Hi,
I have an app developed using Windows Forms. I need to save the size that the user resizes the app to, so as to open the app window to that size when the user restarts the app. I also need to save the desktop location of the app, so as to display the app window at that location when the app restarts.
What is the best way to do this?
I have implemented this using a config file, such that I save the size.width, size.height, and location.x, location.y of the app when the event to close the app is fired. The problem with this is that when the user closes the app in its minimized state, then the app size is 160 x 30, and the app re-opens at this size at the next restart. 
Thanks.

Check first before writing to the config file ,if
if(this.WindowsState==FormWindowsState.Normal)<br />
{<br />

Hey guys, has anyone else run accross this behavior before?
When using dataadapter.update within the context of a transaction, if the transaction succeeds your datasource has .acceptchanges called and everything is fine. If that transaction fails however, .acceptchanges is still called.  
this just doesn't seem right to me? according to a post i found on google ms's recommended way of dealing with this is to make a copy of the data before submitting the update, then if the transaction fails, clear the data and merge the previous version back into the main dataset. i was baffled when i came upon this the other day.
does anyone have any insight as to whether this behavior might be changing in the next release of the bcl? i don't have any of the beta's to check it out and i'm more just curious than anything. seems like if the transaction failed they should just leave the rowstate data as is...

I'm having troubles with the MonthCalendar control.
I want its culture to be en-US, but is always
shows the names according to the current locale settings.
My locale settings are Bulgarian and the control appears
twice as wide and it's ugly. It displays the whole names
of the days of the week, not just the first three letters
and it's very very wide. I tried changing the culture of the
assembly but it appears that:
Error emitting 'System.Reflection.AssemblyCultureAttribute' attribute -- 'Executables cannot be localized, Culture should always be empty'
Is there a way to get MonthCalendar always display the
english names?

Hi,
I use an ArrayList to store class objects which have some public properties defined.
After adding objects to the ArrayList and binding the ArrayList to a datagrid I see all entries of the ArrayList and all public property fields of the class.
However, if I add further objects to the ArrayList or remove some, the datagrid is not updated at all. I have to reset the DataSource property and make a new databinding to see the current ArrayList content
e.g.
dataGrid1.DataSource = null;
dataGrid1.DataSource = myArrayList;
I am sure there is a better way to do that and I guess it has to do with implementing a certain interface, but everything I found so far was quite confusing.
Does anyone have simple example code showing how to do it ?
thanks

There is a method on the DataGrid object called Refresh ().
Just call that in your code, and it should update the view.
In fact, there is a tutorial right here at the CodeProject, in which the author does something very similar to what you are doing (written for Managed C++ .NET).

Hello Developers,
I want to create a rotated font, and I use the following code to achieve this, like in this sample (http://winfx.msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_fxsamples/html/7c8b073b-5889-45e7-9a99-ebee39fe3b79.asp[^]), but using 1.1 framework.
Font CreateRotatedFont(int angle, Graphics g)
{
LOGFONT lf = new LOGFONT();
// scale a 12 point font for current screen DPI
lf.Height = (int)(-16f * g.DpiY / 96);
lf.Width = 0;
// rotation angle in tenths of degrees
lf.Escapement = angle * 10;
// Orientation == Escapement for mobile device OS
lf.Orientation = lf.Escapement;
lf.Weight = 0;
lf.Italic = 0;
lf.Underline = 0;
lf.StrikeOut = 0;
lf.CharSet = 0; //LogFontCharSet.Default;
lf.OutPrecision = 0;//LogFontPrecision.Default;
lf.ClipPrecision = 0;//LogFontClipPrecision.Default;
lf.Quality = 5;//LogFontQuality.ClearType;
lf.PitchAndFamily = 0;//LogFontPitchAndFamily.Default;
lf.FaceName = "Tahoma";
return System.Drawing.Font.FromLogFont(lf);
}
Am I doing something wrong in this code, or maybe someone did similar code once?
Thank you!

Hi,
I'm trying to work out the standard deviation of some numeric data in my form... but I can't see any way to call a StDev function. I've hunted high and low on the web and in the .Net help but I can't seem to find anything like this... can anybody make any suggestions as to how to do this?
TIA...
Mike

You can calculate StdDev is a simple loop.
1) Calculate the average of all values.
2) For each value X calculate DIFF = (X-AVG).
3) Square each DIFF value.
4) Sum the Squared DIFF values for the entire data set.
5) Divide the Sum of Squared DIFFs by (n-1) where n = number of values.
6) StdDev = Square Root of value calculated in Step 5.

Thanks so much for that - I really appreciate it... I'll give that a try when I get a chance to get back to that project.

G'day everyone,
I've tried to begin playing with smart device and pocket pc 2003 using VS .net 2003. I can begin a project, no problem, but when I try to debug, it comes up with an error...
One or more files from the Emulator for Windows CE installation is missing,
Please reinstall Emulator for Windows CE and try again.
Well, I've done that numerous times, even tried v 5.0 and 4.2, downloaded and installed just about every tool and sdk for the smartphone and pocket pc and still I get this error.
Im running VS 2003 and XP Pro.
Any ideas on how to get this to work would be great.
Cheers in advance.
Craig

Hi,
I know this is fundamental question, but simply I am beginer in WindowsForms.
In VCL in DragDrop events there are Sender and Source, but in WindowsForms there is only Sender. How can I obtain a Source?
TIA
|
|
|
|
|
|
Ok, an example:
I have two ListBox (list1, list2). I'm preparing the drag&drop functionality for this list. I know the basic. First I must do that then that ... So I move item from list1 to list2. Sender point at list2 (I think). In VCL Source point at list1. Is there any pointer in WindowsForms like the Source in VCL? Of course I know I can make a variable and on begining of the d'n'd I can keep the source object in this variable. I wonder if there is "pretty" way to obtain a source object.
TIA
|
|
|
|

Well I'm not the d'n'd specialist. But as I see it, I would do the following:
In the OnItemDrag event of list1 you call DoDragDrop(). As the data parameter of DoDragDrop() you set the ListItem that the user is dragging.
In the OnDragDrop method of List2 you have the sender object as well as DragEventArgs.
Sender is List2. DragEventArgs has a property Data with a method GetData() to get the object you passed in the DoDragDrop() method as Data parameter.
And I think that is what you need. Because that is your ListItem the user is dragging from List1 to List2 and that you have to add to List2 now. What do you need a reference to List1 for in this situation, it should be sufficient to have the reference to your ListItem.

richTextBoxResult->Find(System::Convert::ToString(textBoxSearch->Text),RichTextBoxFinds::WholeWord);
labelSearchResult->Text = System::Convert::ToString(a);
richTextBoxResult->SelectionColor = Color::Red;
richTextBoxResult->SelectionFont = new System::Drawing::Font(S"Microsoft Sans Serif",8.25f,FontStyle::Bold);
------------
Above, richBoxResult colors only one matched word and changes to Red. However, I need to change the color to red in all my strings. How do I do that? It seems I need to loop the stmts above.

You do realize this is the C# Forum and not the C++ Forum, right?
[EDIT]
Whoops! My mistake! I just came from the C# Forum.
Your code only finds one occurance of the text. If you want to find more, you'll have to start the Find over again after the occurance you've already found.
Ask this in the Managed C++ Forum[^]...

hi,
i want to use sqlserver mergemodule to install MS desktop engine,i've included the sqlsvr.msm into my deployment project
but i dont know how to pass install arguments such as password .if it is possible i would appriciate you helping me.
thanks.

Typically you set the userid and password when you build your database. In the VS.NET IDE add a textbox dialog and set up the properties to store the userid and password. Then configure the custom action that runs the script to create your database toi receive these property values and set the userid and password in your SQL script.

you are right but i want to set the password for "sa",during sqlserver installation from the setup file, i can determine the sa password and now i want to do so by merge modules.
thanks
|
|
|
|

I am not sure I understand why you would need to do this. You can run the built-in system stored procedure named sp_password to change the sa password from a script after a SQL Server is installed, so why would it matter if you set the sa password during the actual SQL Server installation itself, or if you set the sa password in a final custom action in the same package that installs the SQL Server?
The final result - setting the sa password - is the same in either case...???
In any case, a merge module is not a distinct physical entity in terms of an actual running setups. Merge modules cannot be "run" and do not exist as any sort of separate "setup". A Merge Module is nothing more than a set of Windows Installer tables and possibly CAB files. When you add a merge module to a Windows Installer package, what happens is the merge module tables are copied into the installer database along with any CAB files. The final result is a single MSI with additional table entries, not an MSI plus merge module components that are also run by the setup.
So you cannot change the behavior of a merge module by, for example, setting command line arguments.
The only way to change the behavior of a merge module is to manually author new functionality into the Windows Installer tables. Since a merge module becomes part of your final MSI, it does not make any difference if you change the merge module itself, or change your final MSI package after you've added the merge module. The net result is the same, because Windows Installer does not understand the concept of "running a merge module".
It would make more sense to change your final MSI package - which is essentially what I've already described: Add a dialog to collect the SQL Server parameters from the user interface and then run a script in a custom action that configures the SQL Server.
