannot use Ajax for this issue either.

I am very new to Asp.net--I think this should be very straightforward, but it's not working for me. I'm tyring to pass a variable between pages (actually it's from the same page, but same idea) to query a database and fill a grid.
I'm using this line to call the page:
<a href="Webform2.aspx?letter=A">A</a>
and this for the query and grid
<asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="database.mdb" SelectCommand="SELECT [Hyperlink], [Type], [Language] FROM [List] WHERE [Alpha]=@letter">
<SelectParameters>
<asp:querystringparameter DefaultValue="B" Name="Alpha" QueryStringField="Alpha" Type="String" />
</SelectParameters>
</asp:AccessDataSource>
I want it to fill the grid with values where [Alpha] = "A" (passed value) but it fills it with values where [Alpha] = "B", my default value.

I am trying to generate a route using ASP.NET routing, but I only want it to apply if certain values are numeric.
[code]....
Is there anyway to know if {Year} and {Month} are numeric values. Otherwise this routing conflicts with other routes.

I am not sure of the answer, I have created a field in the Database and created a gridview.To show the .9393939393 a couple of decimal in the gridview. I used this format
.ToString("$#.################");
Through out the experiment, I found out that the decimal and the numeric are getting same format, is that right.
