View 2 RepliesI insert a text box, change the parameters to multi line and then pass the string to sql. Users insert comments etc, using line breaks, however because I just pass this as a string the line breaks are not there when they view the text box after input. Example: Here is a well formatted comment. as I typed in the text box today. Inserted in to sql as a string, returns this on select:

View 5 RepliesI am generating a pdf file in asp.net c# using itextsharp. i am not able to draw a horizontal line/verticle line/dotted line.
i tried to draw a line using the following code,i am getting no errors but the line is also not getting displayed in the pdf file
PdfContentByte cb = wri.DirectContent;
cb.SetLineWidth(2.0f); // Make a bit thicker than 1.0 default
cb.MoveTo(20, pdfDocument.Top - 40f);
cb.LineTo(400, pdfDocument.Top - 40f);
cb.Stroke();
What is the problem in the code.Is it because of the position of x y co-ordinates? I had used rough points to know approximate position in pdf,but the line never apears in the pdf file.

I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.
Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's
I have a web app that I am developing at work. I need to be able to take input data and append a text file after (x) number of lines.
My web app is using asp.net with c#
I'm trying to execute a .bat file in my web page when a user clicks a button. The normal command I would run in the command window is as follows. abc.bat 1 Where 1 is project number which is dynamically assigned according to the scenario in the program. Also the .bat file is inside the folder D:Test1. My code looks like this.....
void CreateProjectData( string strProjectId)
{
System.Diagnostics.Process newProcess = new System.Diagnostics.Process();
newProcess.StartInfo.UseShellExecute = false;
newProcess.StartInfo.FileName = @"D:Test1abc.bat" ;
newProcess.StartInfo.Arguments = "abc.bat " +strProjectId;
newProcess.StartInfo.CreateNoWindow = true;
newProcess.StartInfo.RedirectStandardInput = true;
newProcess.Start();
newProcess.Close();
}
When I run the .bat file the data should be generated for project and stored in a database. When I run this in command line it works fine. But when I run the above code in the asp.net web page it executes without any errors but does not store any values in the database. Have I defined the project name, arguments correctly in the above scenario?
I'm using a streamwriter to write a tab delimited file (for import into Mail Chimp), but the last line of the file is always missing a few characters. Doesn't matter what size the List<t> is (its small - about 128 lines)
Code:
protected void WriteTempFile(List<ChimpExportModel> list, out string filepath)
{
Guid UniFileName = Guid.NewGuid();
string path = Server.MapPath("Temp");
string writepath = string.Concat(path, @"" + UniFileName.ToString() + @".txt");
[Code] ....
I've looked at the last item of the List in the debugger and it's just like all the rest. On write, its always cutting off the last characters - which happen to be '.com'. Kinda important. Some posts say to flush and close - tried it. No change. Last characters still AWOL.
ave never used ajax.... I'm currently putting together a little web app that basically calls a program on the server itself (a command line tool) and displays the output to the web page.When the command line tool is run from the command line, it outputs status messages as it does it's thing... as it is now, my page just displays all the output when it's done. What I would like to do is show each line of output on the web page as they happen, just like when run from the command line. I'm guessing ajax is what I need... can anyone point me in the right direction for this specific scenario (user clicks button, output streams to web page as it happens without full page post backs)... a good example would be how ping.exe displays it's output on the command line
