View 3 RepliesWhat is the best free Code Generators for ASP.net C#? I know it is opinion based but I would like to have a list and I searched and found a few and some that said they were free but ended up only being a free trial.
Also what is the Best Snippet Tool to add snippets to Visual Studio 2008? I can not get the one I found to work since I am using a Server as my Development machine.
I am trying to find a code snippet that reads a sql server db and retrieves an image from a table and converts it into a thumbnail image. I'm looking for VB.Net code that does this and I can't find anything.
View 23 RepliesI have written the code below to generate an XML document and it works a charm however the smallest snippet of code is causing me a major headache:
SNOMlabel.text += 1
For some reason this is doubling up and SNOMlabel equals 2 i have debugged the code on this line and it appears to be something to do with when it leaves the Sub btnSave_Click and enters and returns from CreateBookNode, CreateBookNode2, CreateBookNode3.
Code:
Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click
' Name of xml file to create
Dim subs = SubscriberID.Text
Dim name2 As String
Dim fdate As String
Dim length As Integer
length = Len(Page.User.Identity.Name)..........
I did some search but nothing is really useful in my case.
I want to inherit the DataControlField (System.Web.UI.WebControls) to be able to carry two label controls and then I want to color the two labels to get some sort of conditional formatting, I've got the conditional formatting part but how can I customize this class?
Where in my class should I define the two label controls?
How would I override the CreateField method?
P.S: I know I can accomplish this, in XHTML Markup, but I have so many columns that it would not be appropriate to include those markups in the page markup. Therefore I'm doing that in the CodeBehind page.
EDIT:
public class MyField : DataControlField
{
public MyField()
{
}
protected override DataControlField CreateField()
{
// What to put here?
}
protected override void CopyProperties(DataControlField newField)
{
((CalendarField)newField).DataField = this.DataField;
((CalendarField)newField).DataFormatString = this.DataFormatString;
((CalendarField)newField).ReadOnly = this.ReadOnly;
base.CopyProperties(newField);
}
public override void InitializeCell(DataControlFieldCell cell, DataControlCellType cellType, DataControlRowState rowState, int rowIndex)
{
// Call the base method
base.InitializeCell(cell, cellType, rowState, rowIndex);
// Initialize the contents of the cell quitting if it is a header/footer
if (cellType == DataControlCellType.DataCell)
InitializeDataCell(cell, rowState);
}
protected virtual void InitializeDataCell(DataControlFieldCell cell, DataControlRowState rowState)
{
}
}

I try to minimize <% %> code placing "{" symbol on the same line as it's condition (java-style). Html layout looks more clear to me after that.
Do you apply C# formatting rules to <% %> html injections "}" should be on a new line or manage layout in different way?
I am displaying a money values in a gridview. Is possible to use inline code to set the decimal places to two? Would like to do it inline instead of in the C# code behind if possible. Database table column [Rate] is datatype money.

I have an annoying problem with Visual Studio 2008.
When I run the "format code" command ("control+k, control+d") -- it will insert a carriage return. How do I get it to stop doing this?
For example:
<label for="shipCompanyName">Company Name:</label>
undesirably becomes
<label for="shipCompanyName">
Company Name:<label />
I developed a web app and it contains a portion where i populate combobox using an xml file. Now I am required to develop WPF app that does the same thing using the same xml file.
My question is this: Can I reuse the code snippet as shown with some modifications? How do I modify it? I understand I cannot use .DataTextField .DataSource and .DataBind since I cannot use the System.Web namespaces

I use the above code to return records from database. The above snippet would run in web application which expected to have around 5000 visitors daily. The records returned reach 20,000 or
over. The returned records are viewed (read-only) in paged GridView.
Would it be better to use DataReader instead of DataTable?
NOTE: two columns in the GridView are hyperlinked.
i used Ajax Editor in Sevral web pages in som pages the buttons of ForColor and BackColor dont show the Color Palent i dont know if it has any special properties or not.

2. How do I change the font on my Gridview printout?
I am a very new (and green) C# .NET and ASP.Net programmer ...
I want to show just a part of a string for example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
Just a: "Lorem ipsum dolor sit amet, consetetur sadipscing..."
Which method can I use to do that?
I've got this much working fine:
Protected Sub GridView2_DataBound(ByVal sender As Object, ByVal e As System.EventArgs)
If GridView2.Rows.Count > 0 Then
Button1.Visible = True [code]...
I SIMPLY want to show a line of text on the page: "This zip code is not in our database..." in addition to the "Else" statement of "Button1.Visible = False"
Does anyone have a recommendation of a link(s) that provides a variety of color schemes either to be set manually or through a file for VS.NET 2008? For example instead of the default, white background with blue and black letters (VB.NET), etc. I want to see some contrasting black background color schemes or other combinations?

View 1 RepliesHow to convert Hexacode(#669933) into images(.jpg).
View 1 RepliesWe have a service that generates a report (using word templates and a 3rd party library), and then returns a string in HTML. While this HTML isn't great - its formatted correctly in this string. We want this HTML to show up on a page - format intact. What we currently have done is set an ASP.net Literal's text element to this string. While this works, I have noticed that it has reformatted the HTML string slightly. For the most part, it looks like it generated a bunch of new CSS classes, and a new style element in the HTML. This HTML does not exist in the string thats being returned. I could filter all of this back out, but wonder if there is a better way. I assume that the Page itself is altering something. What is the best way to display this raw HTML back to the user? I can't directly use a Response.Write(string), because this page does have a few other controls on it.
