Handle the keypress event, check the incoming character, and cancel the event if does not meet the requirements by setting Handled = true

Hello
I want to download one folder containing files from remote server to local computer. i am using vb.net. how should i do it? i have two possible ideas
1. Make zip file, down load to local machine and unzip
2. download files one by one using binary stream.
which one is perfect. if there is any other way?
Please Help
thanks

System.Net provides you support for this.
Basically, you have to create an instance of WebClient, and call DownloadFile() method, or OpenRead() to get a stream:
Dim client As WebClient = new WebClient()
client.DownloadFile(URL, "c:\test.zip")

Hi,
i have an application with my own Login-System.
When a user starts the app and loggs correct in,i want to store user-data in a class "Logininformation".
i have to access the Logininformation class in many other forms.
How could this be done ?
I know that global Vars are not allowed in C#, but how can i get this problem done ?
bye jogi

There are many ways to do it. You could persist the information, such in a database. You could also pass the information between forms (least favorable), or have a singleton object that is shared between the forms.

You can simply define the class as static. For example:
internal static class Logininformation {
private static string username;
...
internal static string UserName {
get {
return username;
}
set {
username = value;
}
}
...

I am in the middle of building an application in Visual studio 2005. For some reason I spend all my time going back to each form and having to resize and reformat. I dont know why. I have all forms Locked and controls Locked, but it does not matter it has a mind of its own. Is there a solution that I can do to fix this issue. I am a beginner but a little farther along.

Did you install Service Pack 1 for VS 2005??
|
|
|
|
|
|
No it was installed already... So that does not solve the issue. Any other suggestions.
|
|
|
|
|
Set the attributes of the *.Designer.cs file to "readonly" once you're done with a form. Do you have any plugins installed in VS2005?

Are you using native forms (System.Windows.Forms.Form) or custom inherited forms. I'm asking this because in many situations the derived form (or control) sets for example size or position in constructor and this would lead to the behaviour you described.
|

|
|

I have been exerimenting and searching for answers. I believe I may have fixed the issue. I have created one main form and I show all child forms in a panel of the main form. My font default for each form was different. When I changed the font of each form the sizes changed for the whole form. What caught my attention was a previous question in another forum was sub forms inheriting the parent forms formatting. So what I did is went through all the forms and panels changing the font to match the parent form. I only hope that this is the fix. So far so good. Thanks for all your suggestions!

Hello,
I'd like to change Windows system fonts dynamically and programmatically.
Like we do by right-clicking on the desktop, selecting "properties"->"Appearance" tab->listbox "Font size".
I found some information about the API SetupChangeFontSize, but it requires restarting the computer (and sometimes asks for the install CD), which isn't what I'm looking for.
I tried also to modify some registry keys/values under HKCU\Control Panel\Desktop\WindowMetrics, HKCU\Control Panel\Appearance.
Then sending a modification message to all the windows with SendMessageTimeout.
Without success.
Any idea?
Regards

Of course it does this. Those changes usually won't take effect until the system restarts.
You simply have no choice. A restart will be required to do this.

Then, if a restart is mandatory, how Windows does this when an user choose the menu?

We have a crystal report contains additional functions to get same text.
It works well if we exporting report to PDF file directly,
but display empty value if we preview report in Crystal Report Viewer.
We declare a global variable in one sub report,
it is a handle of an array, then we get same text from this global variable in other sub report.
any suggestion for this case?
Glad to discuss with you and best wishes.

Before the preview, is the ReportDocument.Refresh method called?
|
|
|
|
|
I tried add Refresh before preview, but it didn't work. 
Glad to discuss with you and best wishes.

Is this possible??
I've tried all manner of possibilites including (but not limited to):
- "File:///C:/MyApp.exe" args1 args2
- "File:///C:/MyApp.exe args1 args2"
- "File:///C:/MyApp.exe%20args1%20args2"
- %22File:///C:/MyApp.exe%22%20args1%20args2
also tried with forward slash and backslash.
Any help is appreciated,
Adam.

Isn't it done using siwtches? /p etc
or using the -
myapp.exe -arg1 -arg2
?
Those look vaguely familiar?
|

Are you doing this in command line or from a program?
In both cases, you could simply remove the File:///. If command line, otherwise it's fine but if from program using Process.Start, you must separate the program and the arguments and deliver them as different parameters to the start method.

I have a DataGridView binded to this table:
[Users]
ID Name
-- ----
11 Qwe
22 Asd
Grid is directly binded with a typed dataset.
I have a second table like this:
[Records]
ID UserID Data
-- ------ ----
67 11 ....
68 11 ....
Records.UserID is connected to Users with a foreign key.
What I want to do is: when the user doubleclicks User #11 I open a new grid, binded to Records table but only binded to rows where UserID = 11. Doubleclick, getting ID, new grid etc. those are I'm OK with. I wouldn't had any problems if I was doing this connected with sprocs but I want it to be binded and I simply have no idea how to do this.
Can you please give me any ideas?

I would use a dataview to service the records gridview.
When the user double clicks you set the rowfiler of the dataview
Dataview1.RowFilter = String.format("UserID = {0}",UserIDValue)
changing the filter of the dataview automatically updates the records gridview
Never underestimate the power of human stupidity
