我現在使用BCB然後加上SPCOMM元件抓取RS232的資料
但是再接收數次後 就會跳出附檔的訊息
請問各位 這個有可能是什麼情況

附加檔案：4d39485d8ab55_未命名.JPG

指標指向錯誤的記憶體位置。一般是…
1/ 沒有配置記憶體就使用，即沒有new…
2/ 被指向的地方已被釋放，但你還是去存取
總之，應該不會是spcomm的問題，而是你自己的實作部份，關於指標、初始化，配置等有問題。

她顯示 是在ch = fgetc(setting);
這行會停住
當我傳送了十次左右的DATA就會跳出剛剛的訊息
是我這邊寫錯了嗎?
麻煩您幫我看一下 謝謝
[code cpp]
void __fastcall TForm1::CheckBox5Click(TObject *Sender)
{
if(CheckBox5->Checked == true && Edit_ID->Text.Length() == 10)
{
int i;
char ch,countx;
sprintf(filename, "measure_data\\%s_measure.txt", Edit_ID->Text);
FILE *setting = fopen(filename,"r");
i = 0;
countx = 0;
String ss = "" ;
ch = 0;
float aa[100][1];
do{
ch = fgetc(setting);
if(ch == ',' || ch == '_' || ch == '/' || ch == 0x0D || ch == '\n')
i ;
switch(i)
{
case 6:
if(ch != ',')
{
ss = ch;
// weight
}
break;
case 7:
if(ch == ',')
{
/* Weight */
aa[countx][0]=StrToFloat(ss);//AnsiString(ss);
if(CheckBox5->Checked == true)
Series10->AddY(aa[countx][0]);
countx ;
ss = "";
}
break;
default:
break;
}
if(i == 14)
i = 0;
}while(ch != EOF);
}
else
Series10->Clear();
}[/code]

編輯記錄

大致粗略看一下，建議先調整如下:

StrToFloat 改成 StrToFloatDef(ss,0)

ss = ch; 改成 ss = AnsiString(ch) --> 很重要，不要以為這樣寫很癈物，因為可能會有意想不到的情形…說來話太長，照做就是。

float aa[100][1]; 改成; float aa[100][1] = {0};

StrToFloatDef(ss,0) 前面 請加入 if (countx > 100) ShowMessage("Out of boundary") // 查看是否有出界的情形。

   謝謝您的指導~前面的已經沒有再跳出錯誤
可是他現在出現一樣的訊息 只是改出現在下面紅色那行
我真的找不太到問題耶@@


FILE *output; // 用來指向一個輸出的位置
sprintf(filename, "patient_data\\%s_patient.txt", Edit_ID->Text);
output=fopen(filename,"w"); // 第1個參數是檔名, 第2個參數是開啟檔案的模式, w代write, t代text
fprintf( output, "%s,%s\n",Edit_name->Text,Edit_patient->Text );
while(0 == fclose(output));
sprintf(filename, "measure_data\\%s_measure.txt", Edit_ID->Text);
output=fopen(filename,"a"); // 第1個參數是檔名, 第2個參數是開啟檔案的模式, w代write, t代text
fprintf( output, "%s_%s\n",Label_date->Caption,buf);
while(0 == fclose(output));

sprintf(filename, "patient_data\\%s_patient.txt", .c_str() );


注意 sprintf 與fprintf 中的 s% 是要你輸入 char＊ 而非 AnsiString，所以都要轉一下。

這次又停在
fprintf( output, "%s_%s\n",Label_date->Caption,buf);
加上
Label_date->Caption.c_str()

也是一樣會停在這邊
麻煩幫我看一下了 謝謝



[code cpp]
sprintf(filename, "measure_data\\%s_measure.txt", Edit_ID->Text.c_str());
output=fopen(filename,"at"); // 第1個參數是檔名, 第2個參數是開啟檔案的模式, w代write, t代text
fprintf( output, "%s_%s\n",Label_date->Caption,buf);
while(0 == fclose(output));
[/code]

1/ 一定要Label_date->Caption.c_str()
2/ 關鍵點 你的 buf 是什麼型別? 沒看到宣告
