  • Get Confirm value in vb.net

    - by user1805641
    I have a hidden asp Button in a Repeater. In the VB.NET code behind I use the Rerpeater_ItemCommand to get the click event within the Repeater. There's a check if user is already recording a project. If yes and he wants to start a new one, a confirm box should appear asking "Are you sure?" How can I access the click value from confirm? <asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand"> <ItemTemplate> <div class="tile user_view user_<%# Eval("employeeName") %>"> <div class="tilesheight"></div> <div class="element"> <asp:Button ID="Button1" CssClass="hiddenbutton" runat="server" /> Index: <asp:Label ID="Label1" runat="server" Text='<%# Eval("index") %>' /><br /> <hr class="hr" /> customer: <asp:Label ID="CustomerLabel" runat="server" Text='<%# Eval("customer") %>' /><br /> <hr class ="hr" /> order: <asp:Label ID="OrderNoLabel" runat="server" Text='<%# Eval("orderNo") %>' /><br /> <asp:Label ID="DescriptionLabel" runat="server" Text='<%# Eval("description") %>' /><br /> <hr class="hr" /> </div> </div> </ItemTemplate> </asp:Repeater> code behind: If empRecs.Contains(projects.Item(index.Text).employeeID) Then 'Catch index of recording order i = empRecs.IndexOf(projects.Item(index.Text).employeeID) Page.ClientScript.RegisterStartupScript(Me.GetType, "confirm", "confirm('Order " & empRecs(i + 2) & " already recording. Would you like to start a new one?')",True) 'If users clicks ok insertData() End If Other solutions are using the Click Event and a hidden field. But the problem is, I don't want the confirmbox to appear every time the button is clicked. Only when empRecs conatins an employee. Thanks for helping

  • NSFetchedResultsChangeUpdate crashes when called on a searched tableview

    - by Zachary Fisher
    So I nearly have this thing figured out, but I am stumbling over the NSFetchedResultsChangeUpdate when I update my managedObjectContext from a detail view that was entered after searching the table. I have a tableview generated from a core data set. I can enter a detail view from this table and make changes without any issue. I can also search the table and make changes MOST of the time without any issues. However, on certain objects, I get an "Exception was caught during Core Data change processing". I tracked this down to the NSFetchedResultsChangeUpdate. I'm using the following code: case NSFetchedResultsChangeUpdate: if (searchTermForSegue) { NSLog(@"index info:%@.....",theIndexPath); NSLog(@"crashing at the next line"); [self fetchedResultsController:self.searchFetchedResultsController configureCell:[tableView cellForRowAtIndexPath:theIndexPath] atIndexPath:theIndexPath]; break; } else { [self fetchedResultsController:controller configureCell:[tableView cellForRowAtIndexPath:theIndexPath] atIndexPath:theIndexPath]; } break; When the table is not being searched, it runs the else method and that works 100% of the time. When the table is being searched, it runs the if (searchTermForSegue) and that works most of the time, but not always. I logged theIndexPath and discovered the following: When it works, theIndexPath is correctly reporting the objects indexPat, when it fails, the wrong theIndexPath has been called. For example, if I do a search that narrows the tableView to 3 sections, 2 items in first, 1 in second, 1 in third, I get the following nslog: On first object: index info:<NSIndexPath 0xb0634d0> 2 indexes [0, 0]..... on second object: index info:<NSIndexPath 0xb063e70> 2 indexes [0, 1]..... on third object: index info:<NSIndexPath 0xb042880> 2 indexes [1, 0]..... but on the last object: index info:<NSIndexPath 0x9665790> 2 indexes [2, 17]..... it should be calling [2, 0] Note that I am simply updating these objects, not deleting them or adding new ones. Any thoughts would be appreciated!

  • SQL Server 2008 - Query takes forever to finish even though work is actually done

    - by Brian
    Running the following simple query in SSMS: UPDATE tblEntityAddress SET strPostCode= REPLACE(strPostCode,' ','') The update to the data (at least in memory) is complete in under a minute. I verified this by performing another query with transaction isolation level read uncommitted. The update query, however, continues to run for another 30 minutes. What is the issue here? Is this caused by a delay to write to disk? TIA

  • Simplifying const Overloading?

    - by templatetypedef
    Hello all- I've been teaching a C++ programming class for many years now and one of the trickiest things to explain to students is const overloading. I commonly use the example of a vector-like class and its operator[] function: template <typename T> class Vector { public: T& operator[] (size_t index); const T& operator[] (size_t index) const; }; I have little to no trouble explaining why it is that two versions of the operator[] function are needed, but in trying to explain how to unify the two implementations together I often find myself wasting a lot of time with language arcana. The problem is that the only good, reliable way that I know how to implement one of these functions in terms of the other is with the const_cast/static_cast trick: template <typename T> const T& Vector<T>::operator[] (size_t index) const { /* ... your implementation here ... */ } template <typename T> T& Vector<T>::operator[] (size_t index) { return const_cast<T&>(static_cast<const Vector&>(*this)[index]); } The problem with this setup is that it's extremely tricky to explain and not at all intuitively obvious. When you explain it as "cast to const, then call the const version, then strip off constness" it's a little easier to understand, but the actual syntax is frightening,. Explaining what const_cast is, why it's appropriate here, and why it's almost universally inappropriate elsewhere usually takes me five to ten minutes of lecture time, and making sense of this whole expression often requires more effort than the difference between const T* and T* const. I feel that students need to know about const-overloading and how to do it without needlessly duplicating the code in the two functions, but this trick seems a bit excessive in an introductory C++ programming course. My question is this - is there a simpler way to implement const-overloaded functions in terms of one another? Or is there a simpler way of explaining this existing trick to students? Thanks so much!

  • How to face observable object containing an observable field

    - by iseek
    Hello, I need a hint concerning MVC and Observer-Pattern. For example a model contains the classes "Address" and "Person". The Address class contains the fields street:String, zipcode:String, location:String. Whereas the Person class contains the fields name:String, firstName:String, address:Address. My approach so far looks something like this: Both, Address and Person are observable. If one of their setters is being called, I validate whether the current value and new value differ. Only in this case an update event is fired. The event contains the source, the name of the changed field, the old and the new value. The class for the view contains text fields to display and edit the information of a person: name, firstname, street, zipcode, location. It knows the Person model and is an subscribed observer for the person. So it gets the update events from the person object. My questions concerns the address field from type Address in the person class, since an address is observable on its own. If the view gets an update event from person when a new address has been set, I can update all of the address related fields in the view. But what if a field of the address changes? Should the view also register for update events from the address? Any hints about common design approaches would be appreciated. Greetings.

  • Python: Time a code segment for testing performance (with timeit)

    - by Mestika
    Hi, I've a python script which works just as it should but I need to write the time for the execution. I've gooled that I should use timeit but I can't seem to get it to work. My Python script looks like this: import sys import getopt import timeit import random import os import re import ibm_db import time from string import maketrans myfile = open("results_update.txt", "a") for r in range(100): rannumber = random.randint(0, 100) update = "update TABLE set val = %i where MyCount >= '2010' and MyCount < '2012' and number = '250'" % rannumber #print rannumber conn = ibm_db.pconnect("dsn=myDB","usrname","secretPWD") for r in range(5): print "Run %s\n" % r ibm_db.execute(query_stmt) query_stmt = ibm_db.prepare(conn, update) myfile.close() ibm_db.close(conn) What I need it the time it takes the execution of the query and written to the file "results_update.txt". The purpose is to test an update statement for my database with different indexes and tuning mechanisms. Sincerely Mestika

  • Can I store and join based on external attributes in Lucene/Solr

    - by Kibbee
    Is there a way to store information about documents that are stored in Lucene such that I don't have to update the entire document to update certain attributes about the documents? For instance, let's say I had a bunch of documents, and that I wanted to update a permissions list of who was allowed to see the documents on a daily, or more frequent, basis. Would it be possible to update all the permissions each day, without updating all the documents. I could do it by keeping a exactly which permissions were added and removed, but I would rather just be able to take the end list of permissions, and use that, rather than have to keep track of all the permission changes and post those entire documents to Lucene.

  • mysql circular dependency in foreign key constraints

    - by Flavius
    Given the schema: What I need is having every user_identities.belongs_to reference an users.id. At the same time, every users has a primary_identity as shown in the picture. However when I try to add this reference with ON DELETE NO ACTION ON UPDATE NO ACTION, MySQL says #1452 - Cannot add or update a child row: a foreign key constraint fails (yap.#sql-a3b_1bf, CONSTRAINT #sql-a3b_1bf_ibfk_1 FOREIGN KEY (belongs_to) REFERENCES users (id) ON DELETE NO ACTION ON UPDATE NO ACTION) I suspect this is due to the circular dependency, but how could I solve it (and maintain referential integrity)?

  • What is wrong with my @synchronized block?

    - by hyn
    I have 2 threads in my application, a game update thread and render/IO/main thread. My update thread updates the game state, and the render thread renders the scene based on the updated values of the game state models and a few other variables stored inside an object (gameEngine). The render thread gets executed while the game thread is still updating, which is a problem, so it appeared to me the solution is to use @synchronized like this: @synchronized(gameEngine) { [gameEngine update]; nextUpdate = now + GAME_UPDATE_INTERVAL; gameEngine.lastGameUpdateInterval = now - lastUpdate; gameEngine.lastGameUpdateTime = now; lastUpdate = now; } But the render thread still accesses the gameEngine object between -update and the last 3 lines of the block. Why is this?

  • Stored procedure and trigger

    - by noober
    Hello all, I had a task -- to create update trigger, that works on real table data change (not just update with the same values). For that purpose I had created copy table then began to compare updated rows with the old copied ones. When trigger completes, it's neccessary to actualize the copy: UPDATE CopyTable SET id = s.id, -- many, many fields FROM MainTable s WHERE s.id IN (SELECT [id] FROM INSERTED) AND CopyTable.id = s.id; I don't like to have this ugly code in trigger anymore, so I has extracted it to a stored procedure: CREATE PROCEDURE UpdateCopy AS BEGIN UPDATE CopyTable SET id = s.id, -- many, many fields FROM MainTable s WHERE s.id IN (SELECT [id] FROM INSERTED) AND CopyTable.id = s.id; END The result is -- Invalid object name 'INSERTED'. How can I workaround this? Regards,

  • Updating Pointer using signals and slots

    - by Umesha MS
    Hi, I am very new to the QT; please help me to solve the problem. I am using thread to perform intensive operation in back ground. Meanwhile I want to update the UI, so I am using SIGNALS and SLOTS. To update UI I emit a signal and update UI. Let us consider bellow sample code, struct sample { QString name; QString address; }; void Update(sample *); void sampleFunction() { sample a; a.name = "Sachin Tendulkar"; a.address = "India" emit Update(&a); } In the above code we are creating a local object and passing the address of local object. In the QT document, it says that when we emit a signal it will be placed in the queue and late it will be delivered to the windows. Since my object is in local scope it will be delete once it goes out of the scope. Please tell me a way to send a pointer in a signal.

  • Make sure base method gets called in C#

    - by Fnatte
    Can I somehow force a derived class to always call the overridden methods base? public class BaseClass { public virtual void Update() { if(condition) { throw new Exception("..."); // Prevent derived method to be called } } } And then in a derived class : public override void Update() { base.Update(); // Forced call // Do any work } I've searched and found a suggestion to use a non-virtual Update() but also a protected virtual UpdateEx(). It just doesn't feel very neat, isn't there any better way? I hope you get the question and I am sorry for any bad English.

  • git submodule pull and commit automatically on webserver

    - by Lukas Oppermann
    I have the following setup, I am working on a project project with the submodule submodule. Whenever I push changes to github it sends a post request to update.php on the server. This php file executes a git command. Without submodules I can just do a git pull and everything is fine but with submodules it is much more difficult. I have this at the moment, but it does not do what I want. I should git pull the repo and update and pull the latest version of each submodule. <?php echo `git submodule foreach 'git checkout master; git pull; git submodule update --init --recursive; git commit -m "updating"' && git pull && git submodule foreach 'git add -A .' && git commit -m "updating to latest version including submodules" 2>&1s`; EDIT// Okay, I got it half way done. <?php echo `git submodule foreach 'git checkout master; git pull; git submodule update --init --recursive; git commit -am "updating"; echo "updated"' && git pull && git commit -am "updating to latest version including submodules" && echo 'updated'`; The echo prevents the script to stop because of non-zero returned. It works 100% fine when I run it from the console using php update.php. When github initialized the file, or I run it from the browser it still does not work. Any ideas?

  • SVN - How to export changed files in dependency project when create updates?

    - by Relax
    I have a project with it depends on another project Core, i use svn:external to maintain the dependency. when i go to create an update of my project, i export those changed files of two tags of my project, but the changed files in Core won't be exported. For example, my project 2.0 depends on Core 1.0, where 3.0 depends on Core 2.0, then i create an update, changed files of my project 3.0 will all be exported, but none of those in Core 2.0 This can be done thru a two-steps process, first export changed files of the project 3.0, then the Core 2.0, it is ok if i can remember it everytime when i create an update, but in case i forget someday, the broken update will most probably cause a crash. I wonder, is there a way to cover this situation in TortoiseSVN, will let me do it in one operation? I use TortoiseSVN + VisualSVN

I want to update my page when update or new request to save data is sent but if i update this function(edit-in-place) it will add second set of buttons, third, fourth and so on. How could i tell it that it would update just on that returned data, but not all elements? I have an idea it has to do something with each function of jquerys, but I'm not sure as I'm quite new to jquery. Thanks for any help!

  • How do I access the enumerated item with an indexer and assign array string to it for display?

    - by g00p3k
    EDITED: Updated 3/23/09. See rest of post at bottom. I'm still having trouble with the indexer. Anymore help or examples would really help me out. Write a class, MyCourses, that contains an enumeration of all the courses that you are currently taking. This enum should be nested inside of your class MyCourses. Your class should also have an array field that provides a short description (as a String) of each of your courses. Write an indexer that takes one of your enumerated courses as an index and returns the String description of the course. Write a class MyFriends that contains an indexer that provides access to the names of your friends. namespace IT274_Unit4Project { public class MyCourses { // enumeration that contains an enumeration of all the courses that // student is currently enrolled in public enum CourseName {IT274= 0,CS210 = 1} // array field that provides short description for each of classes, // returns string description of the course private String[] courseDescription = {"Intermediate C#: Teaches intermediate elements of C# programming and software design", "Career Development Strategies: Teaches principles for career progression, resume preparation, and overall self anaylsis"}; // indexer that takes one of the enumerated courses as an index // and returns the String description of the course public String this[CourseName index] { get { if (index == 1) return courseDescription[0]; else return courseDescription[1]; } set { if (index == 1) courseDescription[0] = value; else courseDescription[1] = value; } } } }//end public class MyCourses I'm working on this homework project and having trouble understanding the text explaining how to correctly take the accessed value of the enumeration and then apply the string array value to it. Can you please help me understand this? The text we are using is very difficult and poorly written for a beginner to understand, so I'm kind of on my own here. I've got the first parts written, but need some help on the accessing of the enumeration value and assigning, i think i'm close, but don't understand how to properly get and set the values on this. Please do not provide me with direct code answers, unless a MSDN style explanation that is generalized and not specific to my project. ie: public class MyClass { string field1; string field2; //properties public string Value1 get etc... Thanks!

  • Load Empty Database table

    - by john White
    I am using SQLexpress and VS2008. I have a DB with a table named "A", which has an IdentitySpecification column named ID. The ID is auto-incremented. Even if the row is deleted, the ID still increases. After several data manipulation, the current ID has reached 15, for example. When I run the application if there's at least 1 row: if I add a new row, the new ID is 16. Everything is fine. If the table is empty (no row): if I add a new row, the new ID is 0, which is an error (I think). And further data manipulation (eg. delete or update) will result in an unhandled exception. Has anyone encountered this? PS. In my table definition, the ID has been selected as follow: Identity Increment = 1; Identity Seed =1; The DB load code is: dataSet = gcnew DataSet(); dataAdapter->Fill(dataSet,"A"); dataTable=dataSet->Tables["A"]; dbConnection->Open(); The Update button method dataAdapter->Update(dataSet,"tblInFlow"); dataSet->AcceptChanges(); dataTable=dataSet->Tables["tblInFlow"]; dataGrid->DataSource=dataTable; If I press Update: if there's at least a row: the datagrid view updates and shows the table correctly. if there's nothing in the table (no data row), the Add method will add a new row, but from ID 0. If I close the program and restart it again: the ID would be 16, which is correct. This is the add method row=dataTable->NewRow(); row["column1"]="something"; dataTable->Rows->Add(row); dataAdapter->Update(dataSet,"A"); dataSet->AcceptChanges(); dataTable=dataSet->Tables["A"];
