Re: How to export pdf data (byte[] format) from SQL database to PDF using C# ?

3-Apr-14 21:36

Apparently, it can be done - in C++ - but it's very complex, since Adobe PDF reader doesn't accept memory directly. See here: http://forums.adobe.com/message/2018299#2018299[^]

I've also seen a suggestion that you should create a ramdisk at runtime, save it to that, and open the file from there - which kinda indicates the level of desperation you need to have to do it.

Basically, I'd go with a "save it as a file in a particular folder and purge the folder regularly" approach, or possibly convert the PDF to HTML and display that.

But there doesn't appear to be a "nice" solution.

No, it's NOT urgent. Everyone here volunteers their time. Questions are answered when we have the chance to, not when you demand it.

Hello everybody!
I have two forms: first form have a listbox1 (lists all members) with a button3_click to put a new member in listbox. the second form have four textboxes to type in properties from new member.
So my problem is how can I move the new member with them properties from form2 to form1.
My try is:
here I initialisize form1 with construct without parameters and second with properties-info for a new member

namespace DateiSchreiben
{
    public partial class Form1 : Form
    {
        public Information info = null;
        public string path;

        public Form1() { InitializeComponent(); }

        public Form1(Information info)
        {
            InitializeComponent();
            this.info = info;
        }

here I click button to getting start form2 to add a new member

public void button3_Click(object sender, EventArgs e)
        {
            //add item
            AddItem item = new AddItem();
            item.Show();
        }

here is caption of form2 "AddItem" I initialsize form AddItem, when I typed in all info (four textboxes) press button1_click in form AddItem and save all infos in class Information which I want callback in form1. How can I do this?!

namespace DateiSchreiben
{
    public partial class AddItem : Form
    {
       public AddItem()
        {
            InitializeComponent();
        }
       public void button1_Click(object sender, EventArgs e)
        {
            //button1 "Ok"
            Information info = new Information();
            info.FamName = textBoxA1.Text;
            info.VorName = textBoxA2.Text;
            info.AFid = textBoxA3.Text;
            info.Key = textBoxA4.Text;


            Close();
        }

Finally I want print the new member in the listbox1 in form1

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

So start by thinking about the task: get a pen and some paper, and do it manually, ignoring a computer.
Work out what processes you need, what data you need and how the processes affect that data.
Write it all down, and then do it again, following the processes and with the data on more paper. When you have an optimal set of data, and a set of processes that manipulate that data, you will have the design specification for your application. Actually coding it is the easy bit!

Afraid so... It divorces the task from the computer, and gets you thinking about it as separate data items and processes, instead of considering implementation details.

Even a tablet "focuses" you on the computer elements of the solution, instead of considering the task as a discrete operation.

Try it! You might be surprised...

Converting US7ASCII data to UTF8

Hello,

I need to convert US7ASCII data to UTF8 or binary without changing the character set.
I just can search the broken data becasue the stored data is not English.

I tried like this :
Select convert(column_name, 'US7ASCII', 'UTF8') From table_name
But that didn't work at all.

Did I try wrong?

Please give me some ideas..
Thanks!
