I have a website that uploads different file types, creates thumbs from the files and saves the file and thumbs to their respective folders. every so often it throws an exception string or binary data would be truncated, Ive never encountered this locally. I have a problem pinning down the circumstances that it happens, I thought it was documents with spaces in the name but that works sometimes as well. This is really bugging me and I need to fix this. The db table fields are long enough, trust me . Has anyone else ever encountered this issue?
I am trying to display a local .html file in a web page. The file uses javascript to display some information about my phone. In the executable, I am retrieving two values out of the registry. I would like to pass these values in a query string (I think that is the correct terminology). Something like file://\Program Files\TestTest.html?type=newtype. I have attempted this with using webbrowser.navigate, but that is giving an unhandled exception when it tries to pass the URI string. Obviously, I have no experience with this and am using the wrong method. There has to be a simple way to open a new webpage in a form and pass it this type of string.
how to implement such a function? I have been attempting to implement this with Visual C# using the .net CF for Windows Mobile.
Not sure if this issue should be posed here, but i try anyway:I have a webpage with a button, button click the webpage will write an image (in binary) to the response object, resulting the user can open or save an image.
Everything is fine in IE in Windows, but in Safari in IPad/IPhone, it is viewed in a seperate browser tab, with the binary image file written as a very long string.In Windows, i know you have to select a program to use to open a new file type for the first time, is this the case in IPad? that i need to select a program?

I am trying to read a normal string from the web.config file. When I try to read a string from the web.config file the application doesnt seem to read it. I set my sqlconnection string in the web.config file. It reads a sqlconnection string but not a normal string.Here is my code:
I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out... I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically.
here is the culprit!
[Code]...
If I had the following in a string or a bit array, what must I populate the bitarray with so that the registry outputs this [above] when written? or, how can I figure out how to do it? I was hoping there'd be a function that reads my string of binary data and transforms it into the real binary format to submit to the RegSetValueEx function in VB6 or other function in VB.Net or C# (this really is a language agnostic question, and the problem exists in all languages; ie: same process).
In asp.net mvc project I am using MYSQlMemberShipProvider. Now I want that instead of reading the connection string from web.config file, it will read the connection string from external file every time. So that I am implementing the cutsom mebership provider class, this class inherits the MemberShipProvider class. But the problem is that if I inherits the MemberShipProvider class then I have to impelment all of its method in my cutsom membership provider class, But I want to use all other inbuilt methods of MemeberShip. What can i do. I only want to add the code like below:
public class CustomSqlMembershipProvider :MembershipProvider { public override void Initialize(string name, NameValueCollection configs) { base.Initialize(name, configs); Connectionstring objProducts = // redaing the connection string. } }
But on compiltaion it is giving me the error does not implement inherit abstract member.
I wanna save this text in my sql db as binary.I wanna retrive it any time I want and read text and view it. How can I do that in c#. Aslo what should my table row type? binary(1000) is ok?
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
My files are stored on a data repository in different formats like .doc,.docx,.pdf,.jpeg,.jpg,.tiff. I want to get those files in binary format(i.e byte[]) so that I can able to see that file to the user using a radbinary image control.I am able to get .jpeg and .jpg files and I can show those to users.But while I am trying to show .doc,.docx,.pdf files I am getting "Not valid parameter" exception.How can I solve this problem? My doubt is that pdf,doc,docx files are having no of pages. So while converting this total pages in to binary data I am getting error. So How can I show first page of .doc,.docx,.pdf files using radbinary image control.Here is my code.RadBinary Image controlis a telerik control,it only deals with binary data.
String or binary data would be truncated. The statement has been terminated. I'm using the following code but some times(not all the time) i get the above error ....
I tested my app locally and it works perfect, but as soon I publish it, upload it to server and try it, on a 100% copy of my local database it throw me a truncate message; now via this msg
that throws me the error query or via sql profiler I got this query:
I have a SqlCommand object on my c# based asp.net page. The SQL and the passed parameters are working the majority of the time. I have one case that is not working, I get the following error:
String or binary data would be truncated. The statement has been terminated.
I understand the error and but all the columns in the database should be long enough to hold everything being sent.
Is there a way to see what the actual SQL being sent to the database is from SqlCommand object? I would like to be able to email the SQL when an error occurs.
Whenever I add more than a very short string to the "description" column in my table I get this error. That column (in the DVD table) is set to NVARCHAR(1000). I can't see what the problem is. I've add the procedure that throws exception below.
System.Data.SqlClient.SqlException was unhandled by user code Message="String or binary data would be truncated. The statement has been terminated." Source=".Net SqlClient Data Provider" ErrorCode=-2146232060
I am using Sql server version enterprise edition 9 on win NT.I have an issue with the stored procedure, when I execute the SP I get an error message "String or binary data would be truncated." In general I know that we get this error when the inserted value is greater than the column length, but in this scenario the SP is failing only the for the section 1 insertion. The same SP contains one more section where we are inserting records in to same table from same source table based on some different condition and it works.I wrote a script in which I copied the section from the SP which has the problem and storing the output of it in an temp table and inserting one by one record using cursors in to the destination table and then it works.I tried with the option SET ANSI_WARNINGS OFF and SET ANSI_NULLS ON, but it did not work. I am sure that it is not failing because of the length of the data inserted.Is there are other configuration that i can set??
I am getting the error: String or binary data would be truncated. The statement has been terminated. when trying to upload an image. What would cause this? my code is:
