Hello All
we have a system only accept pdf files with 1.4 version, and so we have to develop a utility to verify a pdf version of a gived pdf file before saving the pdf file into that system.
Currently, we need a pdf library which it could open a pdf file and get the pdf version information. if the library include version conversion function will be a big help for us.
Thanks
Jacob

Hi!
The PDF-Version is listed in the header of the PDF-File. You could just open a stream, read in the first couple of bytes and then compare the version signature with what you want to make sure and that's it.
Would be like 7 lines of code and not library needed.
Regards,
Stevie

Hello Stephan
Thanks you very much!
as you said, the first line of the pdf file kept the pdf version info.
%PDF-1.5, means the version of the pdf file is 1.5.
%PDF-1.4, means the version of the pdf file is 1.4.

Are you sure your service is being run from the bin\debug folder? Also, does your CamToJ2K.dll have any dependencies that might also need to be copied to that location?

Hi,
I made a .net assembly which in which I put an activeX control called DSOFramer. I have converted this in a windows control library and compiled it and installed it in GAC.
This library contains the code to display and edit the office documents similar to DSOFramer control. This same code when tried with DSO Framer and windows application it is displaying the documents. After this,
I tried to put this control on a web form, by using
/* <object id="DSO1" classid="
"DSOControl1.dll#DSOControl1.FramerControl""
width="800" height="300" style="font-size:12;">
<param name="FileUploadURL"
="" value="http://localhost/ServerFileUpload/UploadFile.aspx" />
<param name="MaxSessionUpload"
value="10646" />
*/ tag as above.
But here its not displaying any word or excel file. Could anybody please tell me whats wrong with this and how should I achieve my target. Please tell me if you know. Please.

Hello All,
I'm working on a project where I'll have multiple controls on a Windows form that may get updated when messages are received on a socket being listened on by a worker thread or the controls might get updated from the main thread.
The way I currently understand it is I need to set the controls properties using a delagate if control.InvokeRequired is true.
How could this be done without having to have a delagate method for each control on the form? There are many of them and they all could be updated from the worker thread.
All advice is appreciated.
Thanks.

Try reading up on the SynchronizationContext class. This article[^] might be a good start.

Sir/Madam
I am Final Year Engineering student. I want to get information about connection of computers at different cites.
Actually if I want to computerize a department of any company which have its offices at several cities then what steps I should follow.
Means how I can connect that no of computers in appropriate manner to get desired output.
I want to make it just like railway reservation system through in which if I enter data at same time then database must be able to prioritize data in sequence to enter in database.
Which database & platform or language I should use to code this kind of project.
Thank You

Bugs can neither be created nor be removed from software by a developer. They can only be converted from one form to another. The total number of bugs in the software always remain constant.

I am designing a control that will be manipulated BOTH at run time and design time through a property grid. I have some properties that I would like to hide form the run time property grid as they are not part of my run time interface so to speak (IE: Have no bearing on the run time user experience).
I see this happening already because at run time, when I attach the property grid I am not seeing any of the properties that are in the native 'Design' property category so I know it can be done.
I have tried the simple thing of just putting my properties that I want hidden in that same category but no dice.
I found an attribute called 'DesignOnly' that seemed promising but it does not do what it sounds like it does. MS docs say that it can be used to make a property read only at design or run time, not make it invisible. I found an article in Visual Studio Magazine that seems to indicate different however and have written the author asking him. His article says the following:
"The convenient design-time–only DisplayImageIndex property lets control users pick which image to show. You can apply two attributes to this method's declaration: <category ("design")=""> tells the Visual Studio Properties browser where to list the property, and <designonly(true)> hides it at run time."
Are there any takers out there?
Before you reply here, I already now that you can use the 'Browsable' attribute and hide the property, but this hides is from BOTH design time and run time property grids.

These properties probably have the EditorBrowsable attribute applied with the state set to EditorBrowsableState.Never. In addition, they may also have the Browsable attribute applied and set to false.
You can get more information on the EditorBrowsableattribute here:
http://msdn2.microsoft.com/en-us/library/system.componentmodel.editorbrowsableattribute.aspx[^]
You may want to use EditorBrowsable with the state set to EditorBrowsableState.Never, which states:
The property or method is a feature that only advanced users should see. An editor can either show or hide such properties.

Hi,
As part of an application I'm writing, I created a simple help form. basically, I'm just displaying an html file in a webBrowser component.
As of now, I'm loading the html file from my personal server but obviously that solution doesn't scale for a large number of users (at any rate, not with my home brewed linux-apache setup).
I know there is a way to load html files from the resources into the web Browser control but I have not idea how to proceed. I gave it a shot and included a help.htm as a file resource in my form and then called webBrowser.Navigate("res://help.htm") but it is not working.
Can anyone help please?
Thanks a lot.

I dont think you can do that in a simple way. Here are some ideas:
- distribute your help text as one or more separate files
- include code to turn help resource into one or more local files
- include code that is a simple web server which makes your help resource available
as a set of URL pages.

It is possible, but you can't embed the html resource in a C# assembly. Check out the following article for information:

Hi,
I'm writing an application and I need to load some settings at startup. So before, the creation of the main form, I open a settings file and read the preferences.
The settings are correctly read. So far, so good.
But, when closing and I try to save those settings back to the same file I got an exception : "unable to open "library.xml". The file is being used by another process".
Actually I'm displaying a splash screen (spawn in another thread) before the main form. when I comment out the code for the splash screen, I don't get any more exceptions.
So, I'm wondering? Is there anything wrong about showing a form (the splash screen) before the usual Application.Run(frmMain) statement? Cause basically, the splasher is just another thread in the same process and I abort that thread right after displaying the main form.
Any help is welcome.
Thanks for your time.

I'd prefer showing the splash screen from your Form's constructor or Load event using another thread. Also read the settings from the form's constructor, not the Application class.

Hi,
there is nothing wrong in having another thread showing a splash screen before creating
an instance of your actual application, in fact it is the way I prefer it (create and
show the splash as soon as possible, with the least amount of app code running yet,
and close it as late as possible, i.e. at the end of the main app's constructor, or in
its load event).
But I do have two remarks:
1. if the splash has to share something with the actual app, be careful to close
and syncrhonize things properly (e.g. the settings file, is your splash reading/writing
it ? closing it ? if so, did you establish a lock ?)
2. I did not like the abort you mentioned. You should not abort/kill a thread if there
are softer ways to achieve what you want (e.g. Form.Close, or setting a flag that makes
a loop terminate).

In theory there shouldn't be a problem, but some of the IDE extensions are still in beta.
