  • .Net User Messaging System

    - by bechbd
    I am wondering if there is a framework out there for .NET to help me with sending messages to users. I would love to be able to write all my messages to a single repository. I would then like to be able to send these messages out to a user based on preferences that they set. e.g. I would like to be able to send a Notification A out to user A via email and text message and send Notification B to user B via SMS and IM. Any thoughts on if something like this exists or would I need to write it?

  • .Net System.Mail.Message adding multiple "To" addresses

    - by Matt Dawdy
    I just hit something I think is inconsistent, and wanted to see if I'm doing something wrong, if I'm an idiot, or... MailMessage msg = new MailMessage(); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); Really only sends this email to 1 person, the last one. To add multiples I have to do this: msg.To.Add("[email protected],[email protected],[email protected],[email protected]"); I don't get it. I thought I was adding multiple people to the "To" address collection, but what I was doing was replacing it. I think I just realized my error -- to add one item to the collection, use .To.Add(new MailAddress("[email protected]")) If you use just a string, it replaces everything it had in its list. Ugh. I'd consider this a rather large gotcha! Since I answered my own question, but I think this is of value to have in the stackoverflow archive, I'll still ask it. Maybe someone even has an idea of other traps that you can fall into.

  • Restore Emacs Session/Desktop

    - by Patrick McLaren
    I've been searching for how to restore an emacs session, with no luck. I'm looking to restore all previously open buffers, some of which might contain erc, shells, directory listings, files, etc. Every time I open emacs, I spend a considerable amount of time arranging my buffers; splitting them into rows and columns, opening a shell, arranging irc channels. It takes a while to get onto work. I've tried adding the following to my init.el (desktop-save-mode 1) And then using M-x desktop-save. This only seems to restore files that are open, not shells or anything else running within buffers. I've also checked the following questions (sorry, not able to post links yet): Session management in emacs using Desktop library Emacs session / projects / window management Emacs: reopen buffers from last session on startup? And read through: DeskTop and EmacsSession at emacswiki.org/emacs/SessionManagement Here's a screenshot example of my emacs session. A simple answer would be to just focus on real work :P

  • C system calls open / read / write / close problem.

    - by Andrei Ciobanu
    Hello, given the following code (it's supposed to write "hellowolrd" in a "helloworld" file, and then read the text): #include <fcntl.h> #include <sys/types.h> #include <sys/stat.h> #define FNAME "helloworld" int main(){ int filedes, nbytes; char buf[128]; /* Creates a file */ if((filedes=open(FNAME, O_CREAT | O_EXCL | O_WRONLY | O_APPEND, S_IRUSR | S_IWUSR)) == -1){ write(2, "Error1\n", 7); } /* Writes hellow world to file */ if(write(filedes, FNAME, 10) != 10) write(2, "Error2\n", 7); /* Close file */ close(filedes); if((filedes = open(FNAME, O_RDONLY))==-1) write(2, "Error3\n", 7); /* Prints file contents on screen */ if((nbytes=read(filedes, buf, 128)) == -1) write(2, "Error4\n", 7); if(write(1, buf, nbytes) != nbytes) write(2, "Error5\n", 7); /* Close rile afte read */ close(filedes); return (0); } The first time i run the program, the output is: helloworld After that every time I to run the program, the output is: Error1 Error2 helloworld I don't understand why the text isn't appended, as I've specified the O_APPEND file. Is it because I've included O_CREAT ? It the file is already created, shouldn't O_CREAT be ignored ?

  • Naive question of memory references in Operating system

    - by darkie15
    Hi All, I am learning memory references pertaining to Operating systems and don't seem to get to the crux of understanding it. For example, I am not able to visualize this scenario properly: "A 36 bit address employs both paging and segmentation. Both PTE and STE are 4 bytes each". How are they related? I can guess that this question might be too simple for many. But any help understanding the above basic concept would be appreciable. Regards, darkie15

  • choose append to existing backup instead of overwrite

    - by aron
    Hello, I have a database and I made it's first backup 2 days ago. Then yesterday I spent an entire adding new records. This morning I ran a backup, (but I selected append to existing backup set) as pictured below. I just ran a restore and I found that it wiped out all my data from yesterday and it restored it from the backup of 2 days ago. Not the version from this mornings backup. I zipped this backup file to be safe. I changed some data in the DB, Then I ran the back up again, but this time I selected "overwrite all existing backup sets" Now when I restore the db it's seems to restore the data from the backup correctly. I think I learned a lesson here, correctly if I'm wrong My questions is, Did I lose an entire day of work? I still have this morning's backup .bak file safe in a zip. Is there anyway I can restore is with the right data?

  • Operating System Widget Side Project

    - by Calpis
    I want to start on a side project and here's my idea: Whenever the user's mouse is pressed down, I want a small ring around the cursor to show up. I'm mainly doing this to learn more about programming and get myself to think outside of work related materials. My questions are: 1) is there a good source I can reference to start a project that deals with something like this? 2) Is visual studio a sufficient software to create such an application? Or would I need some other tool to do this. 3) What language should I choose to do this task? Thanks in advance!

  • wp7 odata v2 dataservicestate save and restore methods tombstoning example needed

    - by MIantosca
    I am looking for an example of how to use the new DataServiceState Save and Restore methods in a WP7 application in order to tombstone a datacontext - I cannot find any examples and the approach I used resulted in an exception this saves the data context correctly PhoneApplicationService.Current.State["DataContext"] = DataServiceState.Save(this.Model.Entities); this attempts to restore it after the app is re-activated var dc = (PhoneApplicationService.Current.State["DataContext"] as DataServiceState).Restore(); but throws an exception An item could not be added to the collection. When items in a DataServiceCollection are tracked by the DataServiceContext, new items cannot be added before items have been loaded into the collection. This is the same exception I get if I try to reload a datacontext that I stored "directly" (without using the DataServiceState.Save method) in the PhoneApplicationService.Current.State. I cannot find any offical documentation on the new ODATA v2 DataServiceState class or examples. thanks Michael

  • How can I create two partitions and clone one to the other (using Clonezilla)?

    - by johnny
    I was hoping someone could help. I want to create a "backup" partition. I want to create two partitions on my drive. One is a good install, which I want to then use clonezilla to copy the good partition to the broken/unused partition and have the restored partition boot up as usual. Example, C: goes bad. D: is a "good" copy of C. C gets a corrupt registry. I restore D to C, C will then boot up as usual. So, I need to do the clone with Clonezilla and the restore with the same. I see the part_...clone and restore. Will this do it? How do I get the partitions? EDIT: I am using XP. How can I do this? Also, I know this is not the best thing for all occasions. I have a offline backup as well. I would like to have both. Thanks for any help. I'm using Clonezilla if it matters.

  • How to restore a dd overwritten disk partition?

    - by DairyKnight
    First of all, I admit I'm stupid and I didn't run proper backup of my data, but you know crap happens... So, I've used dd to overwrite the first 2GB of my 750GB NTFS partition with a FAT32 partition. I've run Photorec and EasyRecovery but all I can restore is the 2GB FAT32 partition and the files on that. Is there a way to "roll back" to the NTFS paritition, and recover - at least - some part of the 750GB data? Thanks.

  • how to restore files deleted in the Mapping virtual drive

    - by r9r9r9
    I used psubst drive1: drive2:path /P to create the persistent virtual drive, I found that's greate, but when I delete files in those drives, they didn't appeared in the Recycle Bin, so How can I restore them? ex: I used (p)subst K: C:/1 to create the K: driver, then I delete files in the K:, I think it will be better if they are moved to the C:/Recycle Bin but not delete persistently. you can find more detail about psubst here: http://code.google.com/p/psubst/

  • sfdisk restore partition table if two hardisk have different sizes

    - by MA1
    What will happen if i try to restore the partition table of a larger hard disk to smaller hard disk, for example: partition table of 250GB hard disk to a 80GB hard disk using sfdisk like this. sfdisk /dev/sda < PartitionTable250.txt Will sfdisk detect it? I think there will be no problem if the partition table of a smaller hard disk is going to be restored on a larger hard disk?
