Hi
.Net framework itself provided you with Word library (In reference COM Tab you can see Microsoft Word Object Library) this should help out you to work around Word applications.

Thanks

Thanks for the reply

The Word Library only contain version 12, witch is Office 2007. If I compile my application with that library and deploy it on a machine with Office 2003 I get this error:

System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Office.Interop.Word, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

So I need a way to compile my application with Microsoft.Office.Interop.Word, Version=11.0.0.0

Thanx

OK., when you add the reference into your project you will see some DLLs like

WORD
VBIDE
MICROSOFT.Office.Core

While you create setup you need add that library as part your setup and there you will see one DLL called MSO.DDL go to the properties and in Register Property select "vsdrfCOM" and build your setup.

This you no need to have any MS Office at your deployment PC. Please let me know if you havve any hiccup.

Thanks

Hello

Thanx for the help, im a bit in the blue here...

I did what you sad, importet the reference, created a new setup project. Changed the setting under register property to "vsdrfCOM". But when I try to run it on the deplyment PC I get this error:

"Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClass' to interface type 'Microsoft.Office.Interop.Word._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00020970-0000-0000-C000-000000000046}' failed due to the following error: Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED))"

Any ide what could be wrong?

CreateHandle() error on an Overriden Tooltip for the DataGridView [modified]

Hello,

This will be a pretty long message so please bear with me, and thank you in advance for your help.

For the DataGridView, we needed to disable the ToolTip of the cells for all the columns EXCEPT for one column. And we wanted the ToolTip for that specific column to always show (and not hide after a certain amount of time).

My understanding is that the ToolTip of the DataGridView cannot be exposed, and therefore we had to do a work around. What we did was to create a class that extends the ToolTip and also a class that extends the DataGridView. The new tooltip class, named ManualToolTip, is then instantiated in our extended DataGridView class. (Note: there are other reasons for extending the DataGridView, but extending the ToolTip was done solely for this purpose.) Now, doing this created a lot of problems, I will not copy paste some code snippets and the error that we are getting.

My guess is that I am not understanding the ToolTip correctly. It could be that it is creating and disposing differently than I thought. Could it be that a separate ToolTip instance is created per cell in the table? And does it Dispose when you do a Hide? Well, I'm really just guessing. I need help! Or, at the very least, direction.

Thanks in advance!

what do you mean insert the numbers?

you are writing base on Console or Windows ?

here is just a hint because I don't know what you are doing!!!

for Console

use Convert.ToInt32(Console.ReadLine());

and I suggest you to get a C# book!

Hi,

I suggest you buy an introductory book on C# and work your way through it.
In my experience nothing can replace the first book on any language you want to learn.
Especially if it is the first programming language you are getting in touch with.

I'm trying to venture into making a class, but I'm still a bit dopey in the regard and still don't have everything perfectly understood. Here's what I have.

public void write(IntPtr address, byte[] value, UIntPtr bytes)<br />
{<br />
   IntPtr bytesWrote;<br />
   Process[] processList = Process.GetProcessesByName(hProcess);<br />
   WriteProcessMemory(processList[0].Handle, address, value, bytes, out bytesWrote);<br />
}

But, when I actually make use of it, I still have to cast my stuff and basically write it like this. Whys this?

write((IntPtr)0x10036FA, new byte[] { 0xC6, 0x00, 0x8A }, (UIntPtr)3);

but I was hoping for something to the effect of

write(0x10036FA, (is there a cleaner way to do this?)new byte[] { 0xC6, 0x00, 0x8A }, 3);

are ints. Ints != IntPtr's.

As the error message you'll get states, "Cannot implicitly convert type 'int' to 'System.IntPtr'. An explicit conversion exists (are you missing a cast?)".

Generally something is not given an implicit coversion if it's deemed unsafe. Forcing the use of an explicit cast ensures you know that the cast is happening.

if you don't want to have to cast then pass in an IntPtr ... one of the constructors on IntPtr takes an Int Smile | :)

IntPtr ip = new IntPtr(3);

Good Morning,

I developed a web base project with different languages in c#. I used "Resources" to save different language variable. I am just wondering that can I use same technique in a desktop base application. I need it because I am going to develop a desktop base software in Visual Studio 2005. This software is a multi language software. User should have facility to choose desire language then whole software should change to that selected language. Any Suggesstion or comments?

As I know You can do that ,
in VS2005 you can even declare a variable with name in other languages like Farsi or Arabic not just the value! and it works fine.

<br />
<br />
//Auto Generated code with Resources<br />
<br />
        /// <summary><br />
        ///   Looks up a localized string similar to سلام به مردمان نیک کد پروژه.<br />
        /// </summary><br />
        internal static string متغیرسلام {<br />
            get {<br />
                return ResourceManager.GetString("متغیرسلام", resourceCulture);<br />
            }<br />
<br />
<br />
<br />
        private void button4_Click(object sender, EventArgs e)<br />
        {<br />
            MessageBox.Show(Properties.Resources.متغیرسلام );<br />
        }<br />
<br />

just as a tip the persian phrase means "Greetings Good People at CodeProject"

WinForm supports resources (and the support is better integrated in VS than what you find for ASP.NET - basically it's good enough for hobby translated programs). If you translate professionelly do NOT use VS to manage the translations, let the professionel translation tools do what they do best.

As a basic rule, the user has already selected the language (the language of the Windows userinterface), so while it might appear a great idea to allow the user to select language, there really is no need. As it's not that easily done either, I would not bother if I was you.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
