Pasting image to word: image size issues

_iobuf5-Aug-09 9:43

5-Aug-09 9:43

I have a word document and I want to paste an image into a cell. Both the cell and the image can be of any size. I am using Microsoft.Office.Interop.Word to do this. After getting the right cell and copying the image to the clipboard, when I call cell.Range.Paste(); the image gets pasted into the document, but it doesn't get auto resized to fit the cell dimensions. If I select the image with my mouse and then press ctrl + v, the image is re-pasted and auto resized.

Is there a way to paste the image from code and have it resize?

Thx

one more c# xml issue

hello once again today -
I do have one more question and I hope that someone can help me one more time today again. I have an xml document similar to this one:

<xml>
<person id="1">
<first>John</first>
<last>Smith</last>
</person>
<person id="2">
<first>Mark</first>
<last>Smith</last>
</person>
</xml>

I want to get partial xml data, for example I want to get just the second person data, and I want to get based on the attribute, in this case the ID. Is there a way how to do that? Thanks in advance, Laziale

Yes; look into XPath queries. The correct query would be something along the lines of "//xml/person[id='2']". You simply have to plug that into and example like this; there are other examples you could use as well

You can use an XPath expression to retrieve the xml fragment, ./person[@id='2'] will return the second person element in this case

You should look into LINQ for this, I absolutely LOVE LINQ when working with XML files.
http://www.codeproject.com/KB/linq/LinQ_To_Xml.aspx

That's a good article that shows pretty much exactly how to do what you need.

Sorry for the crappy link, all the fancy JavaScript that formats it doesn't work on my iPhone (stupid safari)

Virtual method in sealed class

Hello ,

Virtual keyword allows us to override that method in child class.

Now when we declare a class as sealed class then we cant inherit . In That case why it allows us to decalre virtual keyword in static class when any other class inherit it ?

Pls expaln in deatils

Jaddu

It will not allow you to declare a virtual method in a sealed class. You can't have instance members in a static class as well.

You can't. Have you tried it?
In a static class, if you try to create a virtual method the compiler will spit at you with
A static member cannot be marked as override, virtual, or abstract
In a sealed class
... is a new virtual member in sealed class ...

Regex issue

Hey guys,
Can anyone help me in writing the simple regex. Here is the situation:

I have a text file something like:

// Contents
// Contents
MyDataBlock
{
   @$
      The datablock text
   @$
}
// Contents
// Contents

I want to extract "The datablock text". There is single "MyDataBlock" in this text file. It means that i have to extract entire MyDataBlock {...} and then what is inside @$ into a regex group.

I've created a regex. It is successfully extracting following in regex group <b>DataBlockContents</b>:

   @$
      The datablock text
   @$

But i don't want @$ in the regex group DataBlockContents. How can i do so ? The regex i created is:

MyDataBlock[\\w\\s]*{(?<DataBlockContents>[^}]*)}

Imtiaz

The same way you don't get the { and } in the group?

Do you have control over how the file is formatted? Why use @$ instead of something else?

At runtime find the application's build version?

Is it possible to pull from somewhere after the application has been compiled to know what it's build version number is so I can show it in a label? I am thinking I can pull if from the assembly but my attempts have failed. Please can someone point me in the right direction?

Here is what I am currently doing and it does not match the build version of the application that I am compiling.

lblAppVersion.Text = "Version: " + System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString() + " or " + System.Reflection.Assembly.GetCallingAssembly().GetName().Version.ToString();

What do you want the text in the label to look like?

To Get This "Ver. 5.1.2 Rev. 3"

Try like this;

Dim avi As System.Version = System.Reflection.Assembly.GetExecutingAssembly.GetName.Version
lblVersion.Text = "Ver. " & Format(avi.Major, "###0").TrimEnd & "." _
& Format(avi.Minor, "###0").TrimEnd & "." & Format(avi.Build, "###0").TrimEnd _
& " Rev. " & Format(avi.Revision, "###0")

Of course this is not the publish version (just saw last post)

it is very easy tog et this info
This is a code for this

//get the version from the assemblyinfo.cs
// Version information for an assembly consists of the following four values:
            //
            //      Major Version
            //      Minor Version 
            //      Build Number
            //      Revision
            //
            Version v = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version;
           //add to label
 lblVersion.Text = v.ToString();

This information is stored in the AssemblyInfo.cs under Node 'Properties' in Solution explorer!

Happy Coding!

Thanks I learned that c# does not auto increment the version per each build. That was the issue I was having.

Change Headers in DataGridView [modified]

I am having a problem changing the forecolor of a DataGridView header. I have tried the following code:

dgvMaintenance.EnableHeadersVisualStyles = false;
DataGridViewCellStyle dgvcs = dgvMaintenance.ColumnHeadersDefaultCellStyle;
dgvcs.BackColor = System.Drawing.Color.DarkGray;
dgvcs.ForeColor = System.Drawing.Color.White;

The backcolor changes, but the forecolor does not.

I have also tried:

dgvMaintenance.EnableHeadersVisualStyles = false;
DataGridViewCellStyle dgvcs = new DataGridViewCellStyle();
dgvcs.BackColor = System.Drawing.Color.DarkGray;
dgvcs.ForeColor = System.Drawing.Color.White;
dgvMaintenance.ColumnHeadersDefaultCellStyle = dgvcs;

with the same results. I have also added code to change the font and that works too.

What am I doing incorrectly? Thank you for any help.

You could use a regular expression.

There's a bunch of regular expression classes in .net (Start here[^]

If you don't know about regular expressions, you might want to read up a bit on them. There's a site here[^] that's worth looking at.

It's also worth having a tool to test them with before you start coding them. A popular one is Expresso[^].
