  • WPF deployment strategy dilemma.clickonce(limited customization)+autoupdate vs installer(unlimited c

    - by black sensei
    Hello Experts!!! I've been facing a deployment problem.I've built a WPF application with visual studio 2008 and created an installer(msi) which works fine.But then it's pain to add automatic update to it. i've seen this article at windowsclient.net but it seems to be pretty old but could have been the perfect thing for me.Then i looked at the .Net Application updater block v2.0 which uses enterprise library june 2005 and for some reason it's not installing on my machine. I thought i will need to use a more recent Enterprise library so i installed and compiled Enterprise 4.1(october 2008) but nothing better happened.To i decided to give a try to CLickonce deployment.After struggling with it, it was almost perfect.I realized that when i was testing the updates provided by the clickonce on my machine which is XP i didn't notice the need of having sqlite dll in the GAC. surely it was already there.I noticed it when i moved to vista that there is a problem.After checking the net i know it's impossible to add a dll to the Global Assembly Cache. Now i'm stuck, i think i've hit a wall.Can any one share some of his experience? I'm willing to try the updater block if i can get help. Thanks for reading this!!

  • Limited options for accessing events in derived classes?

    - by maxp
    Im refactoring a class, and moving sections into a base class. I have a few events similar to public event EventHandler GridBinding; Which are now in the base class, but i am finding i cannot now check to see if the event is null in my derived class. Doing so gives me the error: The event 'xyz.GridBinding' can only appear on the left hand side of += or -= (except when used from within the type 'xyz._MyBaseClass'). Is this correct, am i missing anything, or is there any way to get around this or is writing an accessor the only way to do this? I am using c#/.net 4.0

  • SQLAlchemy - relationship limited on more than just the foreign key

    - by Marian
    I have a wiki db layout with Page and Revisions. Each Revision has a page_id referencing the Page, a page relationship to the referenced page; each Page has a all_revisions relationship to all its revisions. So far so common. But I want to implement different epochs for the pages: If a page was deleted and is recreated, the new revisions have a new epoch. To help find the correct revisions, each page has a current_epoch field. Now I want to provide a revisions relation on the page that only contains its revisions, but only those where the epochs match. This is what I've tried: revisions = relationship('Revision', primaryjoin = and_( 'Page.id == Revision.page_id', 'Page.current_epoch == Revision.epoch', ), foreign_keys=['Page.id', 'Page.current_epoch'] ) Full code (you may run that as it is) However this always raises ArgumentError: Could not determine relationship direction for primaryjoin condition ...`, I've tried all I had come to mind, it didn't work. What am I doing wrong? Is this a bad approach for doing this, how could it be done other than with a relationship?

  • Java map with values limited by key's type parameter

    - by Ashley Mercer
    Is there a way in Java to have a map where the type parameter of a value is tied to the type parameter of a key? What I want to write is something like the following: public class Foo { // This declaration won't compile - what should it be? private static Map<Class<T>, T> defaultValues; // These two methods are just fine public static <T> void setDefaultValue(Class<T> clazz, T value) { defaultValues.put(clazz, value); } public static <T> T getDefaultValue(Class<T> clazz) { return defaultValues.get(clazz); } } That is, I can store any default value against a Class object, provided the value's type matches that of the Class object. I don't see why this shouldn't be allowed since I can ensure when setting/getting values that the types are correct. EDIT: Thanks to cletus for his answer. I don't actually need the type parameters on the map itself since I can ensure consistency in the methods which get/set values, even if it means using some slightly ugly casts.

  • Drawing bezier curve with limited subdivisions in OpenGL

    - by xEnOn
    Is it possible to tell OpenGL to draw a 4 degree (5 control points) bezier curve with 10 subdivisions? I was trying with this: point ctrlpts[] = {..., ..., ..., ...}; glMap1f(GL_MAP1_VERTEX_3, 0, 1, 3, 5, ctrlpts); glBegin(GL_LINE_STRIP); for (i = 0; i <= 30; i++) glEvalCoord1f((GLfloat) i/30.0); glEnd(); But this just draws the curve nicely. I am thinking that I want the algorithm inside the bezier curve to draw only until 10 subdivisions and then stop. The line should look a little facet.

  • MapReduce results seem limited to 100?

    - by user1813867
    I'm playing around with Map Reduce in MongoDB and python and I've run into a strange limitation. I'm just trying to count the number of "book" records. It works when there are less than 100 records but when it goes over 100 records the count resets for some reason. Here is my MR code and some sample outputs: var M = function () { book = this.book; emit(book, {count : 1}); } var R = function (key, values) { var sum = 0; values.forEach(function(x) { sum += 1; }); var result = { count : sum }; return result; } MR output when record count is 99: {u'_id': u'superiors', u'value': {u'count': 99}} MR output when record count is 101: {u'_id': u'superiors', u'value': {u'count': 2.0}} Any ideas?

  • Trial vs free with limited functionality

    - by Morten K
    Hi everyone, Not a programming question as such, but a bit more business oriented question about software product development. We have just released a small app, and is offering a free, fully functional trial which lasts for 15 days. I have the gut feeling however, that to reach any kind of penetration on the web, we'd need to offer a version which is free forever, but then has a few limitations in terms of functionality (still quite usable, but not full-throttle). For example, the Roboform browser plugin is somewhat similar in purpose to ours. Not functionality wise, but it's basically a little util that saves time and removes some repetitive-action pain. They offer a free version with limitations and then a pro version for around 30 USD. Roboform has gotten very much attention over the years, and I can't help to think that this is because they have a product which is obviously good, but also free, thus adoption becomes much higher than if they had only offered a 15 day trial. I am wondering if any of you have experience in a similar scenario? Or any thoughts on the two models? Again, I know it's not directly programming related, but it's still a question I feel best answered by a community of developers.

  • Trying to run multiple HTTP requests in parallel, but being limited by Windows (registry)

    - by Nailuj
    I'm developing an application (winforms C# .NET 4.0) where I access a lookup functionality from a 3rd party through a simple HTTP request. I call an url with a parameter, and in return I get a small string with the result of the lookup. Simple enough. The challenge is however, that I have to do lots of these lookups (a couple of thousands), and I would like to limit the time needed. Therefore I would like to run requests in parallel (say 10-20). I use a ThreadPool to do this, and the short version of my code looks like this: public void startAsyncLookup(Action<LookupResult> returnLookupResult) { this.returnLookupResult = returnLookupResult; foreach (string number in numbersToLookup) { ThreadPool.QueueUserWorkItem(lookupNumber, number); } } public void lookupNumber(Object threadContext) { string numberToLookup = (string)threadContext; string url = @"http://some.url.com/?number=" + numberToLookup; WebClient webClient = new WebClient(); Stream responseData = webClient.OpenRead(url); LookupResult lookupResult = parseLookupResult(responseData); returnLookupResult(lookupResult); } I fill up numbersToLookup (a List<String>) from another place, call startAsyncLookup and provide it with a call-back function returnLookupResult to return each result. This works, but I found that I'm not getting the throughput I want. Initially I thought it might be the 3rd party having a poor system on their end, but I excluded this by trying to run the same code from two different machines at the same time. Each of the two took as long as one did alone, so I could rule out that one. A colleague then tipped me that this might be a limitation in Windows. I googled a bit, and found amongst others this post saying that by default Windows limits the number of simultaneous request to the same web server to 4 for HTTP 1.0 and to 2 for HTTP 1.1 (for HTTP 1.1 this is actually according to the specification (RFC2068)). The same post referred to above also provided a way to increase these limits. By adding two registry values to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings] (MaxConnectionsPerServer and MaxConnectionsPer1_0Server), I could control this myself. So, I tried this (sat both to 20), restarted my computer, and tried to run my program again. Sadly though, it didn't seem to help any. I also kept an eye on the Resource Monitor (see screen shot) while running my batch lookup, and I noticed that my application (the one with the title blacked out) still only was using two TCP connections. So, the question is, why isn't this working? Is the post I linked to using the wrong registry values? Is this perhaps not possible to "hack" in Windows any longer (I'm on Windows 7)? Any ideas would be highly appreciated :) And just in case anyone should wonder, I have also tried with different settings for MaxThreads on ThreadPool (everyting from 10 to 100), and this didn't seem to affect my throughput at all, so the problem shouldn't be there either.

  • iTune redeem codes: limited to a single version?

    - by Big Papoo
    Hi, I'm wondering if V1.0 generated redeem codes will be usable on a V1.1 version of my app? BTW, I know redeem codes are valid only 4 weeks and I also know that apps downloaded with a redeem code can be upgraded for free as with paid ones. My concern here is just: do unused redeem codes become invalid when a new version of my app will be available on the store? Apple's doc is not clear about this point. Did someone experience this yet ? Thx. --GQ.

  • Database design efficiency with 1 to many relationships limited 1 to 3

    - by Joe
    This is in mysql, but its a database design issue. If you have a one to many relationship, like a bank customer to bank-accounts, typically you would have the table that records the bank-account information have a foreign key that keeps track of the relationship between account and customer. Now this follows the 3rd normal form thing and is a widely accepted way of doing it. Now lets say that you are going to limit a user to only having 3 accounts. The current database implementation will support this and nothing would need to change. But another way to do this would have 3 coloms in the account table that have the id of the 3 respective accounts in them. By the way this violates 1st normal form of db design. The question is what would be the advantage and disadvantages of having the user account relationship recored in this way over the traditional?

  • ListItemCollection is limited to 127 items?

    - by HeavyWave
    I am trying to add a lot of item to ListItemCollection in the ListControl, but once the Count reaches 127 I can't add any more items. It doesn't throw any exceptions, just doesn't add the items. I have changed Capacity to 256, but it still won't add more than 127 items. Is there a hard-coded limit?

  • Limited recursion in C?

    - by function
    I ran this program and it output ... 65088 65089 65090 and then it stopped. Windows 7 said a.exe stopped working. Here is the code: #include <stdio.h> void go(void); main() { go(); } void go(void) { static int i = 0; printf("%d\n", i++); go(); } I think this program should keep on printing numbers indefinitely due to recursion, but it stops at 65090! The C code is compiled with gcc. Any ideas?

  • Introducing a new Umbraco datatype for Multi-lingual websites.

    - by Vizioz Limited
    Over the last 6 months we have been building various multi-lingual sites for different clients and for some of the clients they have 1 to 1 relationships between some or all of their pages.Within Umbraco, you can copy a page ( or whole tree of pages ) and keep a relationship between each of the pages and their new copy, this allows content editors to subscribe to change notifications that Umbraco can create if one of the linked pages is changed.Unfortunately one thing that is missing in Umbraco is any way to see which pages are related to each other and to have a quick and easy way to jump between the related pages.We created a datatype that solves these problems and thought we would release it as an open source project ( which we are still maintaining )Currently you can:1) See current relationships2) Add relationships3) Limit the number of relationships that can be added ( by the data type )4) See the Country flag ( assuming a culture has been set on each of your top level site nodes for each country site )5) Link between the documents6) Change or delete the linksAn example where multiple languages are allowed:An example where only 2 languages exist (1 relationship):You can download the datatype from the Umbraco project page:Vizioz Relationships for UmbracoPlease do let us know what you think :)
