- Boxing information required Hi Dave The object is set and the list has a count of over 0, did not add those for the purpose of the thread. 3) the holder will not be in the same memory place, but I was wondering about the reference it would be containing. From the previous reply I get it that the references would be the same. 4) Isn't boxing the action of putting objects inside structures or objects (If not gotta go check my def of boxing) Regards, Chryso Tag: use of Debug folder's Database ?????

- Best storage practices For relatively small amounts of data you can play around with serialized ADO.Net Datasets, this can give you basic SQL-like functionality with no cost. Other options are to look at something like MSDE (2000) One combination I've used before was to develop an SQL Server database using SQL Server Developer Edition (includes Enterprise Manager, Query Analyser, etc.) then deploying the scripts to an MSDE instance. If you don't need heavy concurrent data access then MSDE should be more than enough grunt. Tag: use of Debug folder's Database ?????

- Get the running instance of the program!! Hello, How to get the the current running instance of my application when i execute the application Like MSN Messenger, if i run one instance of it, then any trial to execute the program will activate the current instance!! I know some techniques to ristrict programs to run only 1 instance but how to get to this instance My program is used to watch created file, so it runs invisibly as the system starts to monitor the created files on my hard drives, now i want to allow users to activate the hidden instance when they press shortcut keys like CTRL+ALT+1 Thanks a lot Tag: use of Debug folder's Database ?????

- Algorithm for getting a value from a dynamic logarithmic scale? Wow, thanks a lot for dedicating so much time to my little problem! I didn't notice anyone had replied here, so I just used this function: public static double Scale( double value, double base1, double base2) { return ( Math . Log(value, base1) * Math . Pow(value, base2)) / 10D ; } And fed it with two "base" values I calculated beforehand in another application. However, this doesn't really work as I described, and your solution sounds very interesting!! Please do continue if you have the time, I would very much like to try out the resulting function! Is it possible to implement the maxvalue as described Thanks, //Sire Tag: use of Debug folder's Database ?????

- Modifying an exception by ref? Thanks boban, that would work well, but in my case I don't want the caller of Retry to have to do special things with the exception. Inside OnException though, I can add a ref bool that indicates whether it is wrappering the exception. Then in retry I will be able to conditionally "throw;" or "throw ex;" where appreopriate. My version is not any more elegant, but I prefer to have the use of Retry be elegant, and the cludgy things be hidden away inside it. This is the final implementation: #region Retry generics /// <summary> /// A delegate that returns type T /// </summary> /// <typeparam name="T">The type to be returned.</typeparam> /// <returns></returns> public delegate T Func<T>(); /// <summary> /// An exception handler that returns false if Exception should be propogated /// or true if it should be ignored. /// </summary> /// <returns>A indicater of whether an exception should be ignored(true) or propogated(false).</returns> public delegate bool OnException(ref Exception ex, ref bool rethrow); /// <summary> /// Repeatedly executes retryThis until it executes successfully with /// an exception, maxTries is reached, or onException returns false. /// If retryThis is succesful, then its return value is returned by RetryUntil. /// </summary> /// <typeparam name="T">The type returned by retryThis, and subsequently returned by RetryUntil</typeparam> /// <param name="retryThis">The delegate to be called until success or until break condition.</param> /// <param name="onException">Exception handler that can be implemented to perform logging, /// notify user, and indicates whether retrying should continue. Return of true indicates /// ignore exception and continue execution, and false indicates break retrying and the /// exception will be propogated.</param> /// <param name="maxTries">Once retryThis has been called unsuccessfully <c>maxTries</c> times, then the exception is propagated. /// If maxTries is zero, then it will retry forever until success. /// </param> /// <returns>The value returned by retryThis on successful execution.</returns> public static T RetryUntil<T>(Func<T> retryThis, OnException onException, int maxTries) { //loop will run until either no exception occurs, or an exception is propogated(see catch block) int i = 0; while(true) { try { return retryThis(); } catch ( Exception ex ) { bool rethrow =false;//by default don't rethrow, just throw; to preserve stack trace if ( (i + 1) == maxTries ) {//if on last try, propogate exception throw; } else if (onException(ref ex, ref rethrow)) { if (maxTries != 0) {//if not infinite retries ++i; } continue;//ignore exception and continue } else { if (rethrow) { throw ex;//propogate exception } else {//else preserve stack trace throw; } } } } } /// <summary> /// Repeatedly executes retryThis until it executes successfully with /// an exception, or onException returns false. /// If retryThis is succesful, then its return value is returned by RetryUntil. /// This function will run infinitly until success or onException returns false. /// </summary> /// <typeparam name="T">The type returned by retryThis, and subsequently returned by RetryUntil</typeparam> /// <param name="retryThis">The delegate to be called until success or until break condition.</param> /// <param name="onException">Exception handler that can be implemented to perform logging, /// notify user, and indicates whether retrying should continue.

- Order of properties, methods I personally put my privates after my publics (which I also used to do with my C++ classes). My rationale for this is that when a user is looking at my source code to see how to use the class, they will look at the public part. If the publics are near the top, they won't have to scroll past a load of private implementation details to find them. (I also use #regions to separate out the public/private bits, so if someone has got outlining turned on the order is less significant, of course.) Tag: use of Debug folder's Database ?????

- Importing virtual functions from a Dll I'm using VS2005 and I'm trying to import a bunch of unmanaged classes from a dll. The DllImport attribute, requires you to declare you methods as static extern, however that does not mix well with virtual functions. I'm getting the following error: "Error 1 A static member CreateSignatureForSinglePackage(out byte[], int, out byte[])' cannot be marked as override, virtual, or abstract" With pure virtual functions, instead of importing them from the Dll I declared them locally with an empty body, however if I use that same approach with "normal" virtual functions, I'll loose the code in the base version.

- Clearing class instance Navaneeth wrote: Thanks but, it's foolishness to do so. Because I can catch that exception where I am invoking the class and I can continue using the object. Throwing an exception won't make the class instance not usable. No you can't continue using the object, because you will not have a reference to it if the constructor throws, even if you cantch the exception. Tag: use of Debug folder's Database ?????

- Datetime problems... Hi, I am trying to set up a scheduling type of function in a web application using c#. Basically, the user picks a date on a calendar and then selects an option in a dropdownlist. The dropdownlist is populated like: 00:30 01:30 02:00 and so on.... I then take that data and insert it into a sql database as 1 column. I first tried parsing to strings etc but ran into a whole heap of problems. Now i'm simply truying: // Get the date and times selected dtSelected = Calendar1.SelectedDate; dtSelected = DateTime .Parse(DropDownList1.SelectedItem.Text); This seems to reset the date part back to its default. So for example, when the screen loads i tell the calendar to display today: // Initial page load events if (!IsPostBack) { // Set the calendar and label for currently selected date Calendar1.SelectedDate = DateTime .Today; Label1.Text = Calendar1.SelectedDate.ToShortDateString(); dtSelected = Calendar1.SelectedDate; } If the user selects another date, then the date doesnt change when submitted. What is the easiest way to do this Have a calendar, and a dropdown list of times. Then create a datetime type and assign a date to it, and then add just the time onto the end Thanks!

- Converting from unsigned char* to Bitmap Hello all, I'm having trouble converting an unsigned char* into a Bitmap image. I have an unsigned char* in managed c++ code, which points to a 1280x1024 image with 8bppIndexed as the pixel format. When I display the image using the raw unsigned char* I'm getting the right image. In order to display the image on a C# console window, I need to convert the image from my C++ code in a System: rawing::Bitmap object. To do this, I have attempted to cast the pointer to IntPtr: IntPtr a_image_data = (IntPtr) const_cast < unsigned char *>( image_data ); //image_data is the unsigned char* I then used a delegate and event pair to send this IntPtr to the C# side of my project, and it retains the same IntPtr value. When I recreate the image using the IntPtr, it gives me an unrelated image. System.Drawing. Bitmap RetrievedImage = new System.Drawing. Bitmap (1280, 1024, 8, System.Drawing.Imaging. PixelFormat .Format8bppIndexed, ImageData); //ImageData is the IntPtr boxPic.Image = RetrievedImage ; //Display the image in PictureBox I think there is a problem in the casting. Please advise.

- Implied decimal point and decimal.TryParse The sales data coming from the mainframe does not have an actual decimal point in it. It is an implied position based on the how the column is set up. So, if I see a value of "56328099" I don't know by looking at it if that's 56328099M, 563280.99M, 5632.8099M or even .56328099M I have a handy dandy data dictionary that tells me for each field, how many decimal places it should have. The code I am attempting to clean up explicitly adds in the decimal value early on the process and only at the end, does it actually convert it over to an actual decimal value. Technically, all of this is within SSIS but I thought a single custom component would be better and less error prone than cutting and pasting an expression for many, many columns (I'm at a financial institution). Rather than write custom code on how to insert the decimal place and then calling the TryParse method, I thought I'd see if I could accomplish the same feat using a single call to the method with the appropriate formatters. That provide more insight into what I am attempting to do and why Tag: use of Debug folder's Database ?????

Re: use of Debug folder's Database ?????

Let me know if I've misunderstood you and did not answer your question.
I'm not sure I follow what you're asking... but, you usually add the MDB file to the project and mark it as "content". Content files will automatically be copied to the appropriate bin folder (Debug/Release/etc.). You can then access the file within the same directory as the application. Otherwise you have to use a fixed path and put the MDB file somewhere specific.

Peter, then why there is difference to give connection to local copy database(.mdb) and debug copy database(.mdb).
My real problem is :
i have used DataBinding Method through DATASET DESIGNER (FROM MSDN LINK: ms-help://MS.MSDNQTR.v80.en/MS.MSDN.v80/MS.VisualStudio.v80.en/dv_raddata/html/12360f54-db6c-45d2-a91f-fee43214b555.htm)
but update is not updating to local copy database so my toutor has suggest me do this step. And it is work . I want to know the
real result behind that.
1. i have connect database(.mdb) through local copy .
2. then i have run it. so i have copy of Database in the Debug folder.
3. now i have modify the connection of Database to the Debug folder.
4. then set properties of Database: Copy to output Directory is set to Copy if newer
plz tell me what is the real result behind that.
peter i am waiting for you.

The problem with putting the MDB as content is that it is copied to the bin directory on every build. If you modify the MDB in the application those modifications will be overwritten by the next build (the copy).
