I am building an application in which I want to generate varialble amount of buttons on a windows form dynamically in run time...But since the size of the windows form is limited,I would like to use a scroll bar but I don't know how I can use it ..Can anyone help me please?
Best Regards,

It should be sufficient to assign true to the Form.AutoScroll property. If this property is set to true, scroll bars are displayed on the form if any controls are located outside the form's client region. Additionally, when autoscrolling is on, the client area of the form automatically scrolls to make the control with input focus visible.

I am trying to populate a treeView with the folders of my logical drives (this includes subfolders) so that it's almost like the format of Windows Explorer. I have checked various forums and MSDN, but that help is aimed more for advanced users. Does anyone know how to do this or a thread of how to do this?
Thanks!!

It would help if you told us what exactly are you having problems with...
The process itself is fairly straightforward, if you know how to use recursion.
You create a function where you have a directory and a TreeNode as parameter, let's say
void AddDirectoryNodes(TreeNode parent, string path)
In this function you get yourself a list of all subdirectories of path (the Directory class has a method for this).
For each subdirectory you create a new TreeNode (with the subdirectory's name as node name) and add it to parent's Nodes collection.
Then you call AddDirectoryNodes() from within itself with the newly added TreeNode as parent and the current subdirectory as path.
Voila, you get a nice tree structure of all directories.
Then all that remains is to enumerate all your drives, add a TreeNode for each drive and then call AddDirectoryNodes for these drive nodes.

Your pseudocode aided me in getting the final solution. THANK YOU!!
Here's the code for displaying all folders in your computer's logical drives in the windows explorer-style (assuming you have a hard drive C:\ and D:\:
string[] logical_drives = System.IO.Directory.GetLogicalDrives();
foreach(String drive_letter in logical_drives)
{
if(drive_letter.Equals("C:\\") || drive_letter.Equals("D:\\"))
{
TreeNode root_node = new TreeNode(drive_letter);
treeView1.Nodes.Add(root_node);
populateTreeView(drive_letter, root_node);
}
}
private void populateTreeView(string directory_name, TreeNode parent_node)
{
DirectoryInfo dir_info = new DirectoryInfo(directory_name);
DirectoryInfo[] directory_array = dir_info.GetDirectories();
foreach(DirectoryInfo current_directory in directory_array)
{
TreeNode new_node = new TreeNode(current_directory.Name);
parent_node.Nodes.Add(new_node);
if(current_directory.GetDirectories() != null)
populateTreeView(current_directory.FullName, new_node);
}
}
Now that I have the treeview filled with all the folders in my drives, I need to do 1 more thing. When I select a node, I write the full path of the node to a text file to save the path. When I reopen the application, I would like to have the same folder selected so I can resume my work in that folder. This is the code I would like to have, but it doesn't work:
StreamReader sr = new StreamReader("directory.txt");
if((line = sr.ReadLine()) != null && line != "")
{
treeView1.SelectedNode.FullPath = line;
sr.Close();
}
How can I select a given node at form load time?

Hi all,
I'm developing a custom DataGrid Column, that hosts a custom IPAddress Control.
I Should override the Paint mathod to paint the desiered text on the GridColumn
when the Paint method is called because the DataGrid USer clicks the last row in the grid to insert a new value.
i retrieve the value from the Column using "GetColumnValueAtRow ( source,rowNum )" and Paint it as shown in the code below.
i handled the problem of retrieving an invalid value but assign the NullText property that i previosly set.
But still the Paint draws 4 extra empty rows instead of only one.
anyway seems that i'm not handling the Paint method properly so does anyone knows how i should handle the Paint method when the User clicks on the last row in the DataGrid to insert a new value.
protected override void Paint
(
Graphics g,
Rectangle bounds,
CurrencyManager source,
int rowNum,
Brush backBrush,
Brush foreBrush,
bool alignToRight
)
{
try
{
string strIPAddress = "" ;
try
{
strIPAddress = ( string ) GetColumnValueAtRow ( source,
rowNum ) ;
}
catch
{
strIPAddress = this.NullText ;
}
Rectangle rect = bounds ;
g.FillRectangle ( backBrush,rect ) ;
rect.Offset ( 0, 2 ) ;
rect.Height -= 2 ;
g.DrawString ( strIPAddress ,
this.DataGridTableStyle.DataGrid.Font,
foreBrush,
rect ) ;
}
catch
{
System.Diagnostics.Debug.Assert ( false ) ;
}
}

when creating a windows service, I wanted to change the ServiceName property - in which IDE Properties window can I find the ServiceName property and change it to whatever name I want??
|
|
|
|
|
From the MSDN documentation.
The ServiceName identifies the service to the Service Control Manager. The value of this property must be identical to the name recorded for the service in the ServiceInstaller.ServiceName property of the corresponding installer class. In code, the ServiceName of the service is usually set in the main() function of the executable.
There isn't IDE support, you have to write code to set that value.

Create a deployment package. You can use either what's included with Visual Studio (check the Setup and Deployment Projects when you create a new project) or if you need added support check out products by InstallShield.com[^] or Wise[^]. Nullsoft also makes a nice installer package that is free, you can locate it here[^]

Hi,
I have a word document in a stream, and I want to get the plain text out of it. How can this be accomplished without creating an instance of Word? I dont want to have to save my memory stream to disk, open it with a instance of word, save it as text and then load that text into a memory stream, as I need to parse MANY files as quickly as possible! (Search engine indexing)
I found an example in JAVA but it uses loads of java imports that I have no experience in, so I am unable to translate:
http://java2.5341.com/msg/49663.html[^]
Thanks for your time.

There are a few options.
- Get the index plugin for office documents that index server uses and use that in your application
- Open office
- a thrid party library like aspose.word, google around there are a few

Is there a way to do this? There are no color properties for these controls. I guess I have to override some Windows messages to do so. Can someone point me in the right direction?
|
|

|

You create create a custom ScrollBar to handle this. Here[^] is an example, though it is done in VB.NET, it shouldn't require much to convert it over to C#.

Hi fellow CPians!
I'm having a hard time trying to create the C# declarations for several SAPI (MS Speech API) 4.0a interfaces, perhaps somebody can give me a litte tip...
Several interfaces deal with an obscure struct SRPHRASE, defined like this:
typedef struct {
DWORD dwSize;
BYTE abWords[0];
} SRPHRASEW, * PSRPHRASEW;Although abWords is declared as a BYTE array, the documentation states that abWords is "Memory containing a list of SRWORD structures, in temporal order".
SRWORD is defined like this:
typedef struct {
DWORD dwSize;
DWORD dwWordNum;
WCHAR szWord[ ];
} SRWORD, *PSRWORD;The idea behind this is to call the interface function ISRResBasic::PhraseGet
HRESULT PhraseGet(
DWORD dwRank,
PSRPHRASE pSRPhrase,
DWORD dwPhraseSize,
DWORD *pdwPhraseNeeded) where pSRPhrase's documentation reads: "[out] Address of an SRPHRASE structure to receive the phrase." and for dwPhraseSize: "[in] Number of bytes available in the structure specified by pSRPhrase. If the number is too small, PhraseGet returns SRERR_NOTENOUGHDATA and fills in pdwPhraseNeeded with the number of bytes needed."
So far I've tried declaring PhraseGet as:
void PhraseGet(UInt32 dwRank, ref SRPHRASEW pPsrPhrase, UInt32 dwPhraseSize, out UInt32 pdwPhraseNeeded); but no matter how I declare SRPHRASE, I always get a COM exception (HRESULT 0x800706C6) 
I don't know how to declare these structs in a way that they can be marshalled correctly.
Any hints would be appreciated!
Thanks in advance,
mav
