Hello!
I have the code below, but I really don´t know how to make it work in C#.
"Type" in C# is like "struct" ??
Should I use "ref BrouseInfo lpbi" in order to refer to my "struct" or "Type" in the SHBrowseForFolder calling and/or declaration???
Const BIF_RETURNONLYFSDIRS = 1
Const BIF_DONTGOBELOWDOMAIN = 2
Const MAX_PATH = 260
Private Declare Function SHBrowseForFolder Lib "shell32" ( _
lpbi As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32" ( _
ByVal pidList As Long, _
ByVal lpBuffer As String) As Long
Private Declare Function lstrcat Lib "kernel32" Alias "lstrcatA" ( _
ByVal lpString1 As String, _
ByVal lpString2 As String ) As Long
'Tipo para def
Private Type BrowseInfo
hWndOwner As Long
pIDLRoot As Long
pszDisplayName As Long
lpszTitle As Long
ulFlags As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type
nextcode :
Private Sub cmdSearchFolder_Click()
Dim lpIDList As Long
Dim sBuffer As String
Dim szTitle As String
Dim tBrowseInfo As BrowseInfo
'Personaliza a procura
szTitle = "Type the source folder for the search : "
With tBrowseInfo
.hWndOwner = Me.hWnd
.lpszTitle = lstrcat(szTitle, "")
.ulFlags = BIF_RETURNONLYFSDIRS + BIF_DONTGOBELOWDOMAIN
End With
lpIDList = SHBrowseForFolder(tBrowseInfo)
If (lpIDList) Then
sBuffer = Space(MAX_PATH)
SHGetPathFromIDList lpIDList, sBuffer
sBuffer = Left(sBuffer, InStr(sBuffer, vbNullChar) - 1)
'This is the Textbox
txtFolder.Text = sBuffer
End If
End Sub

Use System.Windows.Forms.FolderBrowserDialog

Hi there,
On a article posted related to Treelistview control(http://www.codeproject.com/cs/miscctrl/treelistview.asp) .In this example if i enable the checkbox property, all Items in this control display checkbox near to them .

can some one send me example so get the same functionality
Regard
Anilesh

Hi..
How could i make the installation (for my setup project) starts automatically when the user insert the CD that includs it(without open the CDROM directory)?
I am too late but i will never give up
|

Just add a file autorun.inf in your CD root directory.
For example : if your setup file is setup.exe, just add these line to your autorun.inf:
open=setup.exe

Hi,
I want to clone a compound object by MemoryStream.
I wrote the code in the following.
<code>
public object CloneAnObject(object objectToClone)
{
MemoryStream readStream = new MemoryStream();
BinaryFormatter binaryFormatter = new BinaryFormatter();
binaryFormatter.Serialize(readStream, objectToClone);
MemoryStream writeStream = new MemoryStream(readStream.GetBuffer());
return binaryFormatter.Deserialize(writeStream);
close(readStream);
close(wroteStream);
}
</code>
The code usually works well, but sometimes an IOException occurs.
In the help of MemoryStream.GetBuffer(), it seems the memoryStream should be closed before GetBuffer() is executed.
Thank you!

I want to know how long a particular function in my program takes to run. How can I get the number of milliseconds between two DateTime objects? Or is there a better way to do this?
|
|
|

I'm no .net expert so I can only give you the Win32 way.
Use QueryPerformanceCounter() and QueryPerformanceFrequency()
Very high resolution timer, I used it all the time when doing game development on Win32. Milliseconds aren't really good enough for this sort of timing btw.
|
|
|
|
|
try this (C#)..
double totalMillisecs = (dt2-dt1).TotalMilliseconds;

Thats what I was after. Thank you.

U can use the following idea..
int t1= Environment.TickCount;
function();
int t2=Environment.TickCount;
int t3=t2-t1;
Console.Writleln("Time consumed : " + t3.ToString());

Hi,
I would like my web app to output to a webpage via Response.Write() upon pageload... But i dont want it to just blurt it out at the top of tha page as it seems to always do.
Could anyone please tell me how I go about making sure my Response.Write() only outputs between given points/Html tags/etc?
It's not somthing i can simply output to a pre-placed text object as it contains HTML formatting which Response.Write handles and it must also output between specific CSS class tags to recive the correct formatting.
Is Response.Write() what i should be using? or is there another method i should consider?
Thanks

You can position labels in your HTML and set their text instead. Otherwise, you have no option. it's all to do with in what order the code is called.

If i want to select some icon or a part of text in word or visualstudio editor or select item in the itemlistbox i see a select blu rectangle.
How can use that in my application? i don't want to create it creating a alpha blu fillrectangle with gdi+.
But i want to use methods like ControlPaint
tnx

Which control do you use ?
if label, then you cannot select the text.
if textbox or richtextbox, then you can select the text using method "Select(int start, int length)".
e.g.
this.textbox.Select(0, 2);

a small problem
i have two forms one mainform and one frmtoolbar ,
mainform has a menuitem mnu1 and frmtoolbar has a button btn1
in the mainform i am calling frmtoolbar as follows
myToolbar = new frmToolbar();
this.AddOwnedForm(myToolbar);
myToolbar.Visible = false ;
myToolbar.Show();
i want to call menuitem mnu1 from mainform
on the button click event of frmToolbar the btn1
i am getting non - static field error if i make the menu item public in the main form
i am not sure if this can be solved using delegate
please give me an exxample if this is
thanks

In you're event handler for the button on the frmToolbar Form you can use the Owner property to access an instance of the MainForm. So something like this will work (in frmToolbar)
private void OnButtonClick(object sender, EventArgs e)
{
((MainForm)this.Owner).mnu1_Click(sender, e);
}
You're getting a non-static field error because (I'm taking a logical guess now) that you are referencing the class (hence you have to use a static property / method) when you really want to reference an instance of the class (and get member property / methods).
You don't need to use delegates, you're just not referencing an instance of the MainForm class.
You know you're a Land Rover owner when the best route from point A to point B is through the mud.

I have a repeater control to display thumbnail pictures. The itemtemplate is made of a web image control. When user clicks on the thumbnail picture, I want it to display a larger image in a web image control and display the image description in a label( the image description is saved in database).
My current code is :
I have a getPhoto function which will get the thumbnail pictures through IhttpHandler and bound to the repeater control.
Then I have a repPhotoG_ItemDataBound function, here I add the javascript to the image html control and call a javascript to pass the thumbnail imagename as parameter and show the large image.
Now, I can get the thubnail picture and display the large images, but I just don’t know how to get and display the image description. Please help!!
private void repPhotoG_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
//finding repeater item Image
System.Web.UI.HtmlControls.HtmlImage img=(System.Web.UI.HtmlControls.HtmlImage)e.Item.FindControl("iPhoto");
//create a relative path for image and add onclick function
img.Src=img.Src.Replace('\\', '/');
string Description="";
string Image;
Image=IMGpath(img.Src);
img.Attributes["onclick"]="showImg('"+Image+"')";
}
function showImg(imgName)
{
imgOn = ("" + imgName);
document.imgLarge.filters[0].Apply();
document.imgLarge.src = imgOn;
hdr.innerHTML=imgName;
document.imgLarge.filters[0].Play();

my project is to implement a basic inventory system using an array of structs.
the struct contains an int, itemNumber, and a method, AddItem.
if i create an array of 100 of the structs, it seems to mean i have 100 copies of the method.
i could make the method static but i'm limited to accessing only static members.
i'm wondering if there isn't a better way.
it seems i should keep AddItem in the same struct definition as itemNumber so i can make itemNumbers' access private.
with this scenario:
1) would i have 100 occurrences of AddItem?
2) is there a better approach than what i've outlined?
i appreciate any comments.
thanks.
matt

I'm really lost on why you have an AddItem method inside the struct. If you want the itemNumber to be read only, just set it in the constructor and have a property with only a getter. If you want to automatically increase the itemNumber, you can have another static number in the struct and when a new item is created, assign the itemNumber to the static number and increase the static number by one.
