View 4 RepliesI do need a working ASP.NET C# code to replace characters in a string.
My following code works fine but in case of input "a" it gives me an output as "678d", but in case of input "c" the output is correct as it is i.e. "8d"... Here it automatically replaces the rest values too. I can see the code is executing in a step by step process... This results me to get an overloaded output.
{
StringBuilder builder = new StringBuilder();
builder.Replace("a", "6b");
builder.Replace("b", "7c");
builder.Replace("c", "8d");
return builder.ToString();
}
Now, I do need to replace "a" as just "6b" and it should not load the rest values.
i have a string, and i want to replace the last comma with something else. For instance this is my string;
"Monday, December 6, 9:00 PM"
How do i replace that last comma so it can look like this;
"Monday, December 6 2010 9:00 PM"
txtPhoneWork.Text.Replace("-","");
txtPhoneWork.Text.Replace("_", "");
txtMobile.Text.Replace("-", "");
txtMobile.Text.Replace("_", "");
txtPhoneOther.Text.Replace("-", "");
txtPhoneOther.Text.Replace("_", "");
location.ContactWork = txtPhoneWork.Text.Trim();
location.ContactMobile = txtMobile.Text.Trim();
location.ContactOther = txtPhoneOther.Text.Trim();
but it is not replacing and is there any method so that both - and _ can be replaced in single function.

View 3 RepliesI'm having trouble getting a form working with MVC2. As soon as I change the form element to use 'enctype="multipart/form-data"' I get errors when submitting it. The code I've got creating the form is as follows:
[Code]....
With several form text field and a file upload being the only fields. Nothing too complicated!The action method that handles the form submission is as follows:
[Code]....
It's nothing too complicated either. The code that I've commented out would have inserted the image into the database, but I commented it out to see if it was causing the problem, but it's not.The error I'm getting is as follows:
Server Error in '/' Application.
Invalid character in a Base-64 string.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.FormatException: Invalid character in a Base-64 string.Source Error: [Code]....

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927
Obviously something is going terribly wrong here, but I'm at a complete loss as to what it is. The form works fine if I get rid of the multipart bit in the form element, but then of course it doesn't upload the image. I also get the error regardless of whether I've actually selected an image to upload, so it's not the actual image causing the error.

Error: Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. As you can probably tell, the datatypes are: m.UserId = uniqueidentifier l.System_User_ID = varchar(256) I was hoping the casting of one to the other would solve the issue, but it doesn't. How can I re-code this? I see from other forums it would probably be best to set all these fields to uniqueidentifier, but would prefer not to at this stage as it will involve changing quite a bit throughout the whole site!
I am trying to retrieve xml from a small function in my .cshtml page. Its throwing me an error. This however, runs fine in a console/form environment. It takes 3 parameters and 1 exception.
[Code]....
Within my GetXML function it simply applies the parameters to a store procedure. The store procedure returns me my object. From there I can do all the fun stuff in .cshtml. When I manually enter the values from within SQL Management Studio, I do in fact get the right result. Again, when I create a Window Form application - I too get the right result! When it comes down to .cshtml or .aspx pages - I get the conversion failed. I have already tried casting the store procedure uniqueidentifier parameter and it still gave me that error.
