I have this functionality i want to port from WinForms but i run into a few problems and i can't continue. What it does is move a panel(canvas) around as i click and hold and drag the mouse). I saw the sample using TranlateTransform(XAML) but i can't get any code-behind example, this is dynamic and interactive. I managed to make some out only need the translation solved(and possibly a good approach on using this with Margin, wich seems the only tool i got to moving the canvas around?).
Code Block#region Pan tool
private bool mMovingPanel;
private Point mMousePos;
private void panel1_MouseDown(object sender, MouseEventArgs e)
{
mMovingPanel = e.Button == MouseButtons.Left;
// prev mouse pos
mMousePos = panel1.PointToScreen(e.Location);
}
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
if (mMovingPanel)
{
// "this mouse pos"
Point pos = panel1.PointToScreen(e.Location);
// "this mouse pos" - "prev mouse pos" = offset
Size adj = new Size(pos.X - mMousePos.X, pos.Y - mMousePos.Y);
// Location + offset = Location (final - unassigned)
Point loc = panel1.Location + adj;
if (panel1.Width >= this.ClientSize.Width && panel1.Height >= this.ClientSize.Height)
{
if (loc.X > 0) loc.X = 0;
if (loc.X + panel1.Width < this.ClientSize.Width) loc.X = this.ClientSize.Width - panel1.Width;
if (loc.Y > 0) loc.Y = 0;
if (loc.Y + panel1.Height < this.ClientSize.Height) loc.Y = this.ClientSize.Height - panel1.Height;

// Location(final - assigned)

mMousePos = pos;
}
}

This is my attempt, i know it lacks but hopefully it will speed things up:
Code Block#region Pan tool

Vector adj = new Vector(pos.X - mMousePos.X, pos.Y - mMousePos.Y);
// Location + offset = Location (final - unassigned)
Thickness currentThickness = new Thickness();

I like C# but its useless in my applications because I can not protect my source code as its always included in deliverables.
Is there any real solution coming for this in near future or should I just give up C# .NET.
I believe this should be major concern for many but I haven's see Microsoft taking any role for this.

No.. You don't need to give your sourcecode to your client.. After making the setup file, there won't be any sourcecode in your setup file..

I tried this by making simple windows forms application and publish it. I select The application is available offline as well.
It generated setup.exe and subdirectory Application files. Under that there is file application.exe.deploy
I renamed that to be application.exe and open it Lutz Roeder's reflector. It was able to re-generate my source code from that. I think my clients can do same.

No. The generated code won't be the same as the original code that you wrote..

Atleast all of my business logic is there in very clear form.
I don't really feel confident. Reverse-engineering or hacking is other thing as this is way too easy to steal the hard work.

You would need to look at using an obfuscator[^] to make it more difficult to reverse-engineer the source code for your application.

Hello friends i want to know
how do i set source of the datagrid at runtime
if possible can u send me the code of it.
|
|
|
|
|
Let's say "DataGrid1" is the name of your DataGrid. "ds" is the name of DataSet that you have filled your data.. so, you can put this code below in your Page_Load()
<br />
DataGrid1.DataSource = ds.Table[0];<br />
DataGrid1.DataBound();

Hello,
I have created a C# project with two different languages (english and Spanish), and I would like to determine, OUTSIDE of the project that uses the language DLLs, what type of language the DLL contains.
In C++ you could set the language of the DLL and right click on it and see for instance: "Spanish (Mexico)"
[[ From explorer right click on DLL and select properties,
click on the Version tab, in the 'other version information'
click on Language ]]
In C#, my language DLLs all have "Language Neutral"
[[same thing right click ...]]
Which leads me to the following questions:
1. Is it possible to set the "language" property of a C# resource DLL?
2. Can I get the language "property" of a C# resource DLL programatically?
Thanks
|
|
|
|
|
I think this is defined in Project -> Properties -> Application tab
there you have an 'Assembly Information' button next to "Output Type", and there is a place where you select neutral language.
Now, I have no idea what that actually does change, but that would be the info you'd see when you check the properties of the DLL I assume.
regards
|
|
|
|
|
Thanks - not quite...
That just sets the "default" language for the application:
[assembly: NeutralResourcesLanguageAttribute("en-US")]
What I am looking for is the same thing for resource DLLs, but I don't think it exists...
Right click on a C++ DLL, select properties, select Version tab, click on Language in the 'other version information' group box

Hello, and thanks for taking the time to read me...
I am starting with Visual C# to build a Windows application, although I have long experience with Web design in PHP, Javascript, XML/XSL...
I am trying to build a program that would use data from an XML Database file, locally, with online updates.
The program needs to be able to run offline, but check for updates on the XML file when online.
So I have several questions:
- First, I'd like to understand how program updates work: Is there a standard protocol in Visual C# that looks for application updates? Or do I need to program that?
If so, I assume it looks for update of the .EXE, or how would it handle external files?
- So then, I was thinking it may be easier to embed the 'local' XML into the program, and hide it from the user, but I don't see an easy way to use my XML directly. It seems like no matter what I do, I should 'load' the XML into a dataset, which to me sounds absurd since Visual C# is supposed to handle XML in native. After all XML is a structured object, so why can't I access it directly? (or if I can, please tell me how!!!)
The idea behind using XML is that most of my data is formatted text that I later need to output in the form of Word or PDF documents, so it seems obvious to store the data in XML and use XSL:FO transforms on the data to output in the format I want in the end.
I also find a little odd that Visual C# would only handle formatted text as RTF, and not HTML or XML with XSL, but RTF is easy enough to transform in XML, so I'll deal with that... unless someone knows of controls designed to handle HTML/XML editing easily (and that won't cost me a fortune!)
Any insight would be very welcome!
Thanks!

You may want to look at the ClickOnce API for updating your app. http://msdn2.microsoft.com/en-us/library/t71a733d(VS.80).aspx[^]
You can retrieve the XML and load it into an XmlDocument. Then you can access it using XPath expressions, or iterator over nodes, or however you need to.
only two letters away from being an asset

Thanks for the tip on ClickOnce.. .that seems ot be what I need to look into.
Now, I see I can load my files into an XmlDocument, and then do whatever with it. Is there a way to actually embed an XML file onto the program?
It seems like I can load a new 'Item' to my project... but then what how do I access it? Do I still have to 'link' or 'load' it as a xml.document?
I have to admit I am a little lost with all the different 'items'

Hello,
Simple problem but its causing me grief.
I want to consume an RSS feed and display a varying amount of stories on different web pages.
If I retrieve the xml document and then use xpath to drill down to the items I get a nodelist like so:
XmlNodeList nl = rssDoc.SelectNodes("rss/channel/item");
Now, what is the best way (if this list contains say 30 stories) to convert it to a node list of say 3 stories?
I appreciate this is probably either:
a. 2 lines of code
b. not possible.
Help please?
|
|
|
|
|
I'm not sure to understand the problem here, and I may not be alone...
You have the nodelist. You want to crop it out to get 3 out of the 30? Is that it?
What's your criteria for selection? It seems to me you can sort in many ways, and then pick the first 3. Select nodes out of the list with XPath, or an XSL transform, since RSS is all XML.
Maybe I'm missing your question here... but in any case, there is nothing logical that's impossible to code!
|
|
|
|
|
>> You want to crop it out to get 3 out of the 30? Is that it?
Thats exactly it.
Basically some pages will display 25 stories some 2 etc.
>> but in any case, there is nothing logical that's impossible to code!
Agreed ;o)
|
|
|
|
|
In case anybody else is looking for the solution to this:
xDoc.SelectNodes("rss/channel/item[position()<8]");

Will this[^] article help?

Hi All,
I have a TreeView for which I have created images. Rather than using a single image per item, I've created an array. So rather than than a 16x16 BMP, I am using an array of 16x16 BMP's. The array includes standard and selected images. They are laid out as [standard, selected] pairs.
I add the image to the the tree view. However, when dispalyed, there are no images. I beieve this is because the control is not performing the derefernce into the array. How do I get the TreeView to properly use the array of images? TreeView uses and ImageList, and the array is a list (I think...).
Jeff
public static ImageList images = new ImageList();
...
images.Images.Add(new Bitmap("TreeViewImages.bmp"));
TreeView.ImageList = images;
...
TreeNode node = new TreeNode();
...
int ImageIndex = GetImageIndex(GetTagNumber());
node.ImageIndex = ImageIndex;
node.SelectedImageIndex = ImageIndex + 1;
private static int GetImageIndex(int number)
{
return ...;
}
