Hi i had a problem this intialization control on form.
Suppose i had an ActiveX control on my dialog.And i had an
RadioButton(with Checked = TRUE)onto dialog also.For this button i had ChackedChange event handler, which commit an action with those ActiveX control.But when form initialized this event arised, but object still not created, and cause of i get access violation!!!
Rather, the control created on this row:
MyObjAx = new MyObjAx();(or may be properly say begin created???)Into InittializeComponent method,after this routine arised event for my RadioButton handler,but there is i see that this component still not created.One had right pointer,but in debug window i can see that fields of one not initialized.
How i can avoid this stumble???
THANK.

hi,
The reason is because you are trying to access your activexcontrol before initializing the control.
You can do one thing. Just remove your radiobutton's ChackedChange event handler declaration and add it after creating the ActiveXcontrol.

hi
I suppose activeXcontrol initialized in string
Me.MyObjAx = new MyObjAx();
And this routine invoke before ChackedChange event handler.
Is it so???

hi,
You wrote some code on changeevent handler to do something with your activeXobject. right. But you are trying to use that handler before initalising that object. Add changeevent hadler after creating object of your acticeXobject.Ok.
Did you got what i am trying to explain ?

Hello all.
I'm having a problem letting one form inherit another. I have a simple wizard implementing the base functionality and then I have a couple of wizards that inherit from the base wizard, where I add the necessary textboxes, comboboxes and so on. I saw it called "Visual inheritance" at one place...
At first it worked relatively well but now it is all a mess. My problem is this: if I add for example a textbox to an inherited form in the designer and I change a couple of properties on the textbox (AllowReturn set MultiLine to true, set some default text e.t.c.), I save the form (usually goes well) and then I compile and suddenly the textbox looses all the properties I have set -except for the ID, and moves up to the upper left corner of the form!?! Or I don't compile but I add an eventhandler for some other control, goes into the code and then returns to the designer and KABOOM! The textbox is in the upper left corner without the properties I gave it!
What have I missed? I had minor problems before, that the controls occasionally lost the properties overriding the basewizard properties, but not like this. I don't know if it is related but it seems that since I moved to WinXP servicepack 2 about a week ago, it has stopped working alltogether.
Any ideas? Getting a bit desperate as my project is due soon!
Thanks

hi,
This may not the reason but still you can check the Modifiers property of the object's that you are trying to access. Change it to public. Cause you are changing the values after inheriting the object.
Change the property Modifiers and set value true.

Thanks!
That may very well be a solution to some of my problems; I'll try that.
I restarted my computer and that helped on the most frustrating thing (the textbox now keeps it's size even after saving and compiling the project), so maybe I just really need to reinstall my computer, but hopefully your tip can solve the other properties being lost (which I have had since I started with the inherited forms).
Thanks

Hi,
I created a scheduler for make some tasks every days.
I used a treeview.
SCHEDULER
|->MONDAY|-> TASK1 : HH:MM:SS
| |-> TASK2 : HH:MM:SS
|->TUESDAY ...
...
Now I can used this interface if I have only the start TIME.
But today, I would like to used START TIME and STOP TIME and in this view the interface is very complex.
I looking for an interface that I can select like calendar in outlook with my mouse or keyboard to determinate the start and stop time.
Best regards
youssef

Use a datagrid to display all the schedule details.

hi,
You wrote : Now I need to access the whole page contents from to.
Now you are accessing the text content. What you need to do is the individual objects which is avilable in the web form. Am i right.
if so, use this code block to access the controls.
foreach(controls ctl in Page.Controls)
{
}

Take a look at the MSDN.
At bottom of the overview page for a type you find the Requirements section which specifies its namespace as well as the assembly providing the type.

hi,
I am getting Invalid File Format Exception in following snipet, please point out the mistake.
-------------------------------------
string _report = CreateReport(); // returns rich text formated report
ms = new MemoryStream(Encoding.Unicode.GetBytes(_report));
richTextBoxEx.LoadFile(ms, RichTextBoxStreamType.RichText); // Exception
-------------------------------------
regards

infact it is.
if i save the string using folowing
-----------------------------------
FileStream MyStream = new FileStream(saveFileDialog1.FileName, FileMode.Create);
StreamWriter MyWriter = new System.IO.StreamWriter(MyStream,System.Text.Encoding.Default);
string _report = CreateReport();
//writing the report
MyWriter.Write(_report);
-------------------------------
i get the rtf file.
i don't know whats going wrong.
what i am intending to do is, instead of saving the file on some location and then loading it in the RichTextBox, give the Stream (that is prepared from "_report" string) directly to the RixhTextBox.
please give some inputs
regards

hi,
Use a StringReader object to save the content of a RichText.
StringReader StrReader;
string Content=RichText.Text;
StrReader = new StringReader(Content);
And then continue.
