Do you mean a form ?

There is nothing built in to do this, but you can write code to find out the size of the main screen, position it where you want, and handle the event when the form is moved, and move it back.

DataGridViews and ComboBoxes

Illegal Operation24-Jun-09 14:02

Illegal Operation

24-Jun-09 14:02

I have a WinForm with a DropDownList and DataGridView. I need to display the States based on the Country selected.

This is my Code:

private void cbCountry_SelectedIndexChanged(object sender, EventArgs e)
{
    if (loading == false)
    {
        CountryId = (int.Parse(cbCountry.SelectedValue.ToString()));

        this.dsWBGT = dataComm.GetStateByCountryId(CountryId);
        dgvState.DataSource = this.dsWBGT;
    }
}

When I step through the app everything works and the dataset gets the correct info but the DataGridView only display (Collection)

Can someone tell me what am I doing wrong?

I am populating the combobox with the following code:

private void PopulateCountries()
{
    DataSet dsCountries = dataComm.GetCountries();

    cbCountry.DataSource = dsCountries.Tables["Country"].DefaultView;
    cbCountry.DisplayMember = "Country";
    cbCountry.ValueMember = "Id";
}

Getting XHTML tags by tag name

24-Jun-09 12:00

In JavaScript you can run document.getElementsByTagName ("img") to get all of the image tags. Can you do something similar in C#?

Also you can do this is JavaScript:

var image = document.createElement ("img");
image.getAttribute ("src");

Again can you do something similar in C#? And if so, how?

This is how I'm getting the webpage: http://www.tech-recipes.com/rx/1954/get_web_page_contents_in_code_with_csharp/[^]

If it's really XHTML and not just plain old HTML, you could just treat it as xml: use XmlDocument and its SelectNodes(string xpath) function
At least, that's what I would do..

The xpath would be something like "//img/@src" I think (if you want all src attributes of all img's as your code seems to do)

Okay I'll give that a try.

I've found out that the XHTML isn't completely valid. Some of the tags aren't closed properly. Here's in excerpt:

<META HTTP-EQUIV="content-type" CONTENT="text/html; charset=UTF-8">
<meta name="robots" content="noarchive"/>
<meta name="description" content="/a/ is 4chan's imageboard dedicated to the discussion of Japanese anime and manga."/>
<meta name="keywords" content="imageboard,japan,anime,manga"/><link rel="alternate stylesheet" type="text/css" href="http://zip.4chan.org/yotsuba.9.css" title="Yotsuba"><link rel="stylesheet" type="text/css" href="http://zip.4chan.org/yotsublue.9.css" title="Yotsuba B"><link rel="alternate stylesheet" type="text/css" href="http://zip.4chan.org/futaba.9.css" title="Futaba"><link rel="alternate stylesheet" type="text/css" href="http://zip.4chan.org/burichan.9.css" title="Burichan"><link rel="alternate" title="RSS feed" href="/a/index.rss" type="application/rss+xml" /><title>/a/ - Animu &amp; Mango</title>

While some of the tags are somewhat formed properly, some aren't. The first one is easy:

result.Replace ("\"/>", "\" />");

I think I could use regex for the tags missing a closing "/" but I don't know how to do that.

[Edit]

Okay the result.Replace bit isn't working.

I'm afraid you may have to use a custom parser, for HTML.. That will work, but it's a lot of work to make.

Jordanwb25-Jun-09 7:29

25-Jun-09 7:29

Well all of the HTML seems to be properly nested as per the XHTML specs, but some of the tags simply aren't closed properly. All I may need to do is C#'s version of PHP's preg_replace function.

menustirp items disappear from designer, but still in properties list

I have a MDI project. The child forms have a menustrip, the menustrip used to have items like File, Edit etc. But today when I opened the project the items where gone from designer view. I can still find the items in the dropbox that contain all objects on the form, but when I select them they do not appear. It is not the allow merge property the most people think it is, this is in design mode not run time. The menu doesn't even appear at run time. I have tried google and other sources no sucesss?

Anyone know what causes this ???

Its look like the problem is in Visual studio IDE

you might want to try this (Work around)
remove the strip from form try adding it again on the from
this might solve your problem

This is what I have found out so far: it seems that what you are working with the forms resource folder, and you delete a resource file, I get a message saying that the designer might become unstable. as soon as I delete a resource and I get the warning message and I say Ok, then the menu items disappear and some other random items disappear. The solution to avoid this problem is instead of deleting, one should exclude instead.
