How To Insert Standard(unchanged) Values To The Database Using SQL Data Source
Jul 1, 2010
I am using SQL data source to display existing records from database as well as adding new records to the database.But in VWD 2008 we can insert only those values which have been inserted into the text box,if I try to change the values or text the Insert option gets disabled.I want to allow user to add only specific field values,for the rest I have created session variables and want to use values from these session variables to be inserted into database.

I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).

I was wondering if there are any free/OS resx files for phrases commonly used among websites. For instance, we all use save/submit/retry/cancel/etc. and I'd be surprised if there wasn't a library out there with these standard phrases in multiple languages.

Using sql server and trying to insert decimal values using a ASP.NET C# code. I get the value for hours from a text box through user input and I'm trying to insert it to the database.
strSQLWAUpdate = " UPDATE Project SET WAHours='" + txtWAHours.Text + "' WHERE WAProjectID='" + hidWAProjectID.Value + "' ";
What happens is it rounds off the hours to interger value. So if I insert 22.3 in the text box what i get in the database is 22 and if I insert 22.7 I get 23 in the database. I do not need any rounding but need to get the values as it is. ( that is 22.3 and 22.7 respectively)

I am trying to insert 8 different selected values from a CheckBoxList into 8 different columns of a database. As it now, I am only able to concatenate all 8 selections into a single string in one column. But this is not what I want to do. In my DB I have Column1, 2, 3, 4, 5, 6, 7, 8. Is there any way of getting this done?

I'm just stumped on what to do with this code, I'm just trying to implement a 'no duplicates' catch on my insert customer form, but it just slips through my if statement to the else everytime. This is the source. Also I tried a .Equals with the same results :(

srcUsers.SelectCommand = "SELECT EmailAddress FROM ISSDClients"
srcUsers.DataSourceMode = SqlDataSourceMode.DataReader
Dim reader As IDataReader
reader = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), IDataReader)
emailAddress = FormView1.FindControl("txtEmail").ToString
While reader.Read()
If reader("EmailAddress") = (emailAddress) Then
lblError.Text = "Your Email is NOT Unique!"
'this is where we cancel the update and return an error
Else
lblError.Text = "Your Email is Unique!"
'nothing needs to happen, maybe just tell them that it went through

i'm currently having a nightmarish moment with Sitecore. Basically my issues are two-fold:
1) the first time i added a standard value item to a template, and added a layout setup to it, i was thrilled, since all my items from that template were showing the layout, however now, certain items are now showing no layout at all. I tried doing presentation->layout, reset several times, but to no avail.
2) i added a new sublayout to the standard value layout to another placeholder, did publish on the template (republish everything, publish subitems), then publish on the standard values item again, just in case (should not be needed), i click on all items from the template, and they show the updated layout with the new sublayout (should be good, right?) however, i browse, both live and with preview to the pages and i am still seeing the old layout without my new sublayout.

Is there a standard method for calculating fixed width values for tables in HTML? Right now, I'm working on formatting tables on a web page to be a fixed width, I have a table that's within another table, when testing the page in IE I notice that the alignment of the colon is off as the second picture below illustrates. My intention is to make sure the colons are properly aligned as they are in Firefox and was just curious if the misalignment was due to the settings in the HTML or if it has more to do with how the browser renders the page.
Firefox:
Internet Explorer:
UPDATE: Sorry for not providing any reference code, here's a snippet of the particular section I'm working with.
<div style="width: 1600px; text-align: center; position: absolute; top: 10%; left: 0%;">
<span id="labelInstructions" style="font-size: xx-large;">PAGE TITLE <br><br></span>
<table style="width: 1000px;" align="Center" border="0">
<tbody>
<tr>
<td style="width: 1000px;"><label for="FileUpload1" style="font-size: x-large;">ENTER: </label><input name="FileUpload1" id="FileUpload1" size="70%" type="file"></td>
</tr>
<tr>
<td style="width: 1000px;"><span id="fileUploadError" style="color: Red; font-size: medium;"><br><br></span></td>
</tr>
<tr>
<td style="width: 1000px;">
<table style="width: 1260px;" border="0">
<tbody>
<tr>
<td style="font-size: x-large; width: 800px;" align="right" valign="top">FILE INSTRUCTIONS:</td>
<td style="font-size: x-large; width: 1800px;" align="left" valign="top">INSTRUCTION 1<br>INSTRUCTION 2<br></td>
</tr>
<tr>
<td></td>
</tr>
<tr>
<td style="font-size: x-large; width: 800px;" align="right" valign="top">FILE EXAMPLE:</td>
<td style="font-size: x-large; width: 1800px;" align="left" valign="top">EXAMPLE 1<br>EXAMPLE 2<br><br></td>

I know it's ugly, just a note, this is an ASP.Net generated webpage and I'm setting the attributes of the HTML elements pro-grammatically from the code behind. I sorta inherited this and my employer wants to keep major changes to a minimum. UPDATE 2: When I adjust the inner table width I can get it to align in IE when set to 1377px. For Firefox, the sweet spot for alignment is 1260px.
