Hi,
I have a panel on a windows form.
In the panel, I have a label, I have set the visible property of the label as False in design time.
now at runtime, in a function I am trying to make label visible like this,
label1.visible = true;
but the label1.visible property does not change, it still has false value, but once the form executes completely, label becomes visible, I cannot understand, How this is happening.
can someone tell me that why the label1.visible property does not become true, when I explicitly assign true to it.
Thanks in advance,
Regards
Mahesh

It sounds like you are running a process that is holding up the UI, basically the form is not being refreshed until the process is complete. Adding the following line after settings the visible property of the label to true should work..
label1.Visible = true;
form1.Refresh();
Life goes very fast. Tomorrow, today is already yesterday.

What do you mean by this?
If you are calling a function which takes a long time to exexute and you are changing the property inside that than it will only appear after the task.
You may look at Backgroundworker to prevent this.

Welcome to the wonderfull world of visible!!
This is a really good example of stupidness within the framework. The setter flags that you <want the="" control="" <i="">to be visible. The getter reports if the control is visible. The two are not the same, you can also see the same behaviour with enabled.

So the situation is the folowing
Inside a tabview control; i add programaticly a number of tabs (the number is not fixed); on each tab i add a listview. My question is how do i add an event item so that when i click any item from any list i fill a textbox with something from that item; my code looks like this
public void lv_SelectedIndexChanged(object sender, EventArgs e)
{
while (n!=0)
{TabPage tp=new TabPage();
tabControl1.TabPages.Add(tp);
ListView lv = new ListView();
tabControl1.TabPages[k].Controls.Add(lv);
n--;
}
}
I've written just a portion of the code.Help will be apreciated.Thank you in advance.
Alex.

Immediately after creating the new listview instance, subscribe to the desired event.

Hi,
not exactly sure what you want. Here are three pointers:
1.
you can program anything by code that you also could do interactively in Visual Designer; all VD does is add code in some file (myForm.designer.cs), there is no magic involved; look at such code, and do the same thing in the appropriate method yourself.
2.
you can share event handlers across multiple controls; all event handlers have a first argument object sender that serves to identify the exact sender of the event; you would probably have to cast it to the appropriate control type first.
3.
you may find it useful to somehow make one Control (say ListView) refer to another Control (say TabPage); every Control has a object Tag property that serves no particular purpose, so you can store anything you like there, and use it where useful. As an alternative you could create a map using a Dictionary.

It's purpose has always been to provide User-defined data associated with the object. I think it should be programmer-defined, but hey ho.

That's what I meant to say, unlike the other properties Windows doesn't use it, so the programmer can store just anything in there.

What i want to do is the folowing|:

Read the previous answers, it's mostly there for you.
0. Listen for the event.
1. Identify which list raised it.
2. Read the value.
3. Wash, rinse and repeat.

I am trying to log a user into a site using HttpWebRequest or WebClient Class
Now the site will probably issue me some cookies that tell the browser i'm already logged in. I need to pass those cookies on subsequent requests so I can fetch the data on that page.
Thanks in advance

|

Exactly. As for the cookies, just copy all the cookies you receive in the Response to the subsequent Request(s). This is simple.

Hi,
I've a list box with 4 columns out of which one column has width as 0 and want to restrict the users to re size it and see the content. How can get this ?
Thanks

If you don't want the content vsible, why put it in the visible part of the control at all? I would either:
0. Store the required non visible data in the Tag property of the ListViewItem
1. Subclass ListviewItem to have a new property of the correct type to store the data to avoid unboxing/boxing associated with 0.

I thought, oh here we go that's s stupid question. Then I read the details and remembered that I have the same problem, not one I worry about but it is there.
I use a DGV if I need to hide a column, it support visible. I also have a utility that loads any table/dataview into a listview that assumes the first field is the ID and it gets loaded into the tag property.
If the list is short I sometimes load the datarow into the tag property and only create cols for the fields I want to display.

Have some issues and questions about creating a .dll from code in the form of a string array and a file. I seem to be close, but errors are raised when the code tries to creat the .dll.
Main question is, does the 'OutputAssembly' refer to the file name to create? Whenever I run the code below it says it could not find the file that 'cp.OutputAssembly' is set to. Also if this line is commented out, it says it could not find a randomly named file in a temporary directory.
The other question I have is if there is any difference between creating the .dll from an existing file or a string array. I plan on having the system create a common .dll for both the main program and for other .dll's the main program creates. These non-common .dll's can then be used directly in other programs.
This code is to create the common .dll .
public CompilerResults CompileImageAquisition(string OutputFile)
{
CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
CompilerParameters cp = new CompilerParameters();
CodeTypeReferenceCollection cref = new CodeTypeReferenceCollection();
cp.OutputAssembly = OutputFile;
cp.GenerateInMemory = false;
cp.TreatWarningsAsErrors = false;
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\PresentationCore.dll");
cp.ReferencedAssemblies.Add("System.Drawing.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.Windows.Forms.dll");
cp.ReferencedAssemblies.Add("C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\System.XML.dll");
CompilerResults cr = provider.CompileAssemblyFromFile(cp, ImageCoderSourceLocation);
if (cr.Errors.Count > 0)
{
Console.WriteLine("Errors building {0} into {1}", ImageCoderSourceLocation, cr.PathToAssembly);
foreach (CompilerError ce in cr.Errors)
{
Console.WriteLine(" {0}", ce.ToString());
Console.WriteLine();
}
}
else
{
Console.WriteLine("Source {0} built into {1} successfully.", ImageCoderSourceLocation, cr.PathToAssembly);
}
return cr;
}
