1. I have to select the next invoice number from one table.
2. Then i have to insert this invoice number as it is in three other tables.
3. Then once i have done so i have to go and update the invoice number by +1 (increment by
1). And i have to do this for each row in the datatable.
During this whole period i do not want anyone to access (read or change) that invoice number. We can lock the table or row. Does not matter. How can i do it? I am not suppose to use store procedure. Lock table ... does not work. It is not an T-SQL stmet select invoice number with (readlock) ....... only works while this stement is runned. I want to have the table or row locked until i have done 1,2 and 3rd steps. I have seaching for a stamt in sql which will do this for me! But didnt find anything. All results point me to SP which i cannot use.

My question is a combination of VB.Net creating html code..No Google links to pointless areticles in languages that are not VB.NET, please. If you cannot code it yourself, please don't reply because it's so annoying to ask a question then get pointless, timewasting links just so you can get your points score up.I have a table which has 3 columns - nothing special just simple but its's the row number I am having issues with. Will explain soon.There is a directory with jpg files in it and the number of jpg files increased yesterday by 67, today by 37. Because the picture files come with any filename I have created a Windows app that renames the new files taking the ending point of yesterdays number as the starting point for today..So, each row holds 3 jpg files therefore 67 jpg / 3 = rows (yesterday). First number today is 68. I type 68 into the app I created, enumberating & moving (renaming) the jpg ('hduyhdgu.jpg becomes 68.jpg, suhdos.jpg becomes 69.jpg and so on for each of the new jpgs in that directory. That is done by the simple FileInfo/DirectoryInfo classes. Whilst renaming the photos in numerical sequence it has to write the html in the following form: [code] My Questions are:
1) How to sort out the row numbers so they flow in groups of 3 correctly and not 70, 71, 72, 71, 72, 73, 74, 75..?
2) How to create the table in code that dynamically draws itself with 3 columns (200px each done by CSS) wide and enough rown to hold every jpg in that directory? So, if I moved 5000 jpgs in that directory tomorrow the code will loop through and create the html.
3) If creating the table dynamically as in Q2 above how would I fix the place to draw it? Placeholder? A div is easy (<div 'id="MyTable" runat="server"></div>. In code behind: MyTable.InnerText=.../MyTable.InnerHtml=...) but is it the best idea? [code]
well i am truing 2 make a button when i click it would truncate the data in table , i am trying 2 do this by vb.net 2005.

View 1 RepliesI have a search page in my application where I am searching the database for the records that meet the specified conditions that the user selects. All of this works by creating the dataset, datatable, and dataadapter in the code. I then take a created bindingsource link it to the created datatable and then attach the bindingsource to my datagridview to display the results. Now what I am trying to do is to figure the Mean, Median, Mode and Standard Deviation of the results that were found above. My question is how to I run a select query on the code created table. I have the select query I want to use and when I try to use it in the code it talks about the connection. Now I have a dataset that is part of the project and I have the on just for the search page. Let me know if you need any code samples.

I copy/paste one datagridview from one form to another (different solutions) using two instances of VS 2005.The target form has the datagridview with all settings, including the DataSet and tableAdapter used by the original form. The datagridview also has all old settings. Everything is fine, it works as expected, with one drawback: every time I make any change in the target form surface, VS tells me that the dataset and the tableadapter are not defined and no longer loads the form in design mode giving errors mention that the dataset and the tableadapter are not defined.To be able to view the form surface in Design Mode, I have to edit the form.Designer.vb file and replace the references to the dataset and tableadapter as follows

View 4 RepliesI've tried google a way to sort a table but couldn't get my code working.My program lets the user input enter information such as first name and last name in textboxes, once done they click on update button(so far everything works).On the top right of the form it has a Combobox and it displays a list of all the names of poeple the User inputed... but it shows it in the order the user inputed.I want to have a sort button so that way when the user clicks on "sort" it will alphabetically sort the msql table by last name and reupdate that on the Combobox (most importantly save msql with the new order of names)

View 2 RepliesIn entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ).What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3.
To be more specific ,from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do? To give the ability to create dynamic table fields those steps will not be sufficient. In all 3 steps database , table and table columns are fixed. There is no way that a user can create new tables or columns dynamically. http:[url].... in this post , it shows how to create manual db, tables and etc using SQL but it is based on ADO.NET but I want Entity Manager to do that.
