trying to marshall over some data from an unmanaged dll, however i heard that the marshaller cannot marshall an array of structs, in a struct.
c++:
<br />
#pragma pack(1)<br />
typedef struct{<br />
unsigned short propCnt;<br />
PRO_PROPERTY prop[200]; <-- this sh*t here...<br />
} PRO_CHANGEDPROPERTY;<br />
#pragma pack()<br />
<br />
#pragma pack(1)<br />
typedef struct{<br />
long apiCode;<br />
PRO_DATA data;<br />
} PRO_PROPERTY;<br />
#pragma pack()<br />
c#:
<br />
[StructLayout(LayoutKind.Sequential, Pack = 1)]<br />
public unsafe struct ProChangedProperty<br />
{<br />
public UInt16 propCnt;<br />
[MarshalAs(UnmanagedType.Struct, SizeConst = 200)]<br />
public ProProperty[] prop;<br />
}<br />
[StructLayout(LayoutKind.Sequential, Pack = 1)]<br />
public struct ProProperty<br />
{<br />
public Int32 apiCode;<br />
public ProData data;<br />
}<br />
i cant seem to figure this one out, any help would be appreciated.

Hi All,
I have application to make and delete appointments.
Here is some code to make the appointments:
string myProp = "test";
Outlook.Application outlookApp = new Outlook.Application();
Outlook.AppointmentItem oAppointment = (Outlook.AppointmentItem)outlookApp.CreateItem (Outlook.OlItemType.olAppointmentItem);
oAppointment.Subject = "This is the subject for my appointment";
oAppointment.Body = "This is the body text for my appointment";
oAppointment.Location = "Bongerd 331";
oAppointment.Start = Convert.ToDateTime("31/01/2008 10:00:00 AM");
oAppointment.End = Convert.ToDateTime("31/01/2008 12:00:00 PM");
oAppointment.ReminderSet = true;
oAppointment.ReminderMinutesBeforeStart = 15;
oAppointment.UserProperties.Add(myProp, Microsoft.Office.Interop.Outlook.OlUserPropertyType.olText, true, System.Reflection.Missing.Value);
oAppointment.UserProperties[myProp].Value = "mijn";
oAppointment.Save();
and to delete :
String sCriteria;
string impNr = "mijn";
Outlook.Application oApp = new Outlook.Application();
Outlook.NameSpace oNS = (Outlook.NameSpace)oApp.GetNamespace("mapi");
Outlook.MAPIFolder oCalendar = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);
Outlook.Items oItems = (Outlook.Items)oCalendar.Items;
sCriteria = "[test] = '" + impNr + "'";
Outlook.Items oRestrictedItems = oItems.Restrict(sCriteria);
oRestrictedItems.IncludeRecurrences = true;
Outlook.AppointmentItem oAppointment;
Outlook.AppointmentItem oAppt;
oAppt = (Outlook.AppointmentItem)oRestrictedItems.GetFirst();
oAppt = (Outlook.AppointmentItem)oRestrictedItems.GetNext();
sCriteria = "[test] = '" + impNr + "'";
oAppointment = (Outlook.AppointmentItem)oItems.Find(sCriteria);
if (oAppointment is Outlook.AppointmentItem)
{
oAppointment.Delete();
}
else
MessageBox.Show("No object found");
it works fine for one appointment, bud the problem is that for making the appointments i have to use a Foreach loop (depending on some situations)..so there wil be always made more then one appointments and they get all the same userproperty value...bud now wen i click on 'delete' it deletes only one of the maded appointments...how can i make a loop to delete all appointments with same userproperty value???? maybe some code?
thanx

I have three panels one fills the app and the other you can drag into it, but I want to nest them to stay in one column, how do I do that?

Is this the same question from yesterday?
Take care,

Can some one point me in the direction of some example code that allows you to use multiple text colors for the text on a tree node.
I can find examples where the text foreground/background can be overridden for the complete string, but none that show how multiple colors can be used in the same string.
Many thanks
RK

Hi,
I haven't done this myself (for treeviews that is) but you will need to set the DrawMode
to TreeViewDrawMode.OwnerDrawText and provide a drawing handler. Google/MSDN will provide
the details, and I trust CodeProject holds articles using it too.

Do you mean modal? Use .Show() or .ShowDialog() depending on your needs.

Hi there,
Does anybody know how I can select the entire contents of a text box from the end to the start? (thus allowing the start to be displayed in the text box, if the text is too long to fit).
Below is (obviously) selecting from left to right:
this.txtName.SelectionStart = 0;<br />
this.txtName.SelectionLength = txtName.Text.Length;
so I need something like:
this.txtName.SelectionStart = txtName.Text.Length;<br />
this.txtName.SelectionEnd = 0;
but Text Box has no SelectionEnd Property...
Thanks!

I didn't test it but try something like
<br />
<br />
this.txtName.SelectAll();<br />
this.txtName.SelectionStart = 0;<br />
this.txtName.ScrollToCaret();<br />
I know this kind of problems (ever tried implementing syntaxhighlighting in a richttextbox ... well you wouldn't want to use the Selects! you will end using the RTF-code itself ... argh) - so I feel you pain

Thanks for this CKnig, but no joy

I cannot reproduce your problem. Specifically, calling this.txtName.SelectAll() outside of the constructor retains the current position of the text within the TextBox. This means that if you are scrolled to the start, then call .SelectAll(), you will still be at the start after the call. If this is not the case for you, please be more specific. If you are scrolling the text or selecting all of it in the constructor for your form, then move that code into the OnShown event for the Form. Good luck,

Thanks Jeff,
this.txtName.SelectionStart = 0;
Correctly sets the cursor position to 0, but when I add:
this.txtName.ScrollToCaret();<br />
this.txtName.SelectAll();
All text inside the textbox is selected, but the cursor position is now at the end of the selection..
Any ideas? Thanks.

Where in your code are you calling .SelectAll()? Are you calling it prior to the object being displayed? If so, then that is your problem. The GUI state of the textbox stores info about things like where to scroll. On my own computer running VS 2005 with .Net v2.0, I don't see this error at all, unless I make the .SelectAll() call from one of the following locations:
1. Within the constructor of any object that is initially loaded by the form
2. Within the Load() event of any object that is initially loaded by the form
3. Anytime the textbox is not visible If this still does not answer your question, then in your next post give me the stack trace from which you are calling the .SelectAll() method. Good luck,

hmmmm.. Thanks Jeff,
I'm calling it in the Enter event of the text box..
|
|
|
|
|
hmmm. I missed that one, but mine did finally do the same thing you described. I got it to work how you requested by doing the following:
textBox1_Enter(object sender, EventArgs e) {
textBox1.Select(textBox1.TextLength, -textBox1.TextLength);
}Hope this helps!

Hi guys,
I need your help. I am not a pro in C# and have stalled with a problem. My application does a bunch of things in the following function and this function is called when a button is clicked. upon clicking and upon execution of these functions my application background stalls/turns white due to I believe memory overloading. Please advice on what I could do to avoid that, I tried using application.doevents() but that causes then my MDI screen to go white  Please advice....
public bool ProcessMain(string []psfile,out string sErrMessage)
{
bool rt=true;
string ErrMessage=string.Empty;
sErrMessage=string.Empty;
try
{
rt=CleanBox(out ErrMessage);
if(rt)
{
rt=ParseFile(psfile,out ErrMessage);
if(rt)
{
rt=ProcessBatch(out ErrMessage);
if(rt)
{
rt=ProcessErrors(out ErrMessage);
if(rt)

Create a worker thread and run the method from there.

Thank you Justin,
Unfortunately I am clueless about threads, i researched google but can't figure out exactly on how to implement it with my code. Please advice

This article[^] is pretty simple, and straight forward. It has some sample code, with comments. It should be pretty easy to figure out, and then implement for your own needs. Good luck

Hey Csharp'ers.
I hope im in the right thread, so here goes...
Can anyone tell me if there are a certain sequence in witch these LDAP Attributes should be set ??
C - Country
L – Location
O – Organization
DC – Domain Component
OU – Organizational Unit
CN – Common Name
Example: [LDAP://CN=Domain Admins,CN=Users,DC=local,DC=mydomainname,DC=com] and so on
Because if i call the path above like this [LDAP://DC=local,DC=mydomainname,DC=com,CN=Domain Admins,CN=Users] (switch the DC and CN attributes) I get an unexpected error.
Do i have to set all the DC attributes last ??? or is there a certain sequence to use
