There is far too much code posted here and it is not properly formatted to be readable. Please read How-to-get-an-answer-to-your-question[^], then go back and edit your question to format your code properly and also remove all the sections not relevant to your question.

I seriously doubt that anyone has got the time to wade through all of that code. Might I suggest that you cut it down to only display the important parts. Anyone that is curious enough may ask for more. In any case your question is not clear: try to rephrase it.

Hi,

welcome to CodeProject. We are here to help you. However we also insist on you making that no harder than necessary, so you'd better read the forum guidelines first. There is a nice "how to ask a question" or "how to get an answer" message.

It will tell you many things, such as choosing an informative subject line, including only relevant parts of code, and using PRE tags when doing so.

I did not read all of your code, it is simply too hard. I did notice:

1.
you have a couple of Encoding.ASCII in there, that is one way of turning foreign characters into question marks.

2.
you seem to have a GC class, that isn't the best choice of names, as .NET already has a GC class. There probably isn't a real problem here, it is however a bit confusing.

Hope this helps.

Combobox problem

Hi all,
I am using combobox Selected Change committed event,
and want the text selected by selected by user.

But problem is it only gives me text which was previously selected.
Suppose there are items as A, B, C, D

Now if user selects A on cmbTables_SelectionChangeCommitted event

its giving blank,

if again user selects A then its giving A.

Its giving the value which was previously selected.

private void cmbTables_SelectionChangeCommitted(object sender, EventArgs e)
       {
           System.Diagnostics.Debug.WriteLine(cmbTables.Text);

       }

Why this?
Is there way to overcome this?

Also if some items are present, it show blank, user have to select 1st item from dropdown.
I know we can set that thru coding, but why can't it set by default to 1st item.

regards,

I've never used the SelectionChangeCommitted event; did you notice it is part of Microsoft.VisualBasic.Compatibility.VB6 which suggests me to avoid it, it probably exists to mimic some quirks from VB6. I have used SelectedIndexChanged successfully, however I also code carefully with all such XYZChanged events, as some of them will fire more than once (changing a selection may be an unselect followed by a select), and Changed sometimes is and sometimes isn't to be taken literally, i.e. they may also fire when the same selection is made again.

How did you notice this?

If I look into the object browser i just see:

Public Event SelectionChangeCommitted(ByVal sender As Object, ByVal e As System.EventArgs)
Member of System.Windows.Forms.ComboBox

But in the Microsoft.VisualBasic.Compatibility.VB6 namespace there is :

Public Event SelectionChangeCommitted(ByVal sender As Object, ByVal e As System.EventArgs)
Member of Microsoft.VisualBasic.Compatibility.VB6.ComboBoxArray

I'll let you in on a little secret: I occasionally read the documentation; Google the keyword (class name or more) to locate the relevant MSDN page, and pay attention to one of the first lines, which names the namespace. If it contains VisualBasic or VB6, I always suspect it is there for compatibility, probably to copy historic quirks.

Intellisense is great for saving you from some typing, and for suggesting member names, it is not a replacement for the documentation though. When I start using a new class, I read the class page and the list of members; and for each new class member I use, I would read the specific page, especially looking at the remarks, and the list of exceptions, as they often contain hints on less-than-obvious behavior that is to be expected.

In this particular case, I may have been too hasty though, seems like SelectionChangeCommitted also is a normal event in System.Windows.Forms.ComboBox, so I must have read the wrong page. However, I stand by my comments on XyzChanged events in general.

When i use SelectedText, its give previously name.
But if i use SelectedIndex, its giving currently selected item.

I am trying to achieve. There is a DataGridView. I am filling DataSet with approx 20 tables. Then adding these Datatable names to combobox.

Now when user selects a Datatable from comboxbox, lsetting dataMember property of DataGridView to Table Name.

Ques -> Is this Approach correct?
Here i also have to declare DataSet at class level (which i think remain in memory until class/application alive).

void SomeMethod()
{
      dsTemp = new DataSet();
      dsTemp.ReadXml(ofdXmlFile.FileName);
      dgvDS.DataSource = dsTemp;

      for (int i = 0; i < dsTemp.Tables.Count; i++)
      {
           txtContent.Text += dsTemp.Tables[i].TableName + "\r\n";
           cmbTables.Items.Add(dsTemp.Tables[i].TableName);
      }
}

DataSet dsTemp = null;
        
private void cmbTables_SelectedIndexChanged(object sender, EventArgs e)        
{
      dgvDS.Columns.Clear();
      dgvDS.DataMember = dsTemp.Tables[cmbTables.SelectedIndex].TableName;
}

Now above working correctly.

But when i use this below one its not working as expected
But here i dont have to declare DataSet at class level(and it also got garbage collected once SomeMethod Exit).

void SomeMethod()
{
       DataSet dsTemp = new DataSet();
       dsTemp.ReadXml(ofdXmlFile.FileName);
       dgvDS.DataSource = dsTemp;

       for (int i = 0; i < dsTemp.Tables.Count; i++)
       {
            txtContent.Text += dsTemp.Tables[i].TableName + "\r\n";
            cmbTables.Items.Add(dsTemp.Tables[i].TableName);
       }
}
        
private void cmbTables_SelectedIndexChanged(object sender, EventArgs e)
{
       dgvDS.Columns.Clear();
       dgvDS.DataMember = cmbTables.SelectedText;
}

Also one more quest, when i try to iterate dataset thru foreach loop like

foreach (DataTable dt in dsTemp)
{     txtContent.Text += dt.TableName + "\r\n";
      cmbTables.Items.Add(dsTemp.Tables[i].TableName);
}

it gives error why?

Error 1 foreach statement cannot operate on variables of type 'System.Data.DataSet' because 'System.Data.DataSet' does not contain a public definition for 'GetEnumerator'

How to overcome this? if i want to use foreach only?

1.
The hint is in the documentation:
"SelectedText gets or sets the text that is selected in the editable portion of a ComboBox".

A ComboBox allows you to choose one item from a list; doing so will fire some events and set some properties, in particular SelectedIndex and SelectedValue. These apply to you point-and-clicking in the list.

It also often allows you to type a text yourself; if so, you can edit the text, select part of it, copy, cut, paste, etc. There SelectedText works like it does in a TextBox. That is unrelated to point-and-clicking in the list.

When you do point and click, the TextBox part will reflect what you have selected, and under some conditions, it will also select it (turning it white on blue), at that time SelectedText would become equal to SelectedValue.

Hence: use SelectedIndex for retrieving the index inside a SelectedIndexChanged handler.

2.

foreach (DataTable dt in dsTemp)

does not work when dsTemp is a DataSet. A DataSet holds tables but does not enumerate them automatically.
However

foreach (DataTable dt in dsTemp.Tables)

should work for you.

Thanks for your reply and time.

also could you give some light on DataSet object i declared. Given the 2 approaches i used, Is my concern is correct i.e

a) By declaring DataSet at form level(outside method). Is this going to remain alive until form object is alive?

Am i correct here?

regards

if your DataSet were a class member of your form, it would stay alive as long as a reference to it exists, which probably would coincide with the life of the form. You should be aware that DataSet has a Dispose() method which you should call when you no longer need the DataSet, so either apply a using construct (that is only suitable for local memory, inside a single method) or make sure to stuff it in a FormClosing handler.

Disconnect SSL connection after user has logout

Dear All,

I need a little help here.
Currently I have a website which is not under secure (E.g non-SSL pages).
If the user clicks login, the system will verify whether the login page is a secure page. If it is not, it will had a change of the URL to "https://" instead of "http://" which brings the website to be under secure.

However, if the user logout, my website will disconnect the SSL connection.

Now my problem is, how to disconnect the SSL connection in C#?
I tried searching googles, forums, etc for about a week and most of the replies are by using "FormsAuthtication.SignOut()" but it does not work in my website.

I include "FormsAuthtication.SignOut()" and redirect to "http://" page, it give me an error:

"The page must be viewed over a secure channel
The page you are trying to view requires the use of "https" in the address.

HTTP 403.4 - Forbidden: SSL required
Internet Information Services"

Please give me advie on this.
Many thanks.

How do I find the BITMAPINFOHEADER of a image

Hi
Im using AVIStreamWrite to create a video using a string of JPG's from a ethernet camera. I believe that I have to use aviSetFormat before I can use the above function. One of the arguments for the aviSetFormat function is a BITMAPINFOHEADER. I have tried settings it up manually but the video is just black. So is there a way of finding the BITMAPINFOHEADER of a image using a function call?

Thanks
