Determine How Many Milliseconds I Need To "Sleep" For In Order To "emulate" 2 Mhz Speed?
Oct 15, 2009
Is there a simple way to determine how many milliseconds I need to "Sleep" for in order to "emulate" a 2 mhz speed. In other words, I want to execute an instruction, call System.Threading.Thread.Sleep() function for an X amount of milliseconds in order to emulate 2 mhz. This doesn't need to be exact to the millisecond, but is there a ball park I can get? Some forumlate that divides the PC clock speed by the 2 mhz or something?

Currently I'm using System.Threading.Thread.Sleep(5000) to let my app pause/sleep for some time. This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this. I also tried using a timer but that didn't work out to well for me..

i want to check for the lan speed and put this speed value in a progress bar.
for example:
[==== ] the lan speed now is 23 KB/s
and there is another problem is if there are a LAN and a WiFi adapter in the same time how do i check for the speed for both adapters

I'm working on a client application (server is out of my control) that connects to a server and exchanges query/command datagrams. 'Milliseconds Count!' according to my project specification, meaning that the more we can shave off a send/receive process the better.
I understand that there are physical limitations like network bandwidth, internet latency, etc. Even so, I have a strong gut feeling that a lot of the latency I'm seeing is directly related to processing; it seems 'out of phase' from the latency of other network operations (albeit with significantly smaller datagrams). IE: A standard 32 byte Windows Ping returns in about 5ms consistently, our query/response datagram (468 bytes out, 1500 bytes back) returns in about 15ms consistently.
I'm also working with multiple threads to speed things up as much as possible at the client side, and it seems the more threads are involved the more latency is generated (I've seen up to 70ms of additional lag when using 3 threads as opposed to 2). In a recent Google I found something that I only glanced at, that said something about a limitation in Windows System Timing where some claim was made that any System.TimeSpan < 10ms was effectively going to be a 10ms Timespan because the Windows System Clock only 'Ticks' every 10ms. I wasn't paying attention at the time, but now I'm afraid it might be relevant and I can't find it again.

As we know when a column divider is double clicked the column width resizes itself to fit its contents. How can we emulate this behavior with code?

Trying to setup a VB array (jagged array?) that has an entry for each rcd that contains the # of bytes in the data, as well the data. If it's possible how do you setup and loop through something like this is VB?
EX (1024 max bytes of data but it could vary):
struct inpRcd {
int rcdSize;
byte data[MAX_RCD_BYTES];
} inpRcds[MAX_RCDS]

Visual Basic 6 had the Text Box Array that worked great.It no longer exists(in the same form) in either Visual Basic 20085 or 2010.I know that there are work-arounds that emulate the Text Box array but these are certainly not as easy to use as the version 6 Text Box Array.
In Visual Basic 2010 there is a tool box item that can be added, called Text Box Array. However, this does not place a Text Box on the form and I can't find any explanation of how to use it.what adding this to a form accomplishes and how to use it?

I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?

I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.

I have a value which is milliseconds, I did some experimenting, and with my very limited math skill I came up with this:
Dim val = _Memory.ReadValueFromAddress(hProcess, timer_addr, 4)
Dim seconds = val / 60 Mod 60
Dim minutes = val / 60 / 60
I don't even know what will happen when the hour counts down,

I am pulling a single field from a SQL Server 2008 table and when performing the SELECT in Management Studio, the result shows as:
2011-08-03 17:46:36.997
Now, in my application I'm storing that returned result as a string and using it to later perform an INSERT using it. I notice that after INSERTing into the database, I can see it is being stored as:
2011-08-03 17:46:36.000
Appears to be stripping off the milliseconds and replacing it with 000. In my case, milliseconds are important (sequencing thing)
