As one of my side projects I've been shuffling through the Adobe PDF 1.8 documentation, thinking about how to whip up a useful (if not entirely complete) library to print to PDF. PostScript takes a little bit to get used to but it's not bad.
My latest milestone was finding a way to retrieve a font from the system and it into the output stream (as PDF features embedded fonts). Now most of the major commercial vendors implement partial font embedding (i.e. only embedding the characters that you've used in your PDF document, rather than the entire font). I think this would be a useful addition to my homebrew library, but MSDN and Google are a bit light on documentation on the Font object.
So I suppose my question to you fine fellow programmers is, is there a way to take a .NET framework (2.0) Font object, remove all but a defined set of characters, and then write the remaining bits to a MemoryStream or FileStream? Would I have to do this unmanaged? Would I have to be so desperate as to break the font apart at the byte level in C++ and manually copy the relevant glyph data to the stream?
Please don't bother me... I'm hacking right now. Don't look at me like that - doesn't anybody remember what "hacking" really means?

All you need to is to use regular expressions or wild cards and pass the typed character to the reglar expression that searchs records in the database and your query returns the search criteria
LIKE %John% will search simliar names with John or Jane
|
|
|
|
|
Can I have an example or where i should search for, Please
Thanks for your help

If this is a web app, search here and google for AutoCompleteExtender.
If it is a WinForm, which I don't know, but you should be able to catch the KeyUp / KeyDown / KeyPress event (which ever is suitable), retrieve the text entered by the user from the textbox, perform your search and populate the textbox with the relevant result.

Hi guys,
I created a datagridview to view and add/upadate/delete data from sqlserver...bud it does add everything without checking whether the data exist in the database or not...how can i do this check?
|
|
|
|
|
Are you writing SP to update the data? you can check
select count(*) from db where <condition> and check if it already exists.
Are you trying to update the entire gridview data at once? Can you send the code?

there is an application with .sln only. I need to have the project file, .csproj also. How can I do this?
|
|
|

Open the solution in Visual Studio, create a new csproj file via Add->New Project, then add your source files to that project.

I opened in vs and tried to add new project, but visual C# shows only windows and office types, how can I add a web app as the project?
I created the web app sln by going through File->New Website because file->project does not show web application at all.

I built a custom control 'ChooseBox' that inherits from ComboBox. When I select an item from a choosebox control, the text in the textbox cannot be seen because of the blue selected text color. If I click away, the selected text is there. I can't see anything wrong with my code. I know this is probably a simple q. Here is the code. Can anybody help?

You could override the OnPaint method, and check to see the bounds of the selected item, then redraw the text using a white font after base.OnPaint is done. I don't see any more obvious way to accomplish that, but let us know if you find one.

I cannot seem to figure it out. The default value is not working because it still comes up in bold in the property window.
private System.Collections.ArrayList _Test;
[DefaultValue(null)]
[Editor(typeof(TestCollectionEditor), typeof(System.Drawing.Design.UITypeEditor))]
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public System.Collections.ArrayList Test
{
get
{
if (_Test == null)
_Test = new System.Collections.ArrayList();
return _Test;
}
set { _Test = value; }
}
I have tried....
[DefaultValue("")]
[DefaultValue(-1)]

What is it you want to happen? Not show up bolded in the properties window of Visual Studio? Or not show up at all in the Visual Studio properties window?

I dont want it to show up in bold.

I have a simple site allows someone to register to download a help file. It has 3 pages:
The main page has the form fields, with a button for submitting that has an onclick event.
The code behind page has the onclick code for the button click. Once this processes, it forwards to the download page.
the Download page has a clickable link to download the pdf file.
Simple, right? ... Well the problem is, if the user hits the back button from the download page, the Click event is still active and the registration code runs again, then redirects back to the download page.. so the user hits back again.. and the loop continues... I have ended up with 8-10 copies of a user.
so I guess I need to clear the click event after processing the registration, before the redirect. But I have been having trouble finding information on how to do this? Is there a quick and easy fix that I am overlooking?
thanks
Sam

Why don't you just make a link on the registration page that leads to the main page? So if the user wants to go back, they can click that link.
Admitted, the other solution would be better, but this one is very simple and quick to make.

The easiest way is to redirect your page to itself. That resets the viewstate, so that going back doesn't cause a refresh of the page load that sent the click event to the code behind.

I'm not positive what you mean. How do I get to the download page if I am redirecting back to the default page? i could add a query string and check that, I suppose and then forward to the download page, but it seem like an odd way to move through what should be a straight forward pageflow...
|
|

There are several ways to do it. One possiblity is to set a persistent cookie on the download page. In the page load event of the registration page, check for the cookie, if it is there, send them to the download page. Then if they come back to the registration page tomorrow or next week, they will be sent along to the download page (assuming it is not a secure page).

Hi All ,
I think the solution for this problem is simple.. But I am unable to get one.
Can you please help me .
The Following code Shows an error: Not All Code Paths Return A Value
public TestCaseDataSet.TestCaseDataTable GetTestCaseSimpleFilterResults(List<int> TestCategories, List<int> Printers, List<int> OsAllowed,List<int> runOs, List<int> Platform,List<int> Status, string BeginRunDate, string EndRunDate)
{
try
{
return mngTestCase.Get_TestCases_ByMasterFilter_01_StronglyTyped(TestCategories,Printers,OsAllowed,runOs,Platform,Status,BeginRunDate,EndRunDate);
}
catch (Exception ex)
{
Console.WriteLine("Error" +ex.Message);
}
}
GetTestCaseSimeFilterResults is the funtion that it is happenning for.
Please help me out,
Thanks

Happy Programming!

What gets returned if the catch executes?
Answer that and you have the answer to your question.
|
|
|
|

The reason you're getting this error, is that not all code paths will return a value. The best thing to do is to declare an instance of the return type at the top, with a default value, set that value in the rest of the code, and return it at the bottom.
What do you want it to return if the method throws an exception ? Why do you have a generic try/catch here at all, what errors are you anticipating, and if they are written to the console, who will see them ? What will the rest of the code do if an error is caught and swallowed here, just try to soldier on ?
