    <p>I have got this Runtime Error when running this code:</p> <pre><code>void AlienShipManager::Update(float timeDelta, BulletManager* bulletManager, ParticleManager* particleManager, GameStringSystem* stringBatch) { unsigned int i = 0; while (i &lt; m_alienShipList.size()) { AlienResult result = m_alienShipList[i].Update(timeDelta, bulletManager); switch (result) { case AlienResult::Dead: break; default: break; } ++i } } </code></pre> <p>in line</p> <pre><code>AlienResult result = m_alienShipList[i].Update(timeDelta, bulletManager); </code></pre> <p>There is how I add AlienShip to vector class:</p> <pre><code>m_alienShipList.push_back(AlienShip(position, speed, m_screeSize, m_alienShipTexture)); </code></pre> <p>error also appers if I chance that to:</p> <pre><code>AlienShip* newAlien = new AlienShip(position, speed, m_screeSize, m_alienShipTexture); m_alienShipList.push_back(*newAlien); delete newAlien; </code></pre> <p>but does not appear if I change that to:</p> <pre><code>AlienShip* newAlien = new AlienShip(position, speed, m_screeSize, m_alienShipTexture); m_alienShipList.push_back(*newAlien); </code></pre> <p>which hence lead to huge memory leaks.</p> <p>This is how looks my AlienShip class:</p> <pre><code>#pragma once #include "Body.h" #include "BulletManager.h" #include "ParticleManager.h" enum AliensShipState { flying, dying, dead, escaped }; enum AlienResult { No, Hit, Dying, Dead, Escaped }; class AlienShip : public Body { public: AlienShip(void); AlienShip(float2&amp; position, float2&amp; speed, float2* screenSize, ID3D11Texture2D* alienTexture); ~AlienShip(void); AlienResult Update(float timeDelta, BulletManager* bulletManager); void Draw(BasicSprites::SpriteBatch^ spriteBatch); protected: float m_baseY; AliensShipState m_state; float2* m_screenSize; }; </code></pre> <p>AlienShip class is inherited from Body class, which has Sprite class inside it, which has another vector inside it. But since Sprite class is working perfectly elsewhere, I don't think it is source of error.</p> <p>I wonder why this happens, because I can't find the relationship between deleting temporary object and corrupting vector iterator, If it corrupted at all.</p> <p>Also program compiles and runs in Release, but with some data corruption. </p> <p>I am using Visual Studio 2012 Beta for Windows 8.</p> <p>Please write if you need more source code. Unfortunately it is very hard to post all code, as this is complex program.</p>

    1. COThe code you posted is certainly not the original. There is a `;` missing and it shouldn't compile. It seems you are not understanding some fundamental `C++` concepts, like memory management and value-semantics. Also, this looks like C++-cli.

    3. COThe symptoms suggest that "the rule of three" is violated somewhere within `AlienShip` class, but it is not obvious from the code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
