我寫一個MDI的application
其中有mainForm,childForm以及analysis
mainForm中
//.cpp
void __fastcall TForm1::ToolButton11Click(TObject *Sender)
{
bool i=isImage();
if(i){
if((TimageForm *)ActiveMDIChild )
{
imageForm=(TimageForm *)ActiveMDIChild;
imageForm->ToothAnal();
}
}
}

childForm中
//.cpp
#include "ToothAnalysis.h"
ToothAnalysis *TA;
void TimageForm::ToothAnal()
{
int x,y;
float tempx,tempy;
x=ScrollBox1->HorzScrollBar->Position;
y=ScrollBox1->VertScrollBar->Position;
unsigned int featurePositionX[5];
unsigned int featurePositionY[5];
for(int i=0;i<5;i ){
tempTImage = (TImage *)(FindComponent(toothFeatureName[i]));
featurePositionX[i]=tempTImage->Left x;
featurePositionY[i]=tempTImage->Top y;
}
TA->LoadData(featurePositionX,featurePositionY,scale);
}

ToothAnalysis中
//.cpp
void ToothAnalysis::LoadData(unsigned int dataX[],unsigned int dataY[],float loadScale)
{
scale=loadScale;
}

compiler可以過 但執行會出現 EAcessViolation with message........錯誤訊息
請問該如何作才對

應該是 FormStyle 的設定問題。
試著把

1: mainFrom 的 FormStyle 設定為 MDIForm
2: 其它 Form 的 FormStyle 設字為 MDIChild 看看
