HI,
I want to superimpose two picture boxes and make the top picture box image transparent.
Thanks in advance
|
|
|
|
|
What type of bitmap is in each of the two PictureBoxes: .png with transparency ? or ... ?
There are several ways you can approach this, and I suggest you start by reading/studying this CodeProject article: [^].
And, then, read the discussion here: [^].
If these references don't assist you to get what you want, then please post more details here, and describe what you've tried, and any error messages.

Looking for a simple example (with how to) for a USB plug in and unplug condition. I think I use VID PID?

For searching, use Google. It will point to this[^] article.

I want to write the regular expression for the below condition.
1. Allow only A to Z, a to z but not I,O,X and also not 0 to 9
Means if string have a character from I,O,X or digit then it should return false.
Would anyone please help me how to do this?

Try:
[A-HJ-TP-WYZa-z]*
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
|
|
|
|
|
Thanks for the reply but unfortunately it is not working for the below mentioned string
1. "I"
2. "IO"
3. ABCIO
4. IABCOX
In these type of strings, the result should be FALSE but using this expression [A-HJ-TP-WYZa-z]* it is giving TRUE.
|
|
|
|
|
And exactly how did you use it?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
|
|
|
|
|
I think anchoring the ends of the pattern that Griff gave will do what you want:
^[A-HJ-TP-WYZa-z]*$ This says that everything in the string must meet these conditions.
And if an empty string is not permitted, change the asterisk to plus:
^[A-HJ-TP-WYZa-z]+$
A positive attitude may not solve every problem, but it will annoy enough people to be worth the effort.
|
|
|
|
|
We both missed that the pattern itself was broken:
^[A-HJ-TP-WYZa-z]*$ should be:
^[A-HJ-NP-WYZa-z]*$
(The T should be N.)
A positive attitude may not solve every problem, but it will annoy enough people to be worth the effort.
|

See my reply to Griff's comment below.
(I should have replied here...)

I don't think there's "direct" way to do that unless you specify the characters in the expression.
Why not simply use [IOX0-9]+ and invert the match condition?
[EDIT]
Of course you will need to handle the case with the lower case characters - either with RegexOptions.IgnoreCase flag or by specifying appropriate characters in the expression itself.
[/EDIT]
Your time will come, if you let it be right.

The anchored expression I gave yesterday (the fixed one with N for T...) works when I test it in Expresso.
It matches only A-Z (except IOX), any lowercase a-z, no digits.
If punctuation is to be allowed, then the negated character class construct would work:
^[^IOX0-9]+$ will fail any string that contains uppercase I,O,X or any digit. Anything else would be allowed.
A positive attitude may not solve every problem, but it will annoy enough people to be worth the effort.

Of course that would allow "A&A" which doesn't fit the requirements.

I am new to programming in general and i am working on a creating a macro for Revit 2015. I was able to create the following coding that builds a solution correctly without any errors in Sharpdevelop, but when i run the macro within Revit i get an error. Any help or incite would be greatly appreciated.
Thanks

How do you think we can imagine what the error in "Revit" might be ?
I wonder why you aren't asking the question here: [^].

Then you have chosen a nice complex way to learn.
There'll be an exception, at which point Revit gives a general message. Add a try-catch and log the entire exception (write ex.ToString() to file)
It might be that the document is not set correctly (could be null), that the parameter doesn't exist, or something else. Logging the exception will tell you what went wrong, and where.
Alternatively, you can debug by attaching the IDE to the Revit-process.

String dcandle = cc[i];
Debug.WriteLine(string.Format("pids1:{0},Count{1}, datetime:{2}: ticks:{3}", k * 100 + i, cc.Count(), ck[i], cc[i]));
}
}
Question is at the end of the loop i shall get 6 members in both odd and even minute
whereas due to some error i am getting 12 members in all/both odd and even key outer dictionary help
Here is output in debug windows
pids1:700100,Count1, datetime:12/10/2014 6:39:07 AM: ticks:odd ok
even key results:
pids1:700000,Count2, datetime:12/10/2014 6:39:07 AM: ticks:odd not ok
pids1:700001,Count2, datetime:12/10/2014 6:40:07 AM: ticks:even ok
odd key results:
pids1:700100,Count3, datetime:12/10/2014 6:39:07 AM: ticks:odd ok
pids1:700101,Count3, datetime:12/10/2014 6:40:07 AM: ticks:even not ok
pids1:700102,Count3, datetime:12/10/2014 6:41:07 AM: ticks:odd ok
The problem continue's so on till all loops as odd and even keys appear in both key values!?? which is not desired and only odd key should have odd values and even key even values
pids1:700000,Count4, datetime:12/10/2014 6:39:07 AM: ticks:odd
pids1:700001,Count4, datetime:12/10/2014 6:40:07 AM: ticks:even
pids1:700002,Count4, datetime:12/10/2014 6:41:07 AM: ticks:odd
pids1:700003,Count4, datetime:12/10/2014 6:42:07 AM: ticks:even

Please format your code properly. Also, what is your question?

now code is working when i replaced line
Cnestedict5.TryAdd(mk, cd); Cnestedict5.TryAdd(nk, cd);
with corrected one (Answer)
Cnestedict5.TryAdd(mk, new ConcurrentDictionary<DateTime, string>()); Cnestedict5.TryAdd(nk, new ConcurrentDictionary<DateTime, string>());
Thanks to all those who came forward to help me solve this problem

Hi,
I have a situation where I need to show data from database to textboxes. These textboxes has to be dynamically created and can be editable. I am able to create textboxes as follows:
string[] myData = liD1.ToArray();
public void showData()
{
for (int i = 0; i < myData.Length; i++)
{
if (txtMore.FindControl("txtD1StartTime" + i) == null)
{
txtStart1 = new TextBox();
lblStart1 = new Label();
txtStart1.ID = "txtD1S" + i;
lblStart1.ID = "lblD1S" + i;
txtStart1.Text = myData[i].ToString();
lblStart1.AssociatedControlID = txtStart1.ID;
lblStart1.Text = "Data" + i;
txtMore.Controls.Add(lblStart1);
txtMore.Controls.Add(txtStart1);
}
}
}
In my ascx page, I am loading those textboxes in
as follows:
<ul class="txtMore" id="txtMore" runat="server">
</ul>
showData() function is loading data with dynamically created textboxes. This is working fine. Now If i edit textboxes and try to get new data, it is not giving me anything. Actually it couldn't even find that control. Code is as shown below:
public void getData()
{
for (int i = 0; i < myData.Length; i++)
{
TextBox t = txtMore.FindControl("txtD1S" + i) as TextBox;
if (t != null)
{
string temp = t.Text;
}
}
}
Even though I have dynamically loaded textboxes from showData(), in getData(),it is not able to find any control. Please help.

I'm trying to read the buffer modified by the native function ntQueryEaFile.
Here is it's definition :
NTSTATUS NtQueryEaFile
(
HANDLE hFile,
PIO_STATUS_BLOCK iosb,
PVOID buffer,
ULONG length,
BOOLEAN single_entry,
PVOID ea_list,
ULONG ea_list_len,
PULONG ea_index,
BOOLEAN restart
)
I'm having trouble with the PVOID buffer (output buffer). The description reads :
"Caller's allocated buffer for output data. See FILE_FULL_EA_INFORMATION for detailed description of fields avaiable in buffer."
Here is the C++ def of this struct:
typedef struct _FILE_FULL_EA_INFORMATION {
ULONG NextEntryOffset;
UCHAR Flags;
UCHAR EaNameLength;
USHORT EaValueLength;
CHAR EaName[1];
} FILE_FULL_EA_INFORMATION, *PFILE_FULL_EA_INFORMATION;
Now my C# code:
[DllImport("ntdll.dll")]
public static extern uint NtQueryEaFile(
Microsoft.Win32.SafeHandles.SafeFileHandle handle,
ref IO_STATUS_BLOCK iosb,
out IntPtr buffer,
uint length,
byte single_entry,
IntPtr eaList,
uint ea_list_len,
IntPtr ea_index,
byte restart
);
public struct FILE_FULL_EA_INFORMATION
{
public uint NextEntryOffset;
public byte Flags;
public byte EaNameLength;
public ushort EaValueLength;
[System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.ByValTStr, SizeConst = 1)]
public string EaName;
}
public const int MAX_EA_NAME_LEN = 256;
public const int MAX_EA_VALUE_LEN = 65536;
and the function call :
FILE_FULL_EA_INFORMATION FEAI = new FILE_FULL_EA_INFORMATION();
int EA_BUFSIZ = Marshal.SizeOf(FEAI) + MAX_EA_NAME_LEN + MAX_EA_VALUE_LEN;
IntPtr p_FEAI = Marshal.AllocHGlobal(EA_BUFSIZ);
Marshal.StructureToPtr(FEAI, p_FEAI, false);
status = NtQueryEaFile(hFile, ref ioStatusBlock, out p_FEAI, System.Convert.ToUInt32(EA_BUFSIZ), returnSingleEntry, IntPtr.Zero, 0, IntPtr.Zero, restartScan);
status returns
0xC0000005
STATUS_ACCESS_VIOLATION
Any ideas how to fix this ? Thanks for your help !
